 MEDIATOR for SQL Anywhere
  Wind for Clipper's sail

Mediator for SQL Anywhere enables any CA-Clipper application to work in Sybase Adaptive Server Anywhere (SQL Anywhere) database environment. 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 RDBMS 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 Sybase Adaptive Server Anywhere.

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 with version 5. After linking Mediator libraries, CA-Clipper application connects with MEDIATOR server accessing data stored in SQL Anywhere, instead of the traditional *.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 work on the computer with Sybase SQL Anywhere database installed, or it can communicate with a database located on another computer using network libraries.

System architectures.

Profits gained from using Mediator
