Evolution of Database Use Cases
The discussion touches on the evolving use of databases, particularly whether they should serve merely as dump stores or integrate intelligent processing capabilities. Initially, stored procedures were commonplace, but preferences shifted towards keeping business logic within application layers, specifically Java. However, it became clear that complex operations often required closer integration with the database to avoid performance bottlenecks associated with transferring data back and forth. As a result, contemporary practices show a more nuanced approach, combining the strengths of both application logic and database processing.
