Essentially, I think the discussion about the full stack is also a kind of argument relating to the all-rounder and expert in the IT industry, and debate on the depth and breadth of development skills.

We hear people talking about front end and the back end or sometimes the client side and the server side. Frontends are about presenting the data to the users. This is where the users access the web through the browser. So, we would be using technologies like HTML, CSS and JavaScript to target the end users.

On the other hand, the backend is more concerned with the business logic and the data aspect of a web application. This might be implemented in one of several languages.

Our 3-tier Architecture

We often hear people talking about the three-tier architecture for web development. Implementation in this approach is a common client-server software architecture pattern. The entire development is divided into three layers:

  • The presentation layer, which is concerned with UI related issues and how to present the data to the end user
  • The business logic layer which is more concerned with data validation and processing the data in order to generate information for the users
  • The data access layer which deals with data persistence and storage of data behind the scenes

Let’s look at what is implemented in each of these three layers in more detail. The business logic layer is implemented in a server where we use languages like Ruby, Python, C++, Java or The server talks to a back-end database management system to exchange data, which, in turn, generates the front-end display of data to the user by server-side rendering of the HTML, CSS and JavaScript.

Ophel specialist of each these three layers

This is the traditional approach that has been used successfully in web development. Now, in this approach we have specialists in each of these three layers. We have a front-end specialist would be well versed in HTML, CSS, and JavaScript.

We have the backend specialists, we would be well-versed in server-side implementation say for example several languages used for server-side implementation.

We would have a data specialist who would be mostly concerned with the data basis and data persistence aspect of the web development.

There is an increasing trend towards full stack web development, which is used for implementation over the entire stack. You could be having the front end implemented as a Single Page Application (SPA) using one of the JavaScript frameworks like AngularJS. The server-side could be implemented using technologies like Node.js, which again depend on JavaScript.

The data access or data storage part is implemented using technologies like MongoDB, which works based on storing JSON data and serving up information in the form of JSON. JSON has become the standard format for data interchange among the three layers.

Delivering a REST API so that you can target multiple platforms. Through the REST API, the server is serving up data in the form of JSON which can then be rendered either on standard web browser or on a mobile device using one of the multi-platform hybrid mobile application development environments.

Basic design ability

Most of the articles or discussions about the full stack developer are rarely related to the design requirements. But I think the design skill is very important, the principle and skill of basic prototype design, UI design, UX design are also needed to understand.
