Because BDE offers local caching, it has the capability to let your applications run even faster than if you had used direct database-dependent SQL calls. The BDE uses the Borland SQL Links DLL to interface with the client-side drivers provided by SQL database vendors. SQL Links completely insulates the BDE from dependencies on networking or driver DLL idiosyncrasies. It is only SQL Links that talks to the client-side driver of your DBMS, and only this driver has anything to do with the network. Simple database user interfaces can be built visually in a matter of hours or even minutes.
Complex systems requiring queries are just as easy.
Applications requiring queries with variable parameters are still much easier with the VDBT components than ever before. Because everything has evolved to a visual environment, almost everything you do will be easier to accomplish and take less time. The simple hierarchy of the VDBT components allows you to programmatically make changes to the system at any level. You can control the low level database using a TDatabase object. Individual tables can be manipulated using TTable objects.
