Best Implementation Practices for Discoverer

Other reporting tools such as MSAccess, ODBC and SQLPLUS have the inherent ability for an enduser to have direct access to tables for update, deletes, etc. Easily managed via the use of Oracle Roles. Security is regulated at the database level a ...

Multiparadigm Design of a Simple Relational Database
