DEC has resolved the thorny issue of an SQL relational database for use with its Ultrix Unixalike by buying Ingres technology from Relational Technology Inc to use as the basis of what will become its own proprietary SQL database for Ultrix, promising that third party applications written for it will be portable to its own Rdb/VMS database, which is being bundled with VMS 5.0, and to other open systems. It is likely that it will bundle a run-time version the resulting product, for which no date has been given, with Ultrix, much to the annoyance of suppliers of rival databases such as Oracle Corp.
