Note for advanced developers

You can create new TOQBEngine descendants to work with any DataSet-oriented sources (for example - OCI engine etc.). If you create your own OQBEngineXXX - contact us to share it with the Delphi and C++Builder developers community. We will place your engine on our web-site. Please save the style of your engine-component's .dcr-icons and deploy your components as freeware with full source code. OQBuilder allows you to save and load query models. The OQBuilder query format looks like an ".ini file" and is defined (and may be customized by you) in procedure TQBForm.btnSaveClick (model saving) and procedure TQBForm.btnOpenClick (model loading).

The first limited public version of QBuidler for Delphi 1&2 was released in 1996.
