VMark Software Inc, Westborough, Massachusetts, has released data access middleware for accessing corporate data, and calls it HyperStar 3.0. It uses object messaging technology to access Microsoft Excel, Lotus 1-2-3, Visual Basic and other Open Data Base Connectivity-compliant software to access Oracle, Sybase, Informix, uniVerse, DB2 and Cobol files. It has an application programming interface for access to Unix, Windows and Macintosh clients. Release 3.0 adds support for access to data stored on IBM’s DB2 database management system on the MVS mainframe operating system and expands HyperStar’s support for DB2 on RS/6000. It also includes an enhanced version of the Open Data Base Connectivity client which has greater compliance with Microsoft’s ODBC 2.0 specification. Release 3.0 includes the HyperStar Server for Micro Focus Cobol files, a server for full desktop read-write access to remote Cobol data through application programming interfaces. This access is via Open Data Base Connectivity-compliant tools such as Visual Basic programs and Cognos Impromptu, which can be done without writing custom Cobol programs. VMark has also released the HyperStar Server for DB2 on MVS. This is being beta tested this quarter and will be available in the first quarter of 1996. HyperStar 3.0 will be available from December 1, and costs from $2,500 in most Unix environments to $25,000 for MVS. Charges for concurrent users in Unix begin at $400, and for MVS at $1,500. Data General Corp, Westborough, Massachusetts, will be reselling the the Cobol version of HyperStar 3.0.
