This version, initially called SEQUEL (Structured English QUEry Language), was designed to manipulate and retrieve data stored in IBM's original quasi-relational database management system, System R, which a group at IBM San Jose Research Laboratory had developed during the 1970s.QL was one of the first commercial languages for Edgar F. Codd 's relational model, as described in his influential 1970 paper, A Relational Model of Data for Large Shared Data Banks.. Despite not entirely adhering to the relational model as described by Codd, it became the most widely used database language.
