Source Code Management (SCM) encompasses tools and practices for tracking and controlling changes to source code. It facilitates collaboration, versioning, branching, merging, and conflict resolution, enabling efficient and robust software development. SCM supports auditability, reproducibility, and governance, aligning with compliance, quality, and security requirements. Tools like Git, Mercurial, and Perforce provide SCM capabilities, integrating with IDEs, build automation, and code review platforms. SCM is foundational to Agile, DevOps, and CI/CD practices, fostering innovation, agility, and integrity in modern software engineering.


Use Cases

Version Control and Code History

  • Objective: To maintain a record of changes to the codebase, allowing easy rollback to previous versions.
  • Scope: Storing code versions chronologically in a repository using Git, Mercurial, or SVN.
  • Advantage: Enables tracking of modifications, facilitating debugging and auditing.

Branching and Merging

  • Objective: To allow parallel development tracks without interfering with the main codebase.
  • Scope: Creating branches for feature development, bug fixes, or experiments, and merging them back into the main branch once completed.
  • Advantage: Enhances collaboration and accelerates development cycles by enabling simultaneous work streams.

Code Review and Collaboration

  • Objective: To streamline the process of reviewing code changes before they are integrated into the main codebase.
  • Scope: Utilize pull requests or merge requests for team members to review, comment, and approve changes.
  • Advantage: Improves code quality, encourages knowledge sharing, and minimizes errors.

Automated Builds and Testing

  • Objective: To automatically compile and test code from the repository to verify its integrity.
  • Scope: Integrate the source code management system with CI/CD tools to trigger automated builds and tests upon code commits.
  • Advantage: Offers immediate feedback on code quality, reducing the chances of buggy code making it to production.

Access Control and Security

  • Objective: To manage who has access to the code and what they can do with it.
  • Scope: Implement role-based access control, secure repositories with SSH keys, and enforce multi-factor authentication.
  • Advantage: Protects intellectual property, maintains code integrity, and ensures only authorized personnel can modify the codebase.
