Integrated Information Support System (IISS). Volume 4. IISS System. Part 4. System Integration Test.

摘要

This document is a comprehensive package to demonstrate an application executing in the IISS environment. This demonstration uses all four subsystems of the IISS, namely, Common Data Model (CDM), User Interface and Virtual Terminal Interface (UI/VTI), Network Transaction Manager (NTM) and the Communication (Comm) Subsystem. The application is written using the UI/VTI application definition language, and COBOL and accesses the CDM data dictionary to retrieve information about the databases and where the data resides and processes distributed queries using the NTM and COMM. At any one stage during the demonstration, an application may be accessing up to three databases on three different DBMS and processing data retrieved across two computers - IBM and VAX.
