# IBM relational (SQL/DS/Db2 lineage) 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. Layer: compute. Values cover the years in which this category appears in the public timeline. Absence is not proof of zero use. ## Names and inspection notes ### 1982: IBM SQL/DS This category is shown in the compute layer. ### 1983–2026: IBM relational (SQL/DS/Db2 lineage) This category is shown in the compute layer. ## Annual estimates | Year | Name in this year | Share of full compute layer | Connections and details | | --- | --- | --- | --- | |
