Database Compatibility for Oracle means that an application runs in an Oracle environment as well as in the EDB Postgres Advanced Server (Advanced Server) environment with minimal or no changes to the application code.
Developing an application that is compatible with Oracle databases in the Advanced Server requires special attention to which features are used in the construction of the application. For example, developing a compatible application means selecting:
SQL statements that are compatible with Oracle SQL
System and built-in functions for use in SQL statements and procedural logic that are compatible with Oracle databases
Stored Procedure Language (SPL) to create database server-side application logic for stored procedures, functions, triggers, and packages
