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.

2.285% of the full access layer.

[Sybase ASE vendor-specific interface](https://history.columnar.tech/technologies/access/vendor-sybase.md): historical names and annual shares.

The Sybase SQL Server lineage, later called ASE. This box counts its reporting and analytical workloads. The IQ analytical database is a separate product family.

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