Git database architecture

Git’s operational logic is rooted in its underlying data structures rather than a mere collection of memorized commands.

Core Data Structures

  • commits: Snapshots representing the state of the project at specific points in time.
  • Branches: Pointers or references directed toward specific commits.
  • DAG (Directed Acyclic Graph): The mathematical framework that structures the relationships and flow between commits.
