Relational Technology Inc, Alemeda, California, is to launch a new version of its Ingres database next week, and says that it will use a totally reworked architecture, according to newly appointed UK managing director Hugh McCartney. Existing customers will be offered an easy upgrade, said McCartney, who also hinted that the company might be following the fashion of database firms and changing its name to Ingres, if trademark restrictions from the University of California at Berkeley can be circumvented.
