Git Architecture Workflow
Git Architecture is an object database repository composed of three core DAG (Directed Acyclic Graph) node object types: Blobs (storing raw file data), Trees (mapping directory folder layouts), and Commits (storing snapshot metadata).
Real-world analogy: Files, Folders, and Logs
Blobs are document pages containing text. Trees are folders containing documents and nested folders. Commits are catalog envelopes recording folder structures and author details.
- Blob= Stores raw file content, stripped of name and permissions (keyed by SHA-1 hash).
- Tree= Maps directory layouts, linking blob hashes to file names.
- Commit= Stores parent tree hashes, author info, timestamps, and commit messages.
Git commands & actions explained
Real-world applications
Database Integrity
Ensures repository history is tamper-proof using SHA-1 hashing.
Space Optimization
Deduplicates identical files globally by sharing blob references.
Metadata Audits
Traces parent commit linkages back to original repository roots.

Git Workflow Metadata
Git is content-addressable! It retrieves objects based on content hashes, ensuring files with identical content are stored only once.
