Working with Tables in Other Database File Formats

Access and other Microsoft programming platforms, such as Visual Basic 6.0, dominate today's database front-end development market. Thus the importance of Access's import/link support for legacy desktop database files has decreased as use of Paradox, dBASE, and FoxPro have declined, especially for new projects.

Conventional desktop database development applications maintain each table in an individual file. Each file contains a header followed by the data. A header is a group of bytes that provides information on the file's structure, such as the names and types of fields, number of records in the table, and file length. When you create a table file in dBASE, Visual FoxPro, or Paradox, for example, the file contains only a header. As you add records to the file, the file size increases by the number of bytes required for one record, and the header is updated to reflect the new file size and record count.
