DEVELOPER EXPERIENCE
|
|
================================================================================
|
|
|
|
BEFORE - New Developer:
|
|
1. Read 18 separate migration files
|
|
2. Figure out which patches apply to which tables
|
|
3. Mentally merge changes across multiple files
|
|
4. Trace forward references
|
|
5. Hope you didn't miss anything
|
|
|
|
AFTER - New Developer:
|
|
1. Read 5 logically grouped migrations
|
|
2. Each domain self-contained
|
|
3. All patches already incorporated
|
|
4. Clear dependency flow
|
|
5. Comprehensive README with diagrams
|
|
|
|
Time to Understand Schema: 2 hours → 30 minutes
