Borland’s Delphi© makes the construction of Windows applications easier than ever. In particular, the Borland Database Engine (BDE) offers enormous power with great ease. Sometimes, however, the full might of the BDE is overkill. Wouldn’t it be better for your simple projects to use a simple tool, one that could be distributed inside your EXE and didn’t require enormous DLLs to function?
The QDB components for Delphi offer fast, indexed access to a flat-file database of variable-sized items. QDB is quick, easy to use, and comes with full installable help. It’s also free! Caveat! It is some years since these components were developed and they probably won’t function beyond D5 without a lot of tweaking. They are–regrettably–also unsupported. Nevertheless I hope you find them useful in some way.
Also available are the usual demonstration applications written to show the power and ease of QDB. There is a simple address book, a rewrite of Borland’s Animals demo, and a rudimentary knowledge-base system. They each come with full source code.
