Quik. Connect user profile SEC EDGAR Project TRW, on contract to the US Securities Exchange Commission, used Quik. Connect as the message-oriented middleware for a large multi-host, mixed-vendor system. QC is the “glue” that interconnects HP-UX, Solaris, Stratus VOS, Stratus FTX, OS/2, and NT machines for the Electronic Data Gathering and Retrieval System (EDGAR) to report all corporate filings to the US government.

Quik. Connect benefits Combines • Fault tolerant processing power of the Stratus server • User interface features of desktop workstation • Speed and reliability of a LAN • Open Systems architecture Provides • High performance access to distributed applications • Distributed client application processing • No required changes to existing server applications • Access to “off the shelf" tools and applications • More flexible system expansion © 1995 SCI Group, Inc.

QC Distributed Client Benefits § Takes advantage of PC tools like Windows, graphics, imaging § Allows application processing without using critical server computing resources § Applications include image capture, data entry, editing, local file access, terminal management § Improves transaction throughput: • Data transferred at LAN speeds • Processing matched to architecture of computer • Breaks application at most efficient point § Retains fault tolerant server essential to application § Provides flexible system expansion © 1995 SCI Group, Inc.

Quik. Connect offers Stratus users: VOS to Unix (HP-UX, Solaris, FTX) application migration § Servers or requesters can be ported separately § VOS & Unix requesters can access same VOS servers § VOS & Unix requesters can access same Unix servers § VOS requesters can access both VOS & Unix servers § Unix requesters can access both VOS & Unix servers VOS to Unix ports § VOS applications can retain VOS-like TPF architecture when ported to HP-UX, Solaris or FTX § VOS users can continue to use familiar TPF facilities © 1995 SCI Group, Inc.
