I&W (Indications and Warning) Data Base Management Systems Analysis

摘要

The objective of this effort was to identify the data base management system that seems to best support the Indications and Warning analyst using a given hardware and operating system configuration. Hardware and operating system constraints were to utilize a Digital Equipment Corporation PDP 11/70 computer running the IAS operating system. This configuration is the DOD standard intelligence support processor. A precise description of an Indications and Warning data base was developed from scenarios constructed by observing analysis at DIA, SAC, MAC, and ADCOM. The description ws then used to construct a simulated data base. Scripts were developed from each scenario to generate activity against the data base. Software was developed to allow execution of repeatable tests, each with psuedo-randomly variable conditions. Important developments of this effort included; the precise characterization of an I and W Data Base, the DHIL language, used to describe the scenarios and the data base, the set of analyst scenarios, which accurately describe the functions and activities of intelligence analysts, and a hardware/software configuration usable for evaluating the performance of data base management hardware and software in the future.
