What are the different phases of the SDLC?

The Software Development Life Cycle (SDLC) consists of several phases that are followed in the development of software. These phases are as follows:

1. Requirement Gathering and Analysis: In this phase, the software requirements are gathered from the stakeholders and analyzed to understand the scope of the project. This involves identifying the goals, objectives, and constraints of the software.

2. System Design: Once the requirements are gathered, the system design phase begins. This phase involves creating a high-level design that outlines the architecture, components, and interfaces of the software system. It also includes designing the user interface and database structure.

3. Coding: In this phase, the actual coding of the software takes place. The design specifications are translated into a programming language, and the software modules are developed. This phase requires expertise in programming languages and coding standards.

4. Testing: After the coding phase, the software is tested to ensure that it meets the specified requirements. This includes unit testing, integration testing, system testing, and acceptance testing. Bugs and errors are identified and fixed during this phase.

5. Deployment: Once the software passes all the testing phases, it is deployed to the production environment. This involves installing the software on the end-user's system and configuring it to work properly. User training and documentation are also provided during this phase.

6. Maintenance: After the software is deployed, it enters the maintenance phase. This phase involves fixing any issues or bugs that arise in the software, as well as making enhancements or updates based on user feedback or changing requirements. Regular maintenance and support are provided to ensure the software's smooth operation.

These phases of the SDLC are followed in a sequential manner, with each phase building upon the previous one. However, it is important to note that the SDLC can be iterative or agile, where the phases are repeated or overlapped to accommodate changes and improvements throughout the development process.
