Conceptual modeling for database design needs simple and easy to use techniques for gathering and presenting information. Furthermore these approaches must be a means for communication between different kinds of stakeholders. In this paper a combination of such techniques are presented. It will be proposed how a glossary based representation, a graphical representation as well as a verbalization of concepts can be used together for communication with the end user.
While Linked Open data (LOD) has gained much attention in the recent years, requirements and the challenges concerning its usage from a database perspective are lacking. We argue that such a perspective is crucial for...

We present a data Quality Manager (DQM) prototype providing information regarding the elements of derived non-atomic data values. Users are able to make effective decisions by trusting data according to the description of the conflict resolution function that was utilized for fusing data along with the quality properties of data ancestor. The assessment and ranking of non-atomic data is possible by the specification of quality properties and priorities from users at any level of experience.
Extracting knowledge out of qualitative data is an ever-growing issue in our networking world. Opposite to the widespread trend consisting of extending general classification methods to zero/one-valued qualitative var...

With the fast development in mobile and communication technology, the need for moving object databases increases. Moving object databases constitute a major ingredient in many applications that are location sensitive. Traffic control, fleet management, m-commerce, and E-911 are among those emerging location based services (LBSs). Along with the vast increase of location information, and the need to efficiently manage and mine those information, spatio-temporal data warehouses arise into the picture requiring new algorithms, new measures, and efficient querying techniques to efficiently utilize the historical information obtained from moving objects. In this paper we present a spatio-temporal data warehouse (STDW) that enables querying location information. Experimental results on our query performance are presented.

Fast response to users' query and update requests continues to be one of the key requirements for OLAP systems. We outline the generalization of a space-efficient data structure, which makes it particularly suited for cubes with hierarchically structured dimensions. For a large class of range-sum queries - roll-up and drill-down along dimension hierarchies - the structure requires only a constant number of cell accesses per query on average, while offering an expected poly-logarithmic update performance.
One of the major challenges in development of indexing techniques for semi-structured data is related to how to index the data structural properties. The main issue is how to efficiently handle branching path expressi...
