Explain Software Development Life Cycle (SDLC)

The Software Development Life Cycle (SDLC) is a systematic and structured approach to developing high-quality software that meets user requirements, is delivered on time, within budget, and is easy to maintain. It is a framework that guides software developers through the process of planning, designing, developing, testing, and deploying software products.

The typical SDLC process consists of the following stages:

Planning: This is the initial stage where the software development team defines the objectives, scope, and requirements of the software product. They also identify potential risks, constraints, and limitations, and define a project plan.

Analysis: In this stage, the development team analyzes the requirements and creates a detailed functional specification. This involves identifying the necessary features and functionalities, use cases, user interface design, and system architecture.

Design: In this stage, the development team creates a detailed design specification for the software product, including database design, technical architecture, and detailed specifications for each module.

Implementation: This is the stage where the actual coding of the software product takes place. The development team writes the code, integrates various modules, and performs unit testing to ensure that each module is functioning correctly.

Testing: In this stage, the development team conducts various testing activities such as integration testing, system testing, and user acceptance testing to ensure that the software product meets the requirements and is free from defects.

Deployment: This is the stage where the software product is released to the production environment, and end-users start using the software product.

Maintenance: In this stage, the development team performs various maintenance activities, such as bug fixing, software updates, and enhancements to ensure that the software product continues to meet user requirements.

The SDLC process can vary based on the specific software development methodology used by the development team, such as Waterfall, Agile, or DevOps. However, the core stages of planning, analysis, design, implementation, testing, deployment, and maintenance remain the same.
