Teradata Corp, Los Angeles is taking its challenging DBC/1012 back-end relational database management system, which harnesses scores of Intel 80386s for superfast parallel searching, into the Unix world – and has chosen Cambridge, Massachusetts-based Charles River Data Systems as its partner. The aim is to develop an extended client-server offering for the large systems market, and the first products from the partnership will be a Unix capability added to the DBC/1012, and a remote Data Base Computer capable of serving multiple clients, while acting as a client itself to the central DBC/1012. These two products are set for announcement in the spring. Until now, the DBC could serve clients but not other servers, Teradata notes, adding that the new agreement will lead to a layered architecture, within which a remote server can also be a host-client to the DBC/1012 and sees the combination enabling users to gain the advantages of both IBM’s Systems Application Archi tecture and open systems environments. Teradata says that it remains comm itted to Systems Applicati on Architecture principles and protocols but also int ends to integrate the Unix environment to integrate the islands of information found in large enterprises.
