Burlington, Massachusetts-based Ontologic Inc’s object-oriented Ontos database is to get a front-end design and code-generation tool courtesy of a five-year deal it has struck with Associated Design Technology, Westborough, Massachusetts. Ontologic has made what it calls a significant financial commitment to Associated for its Ptech software, which runs on Silicon Graphics Inc workstations and generates C++ version 2.0 application code when running in conjunction with Ontos. Ptech users do not need to know C++ or SQL, as database objects are represented by icons, and users build relationships among the icons to build applications. A joint Ptech/Ontos product will be out in December, the same time that a version of Ptech for Sun-3 and Sun-4 workstations is scheduled for introduction. The Ptech/Ontos software will cost from $32,500 to $50,000 for Sun and Silicon Graphics workstations, with a DEC version following next year.
