Learn the basics of web development and get a high-level view of the web development landscape.

Become a Front-end Developer

This module encompasses everything from the basics of networks to the principles of front-end web development with HTML, CSS, and JavaScript. After taking this module, not only will we be comfortable learning any web technology, but we'll also have a better idea of what different technologies are out there and what we want to learn. We'll also become familiar with version control systems, which are a global industry standard.

Web Development: A Primer

## Introduction

The waterfall model is the first published model of the software development process, and it consists of representing the fundamental activities of specification, development, validation, and evolution as separate, sequential process phases.

## Principle stages
There are multiple stages involved in the waterfall model, and theoretically, every stage must be completed before the next one can be "cascaded" on to, which is why the model is referred to as the waterfall model. 

Each of the five stages depicted in the above diagram is described in more detail in the rest of the lesson.

### Analyse and define requirements 
The system’s intended services, potential constraints, and goals are established and then defined in detail. These requirements then serve as a product specification, according to which the website is then developed. 

### Design software
The design process entails allocating the requirements realized in the previous stage to different software components by establishing an overall system architecture. Software design involves identifying and describing the fundamental software system abstractions and the relationships amongst them that your website will require.

### Implement and test units
During this stage, the software design is translated to a set of programs or multiple program units. Unit testing involves verifying that each unit meets its specifications.

### Integrate units and test system
The individual program units are integrated and tested as a complete system to ensure that the software requirements have been met. After testing, the software system is delivered to the customer. In the case of your own website, you would deploy it at this point.

### Operation and maintenance
Normally (although not necessarily), this is the longest life cycle phase. The system is installed and put into practical use. Maintenance involves correcting errors that were not discovered in earlier stages of the life cycle, improving the implementation of system units and enhancing the system’s services as new requirements are discovered.
