	abstract = {In this paper, we present data management issues faced during the design and development
of an open distance learning system for the University of Patras, Greece. In order to handle
data e\&$\#$129;ciently, as required in a web tele-training application, for each type of information
maintained, di\&$\#$128;erent strategies must be deployed according to their behaviour and structure.
The diversity and complexity of data, the network aspect of the application and web de{\textregistered}-
ciencies impose an architecture design incorporating a plethora of technologies and tools that
must be integrated in such a fashion that they e\&$\#$129;ciently organise these data preserving their
relationships. This presents a software engineering challenge requiring coherence of solutions
at all levels: structures, consistency, security, models, and protocols. The paper presents the
data components of an open and distance learning (ODL) system that access the information
stored in a database and the {\textregistered}le system, their underlying technology, their interaction with the
network services, and features regarding the ways they address issues faced in an open vendorindependent
distance learning environment and outlines the system{\textquoteright}s overall architecture. In
addition, this paper presents the architecture, the design and the services of a network-based
information system that supports open and distance learning activities. The open and distance
learning information system (ODLIS) o\&$\#$128;ers synchronous and asynchronous distance learning
and management of information system (MIS) services to support the educational procedure.
The ODLIS is a web-based application, which runs over the Internet using real time protocols.},

	abstract = {<p>In this paper we present a Web-based, database oriented CSCW system to support information dispersal between di{\texteuro}erent Local Government authorities (Region, Prefecture and Municipalities) and the citizens. The system is implemented around the {\textquoteleft}shared workspace{\textquoteright} notion, a group of directories and {\textregistered}les controlled by the users of the workspace. Intranet and Extranet technologies are exploited to enable asynchronous and synchronous co-operation, manipulation of information from heterogeneous sources, security and easy administration, providing in parallel advanced communication facilities. We propose an innovative approach for the development of shared workspaces over WWW, based on state-of-the-art software platforms, integrating WWW and database technologies. The whole system was developed under a project funded by the Greek General Secretariat of Research and Technology and aims in the ecient distribution and management of information between and within di{\texteuro}erent types of local authorities (Municipalities, Prefectures).</p>
