What are the different version control systems used in the SDLC?

There are several version control systems used in the Software Development Life Cycle (SDLC). Some of the commonly used version control systems include:

1. Git: Git is a distributed version control system that allows multiple developers to work on a project simultaneously. It provides features like branching, merging, and tracking changes, making it popular among software development teams.

2. Subversion (SVN): SVN is a centralized version control system that tracks changes to files and directories over time. It allows multiple developers to collaborate on a project and provides features like branching, tagging, and merging.

3. Mercurial: Mercurial is a distributed version control system similar to Git. It offers features like branching, merging, and tracking changes. It is known for its simplicity and ease of use.

4. Perforce: Perforce is a centralized version control system commonly used in large-scale software development projects. It provides features like branching, merging, and file locking to ensure smooth collaboration among developers.

5. Team Foundation Version Control (TFVC): TFVC is a centralized version control system provided by Microsoft's Team Foundation Server (TFS). It offers features like branching, merging, and tracking changes, and is commonly used in Microsoft-centric development environments.

These are just a few examples of version control systems used in the SDLC. The choice of version control system depends on factors like team size, project requirements, and development workflow.
