Name some ways VCS systems help in software development.
- Keep records of changes
- Allow collaborative development
- Know who made changes to what
- Revert changes
- Build/release management
Centralized VCS
- Commit directly to remote
- Server has main copy
- Ex: Subversion
Distributed VCS
- Commit locally, push and pull to remotes
- No one has main copy
- Ex: Git
What are the advantage of DVCS over Centralized VCS?
- Can commit locally and push once you're ready
- Don't need internet connection to commit

Flexibility
Measure of how adaptable to 'reasonable' changes in a component is
Reusability
How usable a component is in
related applications without modification
Robustness
How well the component will
recover from anomalous events
