The Software Development Life Cycle (SDLC) is a framework defining tasks performed at each step in the software development process. It is a theoretical topic with high scoring potential.
1. Phases of SDLC
Standard phases include:
- Requirement Gathering and Analysis: Defining what needs to be built.
- Design: Defining the system architecture (Hardware and Software requirements).
- Implementation (Coding): Translating the design into code.
- Testing: Finding and fixing bugs (Unit, Integration, System, and Acceptance testing).
- Deployment & Maintenance: Releasing the software and applying updates/patches over time.
2. Popular SDLC Models
- Waterfall Model: A linear, sequential approach. You must finish one phase before starting the next. Difficult to accommodate changes late in the process.
- Agile Model: An iterative and incremental approach. Emphasizes flexibility, customer collaboration, and delivering small working pieces of software rapidly.
- Spiral Model: Combines elements of design and prototyping-in-stages, with a strong emphasis on risk analysis.
Final Thoughts
Mastering the concepts discussed above is a stepping stone towards your ultimate goal. Remember that consistency is key. Keep revising the core topics, practice as many questions as you can, and always analyze your mistakes to ensure continuous improvement.
