RETRIEVE is a database management system (DBMS) offered on Tymshare's systems starting in August 1971. It was written in Tymshare's own SUPER FORTRAN on the SDS 940. It offered basic single-file, non-relational database functionality using an interactive programming language. It is one of the earliest examples of software as a service (SaaS).
RETRIEVE was highly influential and spawned a number of relatively direct clones. Wang Laboratories's RECALL on the Wang 2200 minicomputer was almost identical to RETRIEVE, to the point the differences were detailed in a single page. JPL made a version known as JPLDIS for the UNIVAC 1108 in 1973 that was also very similar.
Wayne Ratliff, a contractor at JPL for many years, was inspired by JPLDIS to port it to the IMSAI 8080 to manage his football pool, later releasing it commercially as Vulcan for CP/M in 1979. Ashton-Tate licensed Vulcan and re-released it as dBASE II in 1980, which sparked the microcomputer database market. Most of RETRIEVE's original syntax remains unchanged in dBASE and the many xBASE clones that survive into the 21st century.
