DoD (Department of Defense) Gateway Information System (DGIS): Common Command Language Mapping

摘要

The DoD Gateway Information System (DGIS) Common Command Language (CCL) project was initiated to provide a single standard command language for searching any online database system. This report relates the requirements analysis for the initial CCL prototypes in C language. Requirements were determined of six online database systems: DROLS, DIALOG, NASA/RECON, BRS, ORBIT, and MATRIS, using the National Information Standards Organization (NISO) draft standard for Common Command Language as a basis. Four C prototypes were completed: DROLS, DIALOG, BRS, and NASA/RECON. At that time the decision was made to incorporate Artificial Intelligence Capabilities into CCL, and the programming of the CCL translators was converted to PROLOG. (Author)
