Siemens Nixdorf Informationssysteme AG is gradually fleshing out its approach to object-oriented technologies and after choosing Hewlett-Packard Co’s OpenView to develop a network management system, the parent company Siemens AG’s public communication networks and transmission systems unit has plumped for Objectivity Inc’s Objectivity/DB database in a deal worth around $1.8m to the Menlo Park, California-based outfit. Siemens will use Objectivity/DB in new telecommunications transmission systems. Objectivity’s German distributor, Micram Object Technology GmbH is providing Classify/DB, its Object Database Management Group-93-compatible object database schema definition language, which provides a bridge between graphical user interface class libraries with object databases for application development.
