capable of powerful and efficient knowledge based processing, called Knowledge Based Management System (KBMS) has become popular as a result of merger of these two technologies. KBMS is a system providing highly effective management of large shared knowledge bases for knowledge directed systems (Brodie, 1986). A major reason for the integration of these two technologies is the realization that ...

This paper describes the external forces that motivate financial institutions to collect, aggregate, analyze, and mine data so that it can be transformed into information, one of a financial institution’s most valuable assets. In this paper we refer to this strategic information asset as “information currency.” In general, we describe the state of banking and the rapid global changes that affec...

In order to improve the robustness of systems that perform similarity searching, it may be necessary to augment a collection of images in a Multimedia DataBase Management System (MMDBMS) with an additional set of edited images. Previous research has demonstrated that space can be saved in such a system by storing the edited images as sequences of editing operations instead of as large binary ob...

A Database Management System (DBMS) consists of metadata and data. The metadata influences the way the data is presented to the user and this presents various forensic complications. The data model can be viewed as the highest level of metadata which governs the way other metadata and data in the DBMS are presented to the user. The data model can be modified to hide or tamper with forensic evid...

We argue that a fully object-oriented database management system is a very suitable basis of every modern CASE environment. We describe how the features provided by an OODBMS are exploited to build a CASE tool or environment. We discuss especially problems concerning inter-document consistency constraints and multi-user support. We nally sketch the features which are still missing in OODBMSs.

A traditional database systems is organized around a single data model that determines how data can be organized, stored and manipulated. But the vision of this paper is to develop new principles and techniques to manage multiple data models against a single, integrated backend. For example, semi-structured, graph and relational models are examples of data models that may be supported by a new ...

Industrial applications frequently involve manipulation and management of pictorial information. In spite of the fact that digitized images and pictorial information are becoming more significant as parts of user databases, conventional database techniques have focused primarily on numerical and textual information. The Image Database Management System (IDBM) extends these techniques to encompa...

Our goal in this paper is to answer the following question: what mechanisms are required in a general-purpose multiuser database management system (DBMS) to facilitate the integrity objectives of information systems? We are particularly interested in relational DBMS's. Although existing commercial products fall far short of providing the requisite mechanisms, in principle they can be easily ext...

water resource constraints on the one side, the industrial and urban infrastructures which cannot cope with the growing demand, and the need for adequate planning on the other hand, emphasizes the importance of using a comprehensive and systematic approach in the field of water resources management and infrastructure development more obvious and significant day by day. also, exposure to large a...
