[IBM relational (SQL/DS/Db2 lineage)](https://history.columnar.tech/technologies/compute/ibm.md): historical names and annual shares.

Connections below describe the whole IBM relational (SQL/DS/Db2 lineage) engine. Access and storage mixes are estimated separately; they are not a joint interface-to-storage distribution.

## Access use within this engine

| Option | Share of engine activity | Share of full access layer |
| --- | --- | --- |
| [IBM relational (SQL/DS/Db2 lineage) vendor-specific interface](https://history.columnar.tech/technologies/access/vendor-ibm.md) | 52.9% | 8.1% |
| [ODBC](https://history.columnar.tech/technologies/access/odbc.md) | 28.2% | 4.3% |
| [JDBC](https://history.columnar.tech/technologies/access/jdbc.md) | 12% | 1.8% |
| [Other language/portable APIs](https://history.columnar.tech/technologies/access/other-api.md) | 6.2% | 1% |
| [Python DB-API (other drivers)](https://history.columnar.tech/technologies/access/python.md) | 0.6% | <0.1% |

## Storage use within this engine

| Option | Share of engine activity | Share of full storage layer |
| --- | --- | --- |
