This report describes a program that was designed by the Tactical Electronic Warfare Division at the Naval Research Laboratory as an automated retrieval system for documents in the Effectiveness of Navy Electronic Warfare Systems (ENEWS) library. It contains acronyms, ship classes, and ship designations as related to the electronic warfare community. Acquisition of information from an automated retrieval system involves an interaction between the user and the computer. As with any man-machine interaction, the more demanding and more sophisticated the user's request, the greater the system effort will have to be achieve the desired goal. A complex process is undertaken when a retrieval system attempts to find material relevant to a user need. Three stages can be distinguished in the interaction of a user with the retrieval system. The process begins with presearch activities. For the user this involves determining what is to be asked of the retrieval system and then mapping the request into the system's formal query language. The programs are written in Fortran programming language and use the data manipulation language (DML) of the DEC-VAX database management system. The DML is a special set of system software that organizes, stores, retrieves, and maintains records in a file or files. It was designed as multiuser environment, which means that many users in the Tactical Electronic Warfare Division have concurrent access to the data.
