In this paper we describe a preliminary design and implementation of a multilevel secure deductive database management system (MLSIDEDBMS). In particular, logic as a dara model for multilevel databases, reasoning across security levels, architectural issues for an MLSIDEDBMS, and a prototype implementation are discussed.

Textual fields are commonly used in databases and applications to capture details that are difficult to formalize—comments, notes, and product descriptions. With the rise of the web, users expect that databases be capable of searching these fields quickly and accurately in their native language. Fortunately, most modern database systems provide some form of full-text indexing of free text field...

This paper describes a new architecture for a system to handle temporal data, called Temporal Data Management System, TDMS. TDMS represents an approach to the modelling of temporal semantics which is pragmatic because it takes into account practical issues such as the time /space trade-offs. We consider the technical aspects of the system i.e. how time domain data is managed in TDMS. The design...

1. Introduction Database management systems (DBMS) provide higher level user support than conventional operating systems. The DBMS designer must work in the context of the OS he/she is faced with. Different operating systems are designed for different use. In this paper we examine several popular operating system services and indicate whether they are appropriate for support of database managem...
