The currently operational relational-like structure, as well as a primitive database management system is described. The proposed file structure integrates a B-tree variant, inverted files, and other structures to provide the underlying facility. The database management system supports multi-user, multi-database retrieval through relational views of both data and documents, as well as the interface to non-procedural languages. Emphasis regarding design decisions and tradeoffs were related to: 1) the Unix* operating system; 2) the access methods supported; 3) future development, such as document processing (information storage and retrieval), concurrency control and recovery.
