Session B: Information Systems and Data Warehouse
Martin Malík, Tomá Kamrád: Information systems Conception of University of Ostrava

Preface

Information systems (IS) complex at the University of Ostrava, which was a starting point for the system development, had been considerably fragmented and ill sorted. Individual systems had been operated in heterogeneous environment, IS hadn‘t had a possibility of intelligent communication.

All requirements for reciprocal data transfer had had to be solved in a complicated way of exports, manual data corrections and consequential imports. As a result there had been a kind of an off-line communication, which had been very ineffective. There hadn‘t been any effort to solve an integrated user autentification against the systems; it had been necessary to administer different set of users‘ accounts and passwords in every system with their rights.

Along with rising demands on speed and effectiveness of information processing the UO was obliged to reform gradually its internal IS so that these systems could communicate without major problems, whereby the necessity of registering one change (e.g. with a person) separately to every system could be removed. It was apparent that this step would require preferably utmost unification of individual systems and mainly as a necessary condition - reinforcement of the HW background.

All the University buildings, the current number of which is about twenty, have been interconnected with optical cables, some with microwave connections. A sufficient bandwidth enabled a radical change of the backbone network technology to GigabitEthernet with a central router, which routes twelve IP networks of class C. Structured cabling (app. one thousand ports RJ 45) has been built in all the buildings; according to demands on the bandwidth switched or shared Fast Ethernet (transfer rate 100 Mb/sec.) is employed.

We can state that there has been built a modern and concerning capacity sufficient information infrastructure for operating all the information systems that are currently installed or prospectively planned.

The IS being nowadays operated in the frame of UO see pic.#1. There is an effort to use Oracle, possibly other SQL databases as a main database environment.
