Data Structures > Data structures: overview

This topic is an overview of various data structures used by BDE or its drivers, and miscellaneous data structures defined in the Borland Database Engine (BDE) header file (for Borland C, this header file is called IDAPI.H, for C++Builder, it is BDE.HPP, and for Delphi it is BDE.INT). IDAPI.H.

These are the data structures most commonly used in BDE programming:
