Jet Propulsion Laboratory Display Information System

The Jet Propulsion Laboratory Display Information System (or JPLDIS) is a file management program written in FORTRAN. JPLDIS is important because it was the inspiration and precursor to dBASE, arguably one of the most influential DBMS programs for early microcomputers. == History == In the late 1960s, Fred Thompson at the Jet Propulsion Laboratory (JPL) of the California Institute of Technology (Caltech) was using a Tymshare product named RETRIEVE to manage a database of electronic calculators.
