Introduction to Web Developent.

 

ü Web Development is the practice of developing websites and web apps that live on the internet.

ü Web development is the work involved in developing a Website for the Internet (World Wide Web)

ü There are two broad divisions of web development – front-end development (also called client-side development) and back-end development (also called server-side development).

 

ü Front-end development: Front end development refers to constructing what a user sees when they load a web application – the content, design and how you interact with it. This is done with three codes – HTML, CSS and JavaScript etc.

 

ü Back End development: Back-end development controls what goes on behind the scenes of a web application. A back-end often uses a database to generate the front-end. Back-end scripts are written in many different coding languages such as PHP, ASP.NET, Perl, Java, Python etc.

 

ü Full Stack Development: A full stack developers understand both front and back end strategies and process, which means that they are perfectly positioned to oversee the entire process.

What is Requirement Analysis in Software Engineering?

 Requirement Analysis is a fundamental phase in the Software Development Life Cycle (SDLC) that involves identifying, analyzing, documenting, and validating the needs and expectations of users or stakeholders for a new or modified software system.

Purpose of Requirement Analysis:

• Understand what the client truly wants

• Define the scope of the software

• Identify functional and non-functional requirements

• Lay a strong foundation for system design and development

• Avoid misunderstandings and costly rework later

Purpose of Requirement Analysis:

• Understand what the client truly wants

• Define the scope of the software

• Identify functional and non-functional requirements

• Lay a strong foundation for system design and development

• Avoid misunderstandings and costly rework later

Types of Requirements

1. Functional Requirements:

   • Describe what the system should do.

   • Examples:

     • User login

     • Data entry

     • Report generation

2. Non-Functional Requirements:

   • Define how the system should perform.

   • Examples:

     • Performance

     • Security

     • Usability

     • Reliability

3. Domain Requirements:

• Specific to the industry or domain (e.g., banking, healthcare)

• Might include regulations, standards, or constraints

Process of Requirement Analysis:

1. Requirement Elicitation (Gathering):

   • Techniques: Interviews, questionnaires, observations, brainstorming

   • Stakeholders: Clients, users, business analysts, developers

2. Requirement Analysis and Negotiation:

   • Clarify and resolve conflicts in requirements

   • Prioritize features

3. Requirement Specification:

   • Create documents such as Software Requirements Specification (SRS)

   • Should be clear, complete, consistent, and testable

4. Requirement Validation:

   • Ensure requirements meet the stakeholder’s needs

   • Techniques: Reviews, walkthroughs, prototyping

5. Requirement Management:

   • Handle changes in requirements throughout the project
