Source Code Management (SCM) is a system that helps track and manage changes to source code, enabling developers to collaborate efficiently and maintain a history of the software development process.A key feature in SCM is branching, which allows developers to work on separate features or fixes without disrupting the main codebase, and merging these changes back into the primary branch once the work is complete.Tools like forking allow developers to create copies of repositories to work independently, while rebasing is used to integrate changes while maintaining a linear project history.Conflicts can occur during merges if changes overlap, requiring developers to manually resolve them.Checkout enables developers to switch between different branches or versions of the code, and the staging area helps organize changes before committing them.

Source Code Management (SCM) is a system that helps track and manage changes to source code, enabling developers to collaborate efficiently and maintain a history of the software development process. At its core is version control, which allows developers to track changes to the code over time and revert to previous versions when needed. This is usually done through a repository, a central location where all code is stored and tracked. Developers make commits, or snapshots of changes, with each commit representing a unique point in the project’s history. A key feature in SCM is branching, which allows developers to work on separate features or fixes without disrupting the main codebase, and merging these changes back into the primary branch once the work is complete. Conflicts can occur during merges if changes overlap, requiring developers to manually resolve them. SCM systems also offer tagging, which is used to mark specific points in history, such as releases or milestones. Additionally, pull requests or merge requests allow team members to propose and review changes before they are merged into the main codebase. Checkout enables developers to switch between different branches or versions of the code, and the staging area helps organize changes before committing them. Tools like forking allow developers to create copies of repositories to work independently, while rebasing is used to integrate changes while maintaining a linear project history. Hooks are scripts that automate tasks, such as running tests before committing code. Together, these SCM concepts ensure that teams can manage code efficiently, collaborate effectively, and maintain a structured development process.
