Unisys

MITEM enables organizations that run on Unisys platforms to enhance, extend and integrate such systems, making them active participants in new applications and in service-oriented architectures (SOA). MITEM accomplishes this by using its signature product, MitemView, to non-invasively integrate systems via the development of composite applications that allow systems to share critical data and automate business processes.

Unisys has a long history, dating back as far as 1873, but it was not until 1960 when their first mainframe computer system was launched: the Sperry Rand UNIVAC 1100 Series. Further models followed with the introduction of dual and multiprocessors up until 1984 when the A series was launched, a forerunner of the current ClearPath HMP NX System. In 1986 Sperry and Burroughs merged to form Unisys Corporation, and with it came the launch of the Unisys 2200 Series mainframe computer. Further enhancements were made until in 1995 ClearPath heterogeneous multi-processing was launched which allowed A series and 2200 series applications and databases to run with UnixWare and Windows NT applications and databases on a single platform.

Some of the Unisys systems included:

• 1960 – UNIVC 1100 Series
• 1962 – 1972 - UNIVAC 1107, 1106, 1108, 1100
• 1975 – UNIVAC 1100/10 , 1100/20, 1100/40, 1100/181
• 1978 – UNIVAC 1100/80, 1100/60, 1100/70, 1100/90
• 1984 – Unisys A Series
• 1985 – Sperry 2200/100
• 1986 – Unisys 2200/200, 2200/400, 2200/600, 2200/100, 2200/500, 2200/900
• 1997 – 2200/3800

Integrating Unisys-based Applications

Unisys has an extensive background in mainframe-class systems and is still a major vendor in the high performance server market. Many businesses still run UNIVAC-based systems with mission-critical applications depending on the reliability of this platform. But, as with many mainframe systems of the day, the Unisys applications were never designed to integrate with other computer systems. In fact, the only interface to the system was that of the end-user, through the terminal/workstation devices.

The applications residing on the Unisys mainframes would have been written to support specific terminal types, and the transport of information to and from those terminals and the Unisys mainframe would utilize what is referred to today as the terminal data stream. This terminal data stream is the only ubiquitous, non-invasive application interface provided by such a legacy application. MitemView utilizes this data stream as an application interface. The data streams most commonly used on Unisys mainframes are UTS and T27.

This means that applications that run on Unisys systems can now be integrated, non-invasively and in real-time, with new applications whether they are composite applications, packaged or web-based. These applications include:

• Web-to-host solutions;
• Message brokering and Message transformation;
• Composite Application Development;
• Service Oriented Architecture (SOA);
• Web Services;
• User Interface Development;
• Business Process Transformation;
• Workflow re-engineering.
