 MEDIATOR for  Oracle
  Wind for Clipper's sail

Mediator for Oracle enables any CA-Clipper application to work in Oracle database environment. The Mediator allows to save the most valuable thing - thousands of tried-and-true lines of code while replacing the data storing methods, which are the weakest elements of CA-Clipper. Porting data to Oracle database means the end of problems with damaged indexes, tables that are too big or insufficient protection. Additionally using Mediator enables CA-Clipper programmers to use full capabilities of ORACLE server.

Mediator enables a quick and easy achievement of technological breakthrough in the software, requiring incomparably lower expenses than are traditionally associated with upgrading the software.

How does CA-Clipper/MEDIATOR application work?

Mediator is RDD driver. RDD standard (Replaceable Data Driver) is used with CA-Clipper tools beginning from version 5. After linking Mediator libraries, CA-Clipper application connects with MEDIATOR server communicating with Oracle database server, instead of the traditional reading of *.dbf files. CA-Clipper/Mediator application follows a client-server model: data processing (selection, index modification, sorting) is located on the server, while data presentation is located on workstations.

Information flow in MEDIATOR system

Mediator server can run on the computer with Oracle database installed, or it can communicate with a database located on another computer via SQL*Net software.

System architectures.
