A metadata approach to multimedia database federations
Recent research in federated database systems has advanced in the direction of federations of multimedia databases. However, in each project studied, there has been little emphasis placed on the subject of meta-models. Conversely, standard database systems (relational, object-relational and object-oriented) define metadata models that lack multimedia and federation features. In this paper, a sp...
متن کاملDesign Support for Database Federations
Proc. 18 International Conference on Conceptual Modeling (ER'99, Paris, Nov.'99), LNCS, Springer-Verlag, 1999. Federated database systems provide a homogeneous interface to possibly heterogeneous local database systems. This homogeneous interface consists of a global schema which is the result of a logical integration of the schemata of the corresponding local database systems and le systems. I...
متن کاملBuilding Software Federations
Components Of The Shelf tools (COTS) are now widely distributed, of good quality, relatively cheap and cover most of the application domains. It is thus a surprise to consider that it is uncommon to reuse COTS when building large applications. At least it is recognized that building a large application based on COTS is a tough issue. This paper seeks to show why it is difficult; it is argued th...
متن کاملSIGMAFDB: Overview of the Magdeburg-Approach to Database Federations
Our research activities in the eld of federated database systems (FDBS) are closely related to the SIGMAFDB-project which is founded by the German state Sachsen-Anhalt since 1995. In this extended abstract, we present our view on federated database systems and sketch some of the main results of the work of our group. We brie y discuss di erent research aspects and implementation activities. Due...
