Primus Communications Corp, Seattle, Washington, has established a joint venture in Japan with Tokyo-based systems integrator Trans Cosmos Inc. The new company, Primus KK, will market Primus’s SolutionBuilder data capture client-server application software. SolutionBuilder accesses shared files and searches in databases for targeted data. Users can capture and re-use database components as they are created. SolutionBuilder is based on Versant Object Technology Corp’s object-relational database and runs under Solaris 2.4. Primus will convert the server to HP- UX and Windows NT before the summer. SolutionBuilder costs from $5,000 per concurrent user. SupportBuilder is the first in a series of products Primus is building in conjunction with the Customer Support Consortium, an organisation of hardware and software vendors that develop support systems. Primus is also developing an on-line database support service.
