Go Up to Using BDE Index
Warning: The Borland Database Engine (BDE) has been deprecated, so it will not be enhanced. For instance, BDE will never have Unicode support. You should not undertake new development with BDE. Consider migrating your existing database applications from BDE to dbExpress. For information about migrating from BDE to dbExpress, see http://www.embarcadero.com/rad-in-action/migration-upgrade-center.
When using the BDE, your application uses a variation of the general database architecture described in Database Architecture. In addition to the user interface elements, datasource, and datasets common to all Delphi database applications, A BDE-based application can include
- One or more database components to control transactions and to manage database connections.
- One or more session components to isolate data access operations such as database connections, and to manage groups of databases.
The relationships between the components in a BDE-based application are illustrated in the following figure:
The following topics provide additional information about these components:
