  • Automated logistical relational database support system for engineering drawings and artwork
    Patent number: 5493679
    Abstract: A process for establishing a relationship between the Logistics Support Analysis Record (LSAR) database and a released engineering drawing database. The process includes establishing several database pointer tables for relating the drawings to appropriate end items, task and subtasks. As a result of the process, Logistics Support Analysis functions can be performed in less time, for less cost and with fewer errors. The query aspects of the LSAR database can be used to relate specific hardware to its maintenance procedures, special tool requirements and special handling equipment. Source engineering documents are related to publications art, and engineering drawings are related to task/subtask. The process facilitates automated change notification procedures.
