Development of a Fault Isolation System Database Manager

The Fault Isolation System Database Manager FISDM is an interactive database interface developed to enhance data and configuration management of causal models. A causal model of a Unit Under Test describes the interrelationship of the electronic components composing the UUT. The interface, written in C, was integrated with the Empress data management software package to access data manipulation routines. Standard data manipulation features are incorporated to enhance the creation and management of the knowledge database. Output features allow delivery of the data in multiple formats. The format required for the Fault Isolation System FIS knowledge database is produced directly as an output option. Additionally, a comma delimited format compatible with other database and spreadsheet software provides portability and flexibility for configuration management. Data management is achieved through maintenance of a standard format which can be translated to working version in other formats. FISDM permits central management of expert systems that require occasional modifications from multiple sources. This is a situation which often occurs over the fielded lifetime of military electronic systems.
