Somewhere I have an vintage 1970s ACM survey of DBMSs that cites a paper or article about GIRLS.

I just re-read Sundeen's Datamation article (below) over the weekend and noticed the genealogy of GIRLS.

There was a disagreement about ownership of intellectual property, but I'm not sure it was public knowledge. TRW was involved in a lawsuit with Microdata. The settlement (1974) paid to TRW was an amount that was equal to one GIM license for a year.

I'm not sure. He was talking about retiring during the '70s. Google shows he was Cal Tech class of 1943.



Donald H. Sundeen's 1968 article describes the evolution of general purpose software. Sundeen had worked on data management systems at Informatics and Scientific Data Systems for eight years. His article also discusses earlier systems such as 9PAC developed by SHARE and the general purpose file-handling routines developed at GE's Hanford Plant in 1957.
