SDLC stands for Software Development Life Cycle. The SDLC is a process or culture used in software industry to design, develop, test and deploy software applications. The SDLC provides a systematic approach to software development, ensuring that all necessary steps are followed to deliver a high-quality product.
Here are the typical phases of SDLC:
Planning/Requirement Analysis:
- In this phase, the project goals are defined, and the requirements are gathered. Stakeholders work together to specify the software's functionality, features, and constraints.
System Design:
- Based on the requirements, the software’s architecture and design are created. This phase involves both high-level design (overall structure) and low-level design (specific components and interactions).
Implementation (Coding):
- In this phase, the actual coding takes place. Developers write the software based on the design specifications.
Testing:
- After the software is developed, it undergoes various tests to find and fix bugs or issues. This phase ensures the product is functional, reliable, and meets the specified requirements.
Deployment:
- Once the software passes testing, it is deployed to the production environment where users can start using it.
Maintenance:
- After deployment, the software enters the maintenance phase. This includes fixing bugs, updating features, and ensuring the software stays up to date with changing needs or technologies.
Different SDLC models (like Waterfall, Agile, Spiral, etc.) can be used to execute these phases, depending on the project requirements and goals.
