    System R is a database management system that was built as a research project at IBM San Jose Research (now IBM Almaden Research Centre) in the 1970’s. System R introduced the SQL language. System R evolved into SQL/DS that later became DB2. Oracle released the first commercial SQL database in early the 1980’s based on the System R specifications.
