Why Database Abstraction is Better
|
||
|
|
|
||
|
|
### Current Problems:
|
||
|
|
1. **Tight Coupling**: Auth services are hardcoded to `PgPool`
|
||
|
|
2. **Limited Flexibility**: Can't easily switch databases
|
||
|
|
3. **Maintenance Burden**: Database-specific code scattered throughout
|
||
|
|
4. **Testing Complexity**: Hard to test with different databases
|
||
|
|
5. **Vendor Lock-in**: Forced to use PostgreSQL for auth features
|
||
|
|
|
||
|
|
### Benefits of Database Abstraction:
|
||
|
|
1. **Loose Coupling**: Services depend on traits, not concrete types
|
||
|
|
2. **Database Flexibility**: Easy to switch between SQLite, PostgreSQL, MySQL, etc.
|
||
|
|
3. **Better Testing**: Can use in-memory databases for tests
|
||
|
|
4. **Cleaner Code**: Single interface for all database operations
|
||
|
|
5. **Future-proofing**: Easy to add new database backends
