A Kernel Design for a Secure Data Base Management System
The need for reliable protection facilities, which allow controlled sharing of data in multi—user data base management syst~ms. is steadiLy orowing. This paper first discusses concepts relevant to such protection facilities, including data security. object granularity, data independence, and software certification. Those system characteristics required for reliable security and suitable functio...

15 صفحه اولData Structures for an Integrated Data Base Management and Information Retrieval System
New applications like office information systems need interfaces to data bases which integrate classical data manipulation with management and retrieval of textual (“unformatted”) data. The relational data model is widely accepted as a high level interface to classical (“formatted”) data management. It turns out, however, to be inconvenient for handling even simple data structures as commonly u...

Individual users and applications are generally interested in only a subset of the data stored in the database. Often, they wish to see this subset structured in a way which reflects their particular needs. Since it is not generally possible to structure a database so as to...
