Sybase Inc has announced a relational database management system specifically designed for on-line applications. The Berkeley, California company says that the relational database manager – also called Sybase – is the first SQL-based product for DEC VAXes under VMS, and Sun Microsystems’ workstations running Unix, to provide the capabilities required for on-line applications: high-volume performance, DBMS enforced data integrity, high availability, distributed database management and window-based application development tools. It is claimed that Sybase provides users and developers of on-line applications with the performance of a transaction-based file system and the ease of use, flexibility and maintainability of a SQL-based relational database management system. The Sybase system is based on a requestor server architecture where the application functions can be handled separately from the data management functions. The DataServer and the DataToolset are the basis of Sybase. The DataServer handles data management functions for all users on the system. The DataToolset provides a set of window-based tools for building and running applications on either character terminals or bit-mapped workstations. Sybase has users in government and defense, banking and finance, and telecommunications, and sees applications for its product in computer integrated manufacturing; order entry; customer service/support; automated portfolio management; loan management; just-in-time inventory control; telemarketing; and directory assistance. Current customers include Chemical Bank, Johns Hopkins Hospital, Pacific Bell and TRW. The Sybase DataServer and DataToolset combined are priced from $15,000 to $150,000 for minicomputers and from $1,000 to $10,000 for supermicro workstations. The price for the database program is tied to that of the target processor.
