Data Independence

Clarion achieves database independence with its built-in driver technology, which lets you access data from virtually any file system using the same set of Clarion language commands. Many file drivers are available and more are being added.

Before you can use a database driver, it must be registered. The database drivers in this package are pre-registered. See the User's Guide--Configuring the Environment for more information on registering add-on database drivers.

The Clarion language commands for accessing data are the same regardless of the file system you use; simply choose the appropriate file driver from the drop-down list in your Data Dictionary, then don't worry about it. The file driver translates the Clarion commands to the chosen file system's native format. The drivers read and write in the file system's native format without temporary files or import/export routines.
