Information in this document applies to any platform.


Take a real life situation where some of Business Logic is implemented at Database Layer (Oracle) using PL/SQL Packages, Procedures, Functions with Cursors , Bulk Collect, Types, Nested Tables, etc.

What will be the impact of keeping all business logic at application side (Java) instead of Database Layer ?
