Managing network resources for efficient, reliable information systems

Recent advances in public network technology and emerging database interface standards enable the implementation of a new type of distributed database systems and create demand for improved query distribution and query optimization algorithms. A research topic that immediately arises is cost minimization for ISDN usage. Even if policies for charging telephone communications may vary, it is a fair assumption that cost will be proportional to the duration of an ISDN connection, and thus, to the volume of data exchanged. Previous research on distributed database systems has produced results that can be utilized for this purpose. Nevertheless, Intelligent Network and ISDN usage requires current knowledge to be adapted and extended. The current state of telecommunication technology provides a potential for developing efficient distributed heterogeneous database systems, utilizing public data networks such as ISDN. Emerging technology and standards, such as ODBC, make the development of such systems cost effective and their operation flexible.<
