Version Control When Developing a Software Engineering Solution

Version control

• Tracking changes + revert to previous states
• Collaborative
• Branching

Core concepts

Tracking changes and reverting

• Every change is saved as a commit with a message describing what changed and why
• Allows reverting to any previous state if a bug is introduced
• Provides a full audit trail of who changed what and when

Collaboration

• Multiple developers can work on the same codebase simultaneously
• Changes are merged and conflicts are resolved systematically
• Remote repositories (e.g. GitHub, GitLab) allow distributed teams to share code

Branching

• Branches allow separate lines of development (e.g. feature branches, bug fix branches)
• Main/master branch holds stable, production-ready code
• Feature branches are merged back via pull requests after review
