Borland Database Engine Download4/17/2021
This presentation provides an introduction to the basic techniques for building database applications using Delphi or CBuilder.This presentation begins with a general overview of the heart of database development using the VCL, the Borland Database Engine.
![]() Use of non-VCL database development available in Delphi 5 is also addressed. From time to time you will also see the BDE referred to as IDAPI (Integrated Database Application Programming Interface). Several Corel products, including Paradox 8 for Windows and Quattro Pro also use it. In addition, by default, database applications written with these products use the BDE. In other words, Delphi uses the BDE, as well as those database application you write with Delphi. Consequently, one installation of the BDE can be used by two or more BDE-aware applications simultaneously. As a result, each individual VCL-based application is smaller in size that it would be if all data-accessing code needed to be linked into the executable. Furthermore, since two or more applications can share the same copy of the BDE loaded into memory, overall RAM usage is reduced when two or more BDE-aware applications are running simultaneously when compared to linking the code into each EXE. These include table and record locking, SQL construction, record updates, and basic IO, to mention a few. Borland Database Engine How To Access ItThe BDE permits you to concentrate on what data you want to access, instead of how to access it. Due to the BDE, your Delphi and C Builder applications can just as easily use data in dBASE or Paradox tables, files on a remote database server, and files supported by ODBC (Open DataBase Connectivity) drivers. Fortunately, you almost never need to call any of these routines directly. Instead, you use the BDE through the VCLs data access components, which are found on the Data Access page of Component Palette. These components encapsulate calls to the BDE API, providing you with a much simpler interface. However, if you have special data needs not provided by these components, you can use the BDE API directly. As you can see, the BDE is a software layout that lies between BDE-aware applications (Delphi and the database applications you create with it) and the sources of your data. It also shows that the BDE can access local tables, such as Paradox and dBASE directly. Connecting to MS Access and Fox Pro tables requires that you already have the DAO (Data Access Objects) DLLs from Microsoft installed). For the best performance in connecting to a remote database server, such as Oracle, MS SQL Server, InterBase, and so forth, you use Borland SQL Links drivers. These native language drivers are provided in the Delphi clientserver and Delphi Enterprise editions. In addition, SQL Links drivers must use an additional network protocol to connect to the remote server.
