Software Development: Outsourcing vs Outstaffing Difference

In this article we’ve covered in house development vs outstaffing discussion, so now you should have an idea of how you can use a remote provider to your benefit. Choosing the right outsourcing partner for your project is 60% of success. Because outsourcing your project means remote work, you need to make sure your partners are reliable, professional, and honest. A good practice is to make a list of all outsourcing companies that specialize in developing the software you need. You can shortlist vendors by searching for them in Google, asking your business partners for recommendations, or researching the listings of software developers such as Clutch.

The extension was developed by Chris Pederick, who has also authored the User Agent Switcher extension. Since the employee does not work for you, you do not need to form his personal file, make out various certificates, sick leave, take it into account when submitting statistical reports and so on. In this way, the workload of the HR Department is considerably reduced . Skilled in professional and accurate optimization of database queries.

The client had enough time to concentrate on the company’s growth and had an opportunity to cooperate with the top engineers. Development and SEO optimisation of websites, content preparation.

The main difference between outsourcing and outstaffing in software development lies in the management, control, and responsibility peculiarities. In outsourcing, the hired tech team is the only team that’s involved in the development process from A to Z and is responsible for the resources, management, and end result. A dedicated offshore team consists of two or more high-quality developers involved in the development of a particular part of the project.

No Actual Communication is Required

Different management practices can bring copious problems to the table. Still, it feels like this problem can be easily avoided by a fruitful discussion you can have with your vendor at the very beginning of cooperation. We’ve picked a .NET developer and some time later the team grew up to 10 persons hired by us, including a team leader, a project manager, and a system administrator. We’ve completely taken up the burdens of documents management, hiring & recruitment processes, and office management of the client’s shoulders.

Service quality and experience

This type of employment is special because a company outstaffs a certain part of its legally registered employees to fulfill their duties and execute the tasks set by the customer company. Probably the most popular hiring model among big companies is outsourcing. In a nutshell, the company still gives a task to a third-party member, but they work with the project for a longer period of time.

This is the key to avoiding important miscommunications. At ProCoders, all of our developers are language tested as we do not hire anyone who does not speak English. If a specialist is technically very good, but their English level is not high enough, how to hire a net developer we hire them, but before putting him on a project, we provide them with English language courses. However, if you are considering outsourcing, you’ll need to ask yourself different questions. Do you have the extra budget outsourcing will require?

Advantages and Disadvantages of Outsourcing

Miscommunication is easy if the way companies work is too different. Providing strategic guidance with regards to technology, infrastructures and enabling major business processes changes through enhancements to IT. The individuals are capable of definition of principles, ROI , services, standards, guidelines and solutions for an IT-Platform or portfolio. Look for providers that focus on both a vertical and a software language.

4 6. In-depth Look: Tuckmans Model Five Stages of Team Development Strategic Project Management: Theory and Practice for Human Resource Professionals

Team members may take on different tasks to support each other as they work toward common goals. As a team leader, it is essential to remember that overlap between the second and third stages might occur. Your team can hunch back to the previous stage or while handling the challenging aspects of the project.

Members may disagree on team goals, and subgroups and cliques may form around strong personalities or areas of agreement. To get through this stage, members must work to overcome obstacles, to accept individual differences, and to work through conflicting ideas on team tasks and goals. While these four stages—forming, storming, norming, and performing—are distinct and generally sequential, they often blend into one another and even overlap. For example, if a new member joins the team there may be a second brief period of formation while that person is integrated. A team may also need to return to an earlier stage if its performance declines.

The Most Effective Ways to Motivate Employees and Increase Productivity

Workgroups become a cohesive team when they learn to appreciate differences. These items are used to deliver advertising that is more relevant to you and your interests. They may also be used to limit the number of times you see an advertisement and measure the effectiveness of advertising campaigns.

team development process

For this reason, team leaders should be at hand to help members return to the norming stage. Team members may feel a variety of concerns about the team’s impending dissolution. They may be feeling some anxiety because of uncertainty about their individual role or future responsibilities. They may feel sadness or a sense of loss about the changes coming to their team relationships. And at the same time, team members may feel a sense of deep satisfaction at the accomplishments of the team.

Team Building Stages: 5 Steps

Provide positive feedback along the way and especially at the end of the project. Implement quick and effective problem-solving strategies with your HR team. Create a space for easy and open communication, such as a chat app. Utilise a white board or post-it notes to make every team member’s ideas seen. Come prepared with relevant and fun questions to get people talking and learning about one another. As we go along, we will explain each of these stages in greater detail.

Team members refocus on established team groundrules and practices and return their focus to the team’s tasks. Having a way to identify and understand causes for changes in the team behaviors can help the team maximize its process and its productivity. The most commonly used framework for a team’s stages of development was developed in the mid-1960s by Bruce W. Tuckman. How did you know what behaviors were acceptable or what level of performance was required?

Assess progress

Remove certain elements of the team’s structure to encourage individuals to take greater responsibility. Establish effective conflict resolution techniques to prevent tension from causing deeper damage. Close to half of executives who responded to a Deloitte survey believe better collaboration will help them increase employee retention. Unfortunately, many organizations don’t reflect that reality, and in the absence of healthy team environments employees tend to work in silos and get things done alone versus collaboratively. When team members change, whether a member leaves or new members join the team, the stages are often repeated.

team development process

Every group of people presents a unique challenge for a leader to tackle. The five stages of team development are designed to help with forming four stages of group development teams and allowing them to thrive at work. Stage two of five is considered the most critical but also the most difficult to go through.

Forming, the first stage of team development:

The ideal is that they will not feel that they are being judged, and will therefore share their opinions and views. The forming stage of team development is the first step in team bonding. In this initial stage, group members gather and learn more about each other.

  • Team members are able to prevent or solve problems in the team’s process or in the team’s progress.
  • As the work load is diminished, individual members may be reassigned to other teams, and the team disbands.
  • The team building process is a step-by-step system for transforming a group of employees into an effective and collaborative unit.
  • Record and store the meeting in Teamwork Projects so that team members can revisit it at any time if they need a reminder of the discussion.
  • For smaller, cross-functional teams, use your main project objective for your team’s mission statement.

At the end of the project, set up an online meeting where team members come together to discuss the entire project, from the successes to the frustrations. Ask them to prepare examples beforehand outlining what worked and what didn’t, and then give each person five minutes to share their thoughts. Document the comments so that it’s easy to see which trends emerge and what changes need to be made going forward. When teams work in the same space, it’s easy to see what everyone’s doing. Designers are talking to product managers to get direction, or product managers meet with analysts to talk about user data and reports.

What are the steps of the team building process?

It’s easier to accomplish tasks at this stage as the members are more involved and they understand the whole process. Team members perform much better when handling collective and individual tasks since they are more optimized at this stage. Everyone is high on the same page and working hard towards the ultimate goal. If you have managed to get your team to this stage, be proud of yourself – as there is only going up.

Top JavaScript Frameworks For Mobile App Development by SPEC INDIA Frontend Weekly

Meteor creates simple, efficient, and scalable mobile applications using the JavaScript framework. It uses a single code base to develop applications for any device. It makes use of an extended and integrated JavaScript stack that helps in offer more with lesser coding involved. Onsen is a simple DOM element that can be used to develop intuitive interfaces for native and hybrid apps. It has three layers- CSS, web and framework bindings- to develop mobile apps.

Flutter code compiles to ARM or Intel machine code as well as JavaScript, for fast performance on any device. When the apps are launched it is cause for celebration, but our support doesn’t end there. Getting accepted on the App Stores, especially by Apple, can be tricky. If you used any of the previously discussed methods you could find yourself struggling to get approval and needing to go back to development for painful rewrites. The partnership starts with a demo call in which we go over your vision for the apps and answer all your questions. After you’ve used Canvas to create the apps we test them thoroughly and take it from there.

Ionic vs Flutter: How to make the right choice

One way to streamline this process and cut down on development time is by using JavaScript. In this post, we’ll explore the benefits of using JavaScript for mobile apps and list mobile development javascript some popular frameworks that you can use. Apache Cordova is one of the most well-liked JavaScript frameworks for mobile development, since it is open-source and adaptable.

IT recruitment agency connecting best tech talents with businesses around the world. These include intricate dynamic interactions and may be developed with frameworks and libraries like Angular, React.js, Polymer.js, and Vue.js. Finally, Cordova’s CLI allows the development of new projects, compiling them on many platforms, and executing them on actual hardware or emulators. By converting templates into code, Angular redefines the current JavaScript virtual machine. Angular apps load more quickly than any other front-end framework used today. There are several frameworks that can be used to create a professional JavaScript app such as PhoneGap, jQuery Mobile, and Ionic.

Sencha Ext JS

You should create an application that requires the capabilities of one of these frameworks. Then, select a framework based on your desired functionality and pay careful attention to your technology stack. Additionally, Meteor’s local storage makes it a popular choice for mobile apps. It removes all the complicated server-side logic for a simple and intuitive user experience. Hence, it’s a preferred option as opposed to the more common cloud integration approach.

NativeScript provides a set of UI components, its router, and UI customization options. EBay was concerned with the dependability of the stack and the effectiveness of handling eBay-specific functions. They switched over to Node.js for their whole user interface stack.

Overview of Cordova APIs

It offers a huge advantage over the regular server-oriented development method. The front-end in JavaScript development employs the locally captured cached data to refresh the app till there is a re-establishment of connectivity. This will aid in local tracking of changes and push them to sever side after the return of connection. It is unique from other apps that depend on constant server connections to carry the key functions. Java Script consists of a UI that loads and functions on a screen without the aid of network connections.

  • After you’ve used Canvas to create the apps we test them thoroughly and take it from there.
  • Over time, your app audience will start to reflect your most loyal and engaged fans.
  • All you need to do is sign up, configure a few settings to customize the apps, then our team takes care of everything else.
  • But specific JavaScript frameworks available today may transform native programs into cross-platform mobile apps utilising a variety of code languages.
  • Enables developers to create highly customized web applications with desired color schemes and various CSS aspects of UI.
  • Microsoft used JavaScript for language support, accessibility, and device-to-device data transfer.
  • It includes native UI components, performance optimizations, and touch-optimized screen layouts.

Chatbots and interactive voice assistants on mobile applications are now more than just a bonus feature thanks to advances in AI. They have developed to the point where they can raise user engagement. Instagram’s mobile app uses JavaScript to run native code on users’ phones dynamically. The native code allows the app to deliver features like video recording, photo filters and geotagging.

The mobile SDK for the Web.

This is a somehwat recent framework developed initially by Facebook. It is a creat option for those seeking to create one app that is adaptable to both Android and iOS devices. It offers great performance, potentially a better one than that provided by some of the other framweorks mentioned here.

In 2022, mobile app development will continue to be a popular pursuit. The range of available mobile devices will allow for more intricate and innovative app designs. The Uber app needs a rapid and scalable technological solution to manage a massive volume of queries. Uber created its native app for iOS and Android, taking advantage of the mobile-optimized environments, user interface and dispatching. Due to the constant influx of requests, the Uber app must contain enormous amounts of data in real-time.

Therefore, anyone with a mere basic understanding of JavaScript can easily leverage VueJs to develop web and mobile apps. JavaScript frameworks are not the end-all of mobile app development technologies. JQuery Mobile’s strengths lie in its fast theme engine and its ability to build hybrid apps with a minimal programming footprint. Apps on jQuery mobile work independently of platforms, ensuring a responsive look on multiple operating systems. Which of the popular Javascript frameworks do you prefer for mobile app development and why?

mobile development javascript

It has held that spot for quite a while, first hitting number one in 2014. Flutter is supported and used by Google, trusted by well-known brands around the world, and maintained by a community of global developers. JavaScript is the computer language used to carry out sophisticated processes on web pages. It includes current scrolling video jukeboxes, recent content changes, animated 2D/3D visuals, interactive maps, etc.

to make your project a reality!

You will need to hire developers (or use your in-house team) to create a hybrid app in Ionic and then prepare your web code with Cordova to fit into it. Apache Cordova is currently one of the most popular frameworks for building Hybrid applications. AI advancements have made chatbots and interactive voice assistants on mobile apps more than an added feature. This is where basic wrapper views should be optimized using other programs and tools such as Canvas. They allow designers to build apps using a working knowledge of app development but without requiring direct coding.

How to Learn Mobile Angular UI

We add native navigation and a native tab menu, native animations, loading indicators and splash screens, and more to create a full, like-native app experience. A better way, which recreates exactly how your JavaScript web app works, along with providing a great mobile user experience, is to use MobiLoud. Unless you built your app in React , your app needs to be rewritten, and recreated, to take advantage of React Native’s cross-platform functions and classes. You’ll need a Cocoa developer to create a webview app in objective-C and configure a few components to make your JavaScript app play nice with it.


As a result, businesses can execute an interactive app that customers love. The combination allows developers to write code once and run it in two languages. While other frameworks need developers to juggle between many programming languages, React Native lets them tap into both at once. One of the old frameworks for hybrid mobile application development, Titanium provides simple and transparent access to most of the native functionalities.

Finally, it is worth mentioning that native mobile applications might be a little bit faster than hybrid applications , because native applications are compiled and native code is optimized. However, applying the common best practices in your hybrid applications can definitely increase your application’s performance to be as close as the native application. In this book, you will learn how to boost the performance of your hybrid mobile application using Apache Cordova and jQuery Mobile. This javascript framework allows building cross-platform mobile apps. React Native apps share 80% of the code for Android and iOS platforms, which means developers are sorted when it comes to logic, APIs, and time for building complex mobile apps. JavaScript frameworks are regarded as the best when it comes to developing and creating efficient mobile apps, especially Android apps.

Javascript can offer the possibility that is not possible with traditional server-side front-end development. We are a team of expert developers, testers and business consultants who strive to deliver nothing but the best. If you have an app idea, we would be happy to take it to the next level and assist you in making it a profitable business. Frameworks are the most popular tool for designing websites because they make coding easier. JavaScript’s frameworks allow programmers to create responsive web applications.

With React Native, one team can maintain multiple platforms and share a common technology—React. Developers always face difficulty to develop apps for all types of mobile devices. This is not an easy job for app engineers as it involves diverse aspects to be covered. But jQuery lets you develop a highly responsive and swift app that will be matching all kinds of devices and even desktop platforms.

Since we’re on the topic of server applications, have you seen Node’s Hello World application? It demonstrates how to build a web server in about 10 lines of code. Of course, you can create much more robust servers using NodeJS or the standard server application framework ExpressJS.

What is a CTO Position? Roles and Responsibilities of a Technical Director

To hire the perfect person, recruiters must fully understand what is a CTO, and what are the roles and responsibilities of this officer. Thus, organizational leaders establish their image of the technological future of the company and identify the objectives for the team. They also establish the sequence in which these objectives should be reached to achieve the desired outcome. It also means that CTOs should keep up with the emerging trends and know the industry inside and out. Cleveroad is a skillful IT outsourcing company headquartered in Estonia, Central Europe. Since 2011, we’ve been assisting startups and organizations of all kinds in acquiring the latest technologies and products.

One of the CTO’s primary responsibilities is finding the best solutions during the development process. Usually, developers ask for help only if they can’t solve the problem themselves. So, the CTO needs to evaluate the problem objectively and find the perfect solution. One of the most challenging aspects of running a startup or a business is finding and hiring qualified tech professionals.

CTOs also work with the engineering and production heads to ensure daily operations are in line with the firm’s goals. Additionally, they also assist in hiring and retention processes, smoothen business operations, introduce innovative ideas, and boost production chief technology officer roles and responsibilities efforts. A great CTO also coordinates among several teams and operations to ensure everyone’s on the same page. You need to handle the technology budget, developer teams and related tasks that means you need to delegate and move away from coding.

These include white papers, government data, original reporting, and interviews with industry experts. We also reference original research from other reputable publishers where appropriate. You can learn more about the standards we follow in producing accurate, unbiased content in oureditorial policy. Many large corporations need both a CTO and CIO, while smaller companies tend to have one or the other.

Professional Services

In order to do this, CTOs need to adopt many different personas within an organization—to the business, you’re the tech guy, and to the technology team, you’re the business guy. This gives the CTO a high level of freedom to operate, but it can also be a lonely place. A report by global cloud services company Access Alto has revealed the four different types of Chief Technology Officer. It pays to understand the difference between the faces and whether your need is of a technical or operational nature.

cto roles and responsibilities

User-centered digitally-powered products are at the heart of most business plans and strategies. And since CTOs act as a bridge between IT and product management, they should supervise the life cycle of a product. Companies also give priority to candidates with ascertained knowledge of customer relations, business management, and marketing. As a result, employment is predicted to increase by 10% between 2019 and 2029. It makes technology management one of the fastest-growing job markets, compared to the overall job growth rate of 4%.

What are the responsibilities and roles of a Chief Human Resources Officer (CHRO)?

The job description needs to shift away from technical skills and towards managerial skills. Suddenly all those softer skills you’ve neglected and/or kept under wraps will need to emerge as you become an effective tech and digital business leader. CTO is an IT professional responsible for all technology systems, processes, software design and development within the company. Today, CTOs manage all technical aspects of a firm and guide employees on developing the right products and technology that support the firm’s needs.

  • Following that, Chief Technology Officers must manage, coordinate, and encourage team members.
  • You need to recruit an experienced specialist performing CTO functions and responsibilities in the short term.
  • Instead of coding, these CTOs shape the technology strategy and manage the programmers in their organizations.
  • What they can’t do is stay focused on development work, which needs to the team they’re now in charging of building, managing and motivating.

Because nearly every existing role will be affected by generative AI, a crucial focus should be on upskilling people based on a clear view of what skills are needed by role, proficiency level, and business goals. Training for novices needs to emphasize accelerating their path to become top code reviewers in addition to code generators. Similar to the difference between writing and editing, code review requires a different skill set. Most tech organizations are on a journey to a product and platform operating model.

Learn about technology

The other approach is to “bring data to the model,” where an organization can aggregate its data and deploy a copy of the large model on cloud infrastructure. Both approaches achieve the goal of providing access to the foundation models, and choosing between them will come down to the organization’s workload footprint. Taker—uses publicly available models through a chat interface or an API, with little or no customization. Good examples include off-the-shelf solutions to generate code or to assist designers with image generation and editing . This is the simplest archetype in terms of both engineering and infrastructure needs and is generally the fastest to get up and running. These models are essentially commodities that rely on feeding data in the form of prompts to the public model.

cto roles and responsibilities

They may also earn several certifications in development, programming, database administration or other related fields. In a newly conceived startup, it is common for the CTO to be responsible for all things technology-related. You can expect the CTO to help you figure out the technical feasibility of your business idea and how you can achieve it with limited financial capital. For someone whose entire job can be summarised as ‘technology leader’, technical strategy and advisory is perhaps the most fundamental responsibility that rests on their shoulders. The CTO represents the external face of a company, which requires them to have an open and engaged relationship with vendors, customers, investors and partners. RubyGarage can take responsibility for all the tasks of a CTO and guide your tech startup from inception to domination.

Chief Technology Officer (CTO): The Definition

The job of CTO is thinking up a technology stack, offering financial suggestions, and generally striving to improve the digital product. The CTO role on such a step is more of a tech visionary, HR professional, and team leader than a full-fledged developer. A chief technology officer is an executive who is responsible for the management of an organization’s research and development (R&D) as well as its technological needs. In this IT-intensive business landscape, a chief technical officer wears a lot of hats to manage the organization effectively.

Think of it as a hybrid of corporate strategist, human resources expert, team manager, and highly qualified developer. While no two software companies are alike, one or more of the following CTO duties will likely feature in your job description. Depending on your management style, background, and strengths, you may grow into these naturally or fill the need using the company resources. It is found in businesses that do not look to the technology teams for thought leadership.

What are the Chief Technology Officer’s key responsibilities?

Of course, a CTO may not need to fulfil each of these tasks personally; it largely depends on the size of the startup and the number of developers on the team. However, skills of a software architect are essential for CTOs of tech startups. If a CTO doesn’t have these skills, they won’t be able to make wise decisions related to application architecture and infrastructure.

The Onion Architecture : part 1 Programming with Palermo

The UI can’t function if business logic isn’t there. Business logic can’t function if data access isn’t there. I’m intentionally ignoring infrastructure here because this typically varies from system to system. We often don’t keep systems up-to-date because it’s impossible to do.

Yes, because some purely functional approaches cannot beat imperative ones when it comes to resource usage. This is an example structure similar to the one I use on my Symfony applications in my current company. It’s not perfect but after some years using the Onion structure we’ve made some changes to make it more evident where to put everything.

On the homepage I have a HTML action that calls a service and checks a database, so its running on every page view. Now, what about this thing called object scope or lifetime? Again, this is where the DI container steps in. Almost all of them have a lifetime model that allows for a “per HTTP request” lifetime.

In terms of unit testing, what you want to do is create mocks of your repositories. Again, it doesn’t matter whether you use code-based or edmx-based modeling. The repository is an abstraction of the data layer, so what you use behind the data facade is irrelevant to your unit testing code.

The circles represent different layers of responsibility. In general, the deeper we dive, the closer we get to the domain and business rules. The outer circles represent mechanisms and the inner circles represent core domain logic. The outer layers depend on inner layers and the inner layers are completely unaware of outer circles.

It started in CompSci sort of in parallel with Bob Barton’s B5000 designed for ALGOL, the work of Dijkstra, McCarthy’s LISP, Hamilton’s USL, and so on. They each came up with abstract ways to specify or implement programs for greater correctness, readability, safety, and composition. Using provers, compilers, or manual work, these would be converted into specific code at lower levels or final, machine level in ways intended to preserve high-level properties. Dijkstra went furthest in THE where the did hierarchical layers that were loop free. In parallel, there was a group trying to figure out how to compile Monte Carlo simulations on their computers in a way that was easy to specify. SimScript, a RAND language, was a discrete, event simulation tool that came out with many similarities to emerging Simula and OOP.

Application Layer Rules

In the Onion Architecture, the dependencies are always pointing inwards. The inner layer is the Domain Model and the outer one is the Infrastructure layer, which takes care of communicating with the external world. In Domain Driven Design, the Domain Model represents the processes and rules of your application and its main business, is the central and most important part of your application. Another important aspect is that this leads to a high risk of change. A change in one layer can potentially affect most functionalities as all mechanisms are shared horizontally. It leads to procrastination, meetings “Can I do it?

This gets even more interesting when there are multiple processes making up a single software system. Honestly, it’s not completely new, but I’m proposing it as a named, architectural pattern. Patterns are useful because it gives software professionals a common vocabulary with which to communicate. There are a lot of aspects to the Onion Architecture, and if we have a common term to describe this approach, we can communicate more effectively. Divide the application into different modules/projects each responsible for a layer in onion architecture.

A Web UI could be replaced with a console UI, for example, without changing the business rules. The business rules can be tested without the UI, Database, Web Server, or any other external element. Your articles are well organized with deep details. I am salute your time and efforts to share articles.

Domain Driven Design and The Onion Architecture

Check out Rowan Millar’s EF testing framework for help with this. In terms of implementation, I would place it in a separate assembly that can be referenced both by client and services. That way, you can validate on both ends with the same logic. You’ll want to use dependency injection to wire up the concrete implementation of the validation interface.

To do this, right-click the WebApi Project and go to properties. In the Build Tab enable the XML Documentation file and give an appropriate file name and location. I have added the XML file to the root of the API Project. The presentation layer is where you would Ideally want to put the Project that the User can Access. To maintain structural Sanity in Mid to Larger Solutions, it is always recommended to follow some kind of architecture.

Similar to Onion architecture (

The business rule is a valid artist or a valid album response has at least five images, something like that. That could be the expression in English of your rule. Them being circular has nothing to do with what are they representing. They are showing off the idea of hiding implementation through abstracting it. This is the exact same concept that both of these photos are showing.

  • That way, you can validate on both ends with the same logic.
  • If i still have them in the same project, that leaves the core of the entire application dependent on EF which i think is something Onion Arch is trying to solve.
  • Onion Architecture uses the concept of layers, but they are different from 3-tier and n-tier architecture layers.
  • I went through your articles and I can say ur aticles are one of the best.
  • It has access all the inner layers but most operations should go through the API, one exception being domain interfaces with infrastructure implementations.
  • The Presentation layer SHOULD only know about the Application or DomainModel layers and nothing about the Infrastructure one.

Application services also referred to as “Use Cases”, are services responsible for just orchestrating steps for requests and should not have any business logic. Application Services interact with other services to fulfil the client’s request. Let’s consider the use case to create an order with a list of items.

What are Some Problems with Onion Architecture?

We first need to calculate the price including tax computation/discounts, etc., save order items and send order confirmation notification to the customer. Pricing computation should be part of the domain service, but orchestration involving pricing computation, checking availability, saving order and notifying users should be part of the application service. The application services can be only invoked by Infrastructure services. It refers to the business knowledge that our software is trying to model.

Infrastructure Layer Rules

I have to say, I got a couple of examples of what people wanted to turn into an Onion Architecture. An ORM maps between the lower level relational semantics and higher level object semantics. It’s – maybe – a backdrop to explain why I felt a need to thank you for your choice of words with so many words. I remember there was another in this tutorial that shared more with the image in this post. You would be able to see the static applicative structure as far as the next monadic bind, which lets you do interesting types of optimization, e.g.
