Introduction
In a business intelligence and data warehousing solution, there is nearly always a need to enhance or add information to the solution. For this reason, a simple but functional user interface is always needed to support the requirements.
Oracle Application Express (APEX) is a robust, web-enabled design, development, and run environment, used to build custom applications within an Oracle database. APEX is shipped as part of an Oracle database, and is currently free. The tight integration with the Oracle database, ease of use, and cost make APEX ideal to build an automated solution to fill the data gaps.
