The worldwide database standard
DBASE IV is a database application. With the dBASE IV connector, the integration platform can read and write dBASE IV files. The primary data file usually has a.DBF extension and the memo file usually has a.DBT extension. DBASE files are structured; for example, both the data and the file structure are stored inside the primary data file. DBASE IV UDF and Procedure Library.
