Zusammenfassung:The paper is concerned with the design and implementation of a relational system for management of Large Data Bases (LDB) at M.I.T., Project MAC. The following six major requirements were determined for the management of LDB in a dynamically varying environment, such as an Interactive Management System: high degree of flexibility; data independence; ability to operate on different data structures; access path independent of data structure; access control below the file level; uniform retrieval time. The view is taken that information one might store in the LDB consists of sets of data elements and sets of relations among data elements. The basic set theoretic operations are used for manipulating and operating upon these sets. (Author).
