Jan 17, 2024 · In 2002, the first mainstream multi-core processor was launched with Intel’s Pentium 4 7. For the first time, SQL engines could optimize multiple dimensions, between IO, query execution, logical plan, and physical plan for execution. Known as multi-core execution, could scale vertically much more efficiently.
The language, Structured English Query Language (SEQUEL) was developed by IBM Corporation, Inc., to use Codd's model. SEQUEL later became SQL (still pronounced "sequel"). In 1979, Relational Software, Inc. (now Oracle) introduced the first commercially available implementation of SQL. Today, SQL is accepted as the standard RDBMS language ...
