Source Control Management

  • Source Control Management (SCM), also known as Version Control or Revision Control, is a systematic approach to tracking changes and managing versions of source code and other files in a software development project.
  • The primary purpose of SCM is to enable collaboration among developers, facilitate the organization and tracking of changes, and ensure the integrity and stability of the codebase over time.Here is a detailed description of key aspects of Source Control Management:
  • A repository is a central database or storage location that holds the entire history of a project, including all versions of files and their associated metadata.
  •  Repositories can be local (on a developer’s machine) or remote (on a server).
  • Versioning involves assigning unique identifiers (usually numbers or hashes) to different versions of files within the repository.Each version represents a snapshot of the project at a specific point in time.
  • A commit is a fundamental operation in SCM. It is the act of saving changes to the repository. Each commit includes a set of changes made to files, a commit message explaining the purpose of the changes, and a reference to the previous version.
