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

0.5% of the full compute layer.

[Early relational databases](https://history.columnar.tech/technologies/compute/other-relational.md): historical names and annual shares.

Early commercial databases organized data into tables and supported relational queries. This is a pooled estimate of their reporting activity.

Connections below describe the whole Early relational databases 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 |
| --- | --- | --- |
| [Early relational databases vendor-specific interface](https://history.columnar.tech/technologies/access/vendor-other-relational.md) | 100% | 0.5% |

## Storage use within this engine
