IBM begins the System/R project in 1974 to develop SEQUEL, or Structured English Query Language. The language is based on E. F. Codd's relational database model and is designed to manipulate and retrieve data. The language is rewritten in 1977 to include multi-table and multi-user features. The revised system is briefly called SEQUEL/2 but later renamed SQL for legal reasons.
