On-line work of Mediator server on SQL database

What it means is that all commands executed by xBase applications immediately find themselves reflected in SQL database. This feature is crucial because some RDD drivers for SQL bases work on a local copy of the data taken from the server, which visibly lowers the affectivities (the necessity of making a local copy), and creates fundamental problems with work synchronization of many applications. When using such a driver, the application should be rewritten form a scratch.
