PostgreSQL, REST API's and Rapid Application Development for Legacy Data
summary
Demonstrates migrating diverse legacy data and apps into Postgres, exposing a working Postgres REST API and generating CRUD web/mobile clients with the Java-based CUBA platform and DBeaver for schema and view work. Real migrations keep COBOL and Access logic running while adding REST; converting hot COBOL paths to SQL/Java cuts run times from hours to seconds (examples show 2 hours → ~10–20 seconds). Generated code runs and is editable in Eclipse.
