Migrations are a way to incrementally update the database schema to keep it in sync with the entity model while preserving existing data.
Benefits:

• Version control: Track database schema changes
• Team collaboration: Share schema changes across team
• Deployment: Apply changes to different environments
• Rollback: Undo changes if needed
• Data preservation: Update schema without losing data

# Add migration
dotnet ef migrations add InitialCreate
