Mediator Client

Mediator components are based upon xHarbour kernel. Apart from the above VCL components there are several low level classes which are used to access xHarbour kernel.

Using xHarbour kernel as a foundation for Mediator components enables nearly 100% compatibility between DBF-based applications and Mediator-based applications. See Low level interface for more information.
There are several possibilities here. The option which is most interesting for you will probably depend whether you are Clipper/xHarbour developer.
