# Desktop databases vendor-specific interface · access · 1999

Revision 1 (11 October 2026) · Modeled snapshot · through 8 October 2026.

All figures are research-informed estimates of analytical activity. Significant errors may remain; decimal places do not imply measurement precision.

6.29% of the full access layer.

[Desktop databases vendor-specific interface](https://history.columnar.tech/technologies/access/vendor-desktop.md): historical names and annual shares.

Local and departmental analytical execution in desktop database families, including dBASE, FoxBASE/FoxPro, Clipper, Paradox, FileMaker, and Microsoft Access. The pool counts reporting and analysis, not all licensed copies, data entry, or operational applications. SQLite has its own box. Queries passed through to a server are counted with that server; local desktop execution over another database’s tables uses federated native storage.

Connections below describe the whole Desktop databases engine. Access and storage mixes are estimated separately; they are not a joint interface-to-storage distribution.
