Corporate history[edit]

Founded in 1965, Computer Corporation of America (CCA) was a computer software and database systems.[1] with offices in Technology Square, Kendall Square, Cambridge, Massachusetts.[3]

Their primary database product, first deployed in 1972, was Model 204 (M204), which ran on IBM mainframes.[4]: 66 [5] It incorporates a programming language and an environment for application development.

CCA operated the ARPANET Datacomputer.

In 1992,[6] CCA purchased the System 1022 and System 1032 assets of Software House; these database systems were designed for Digital Equipment Corporation's PDP-10 and VAX systems, respectively.[7]

In 1984, CCA was purchased by Crowntek, a Toronto-based company.[8] Crowntek sold Computer Corporation of America's Advanced Information Technology division to Xerox Corporation in 1988.[9]

The balance of CCA was acquired by Rocket Software, a Boston-based developer of enterprise infrastructure products,[2] in April 2010.[10]
