چکیده

Mobile information systems integrating information from different sources and feed mobile clients represent a big challenge for todays DBMS technology. Due to the limited capabilities of the clients (available memory, usable bandwidth, temporary disconnections etc.) traditional replication approaches known from distributed databases fail. In this paper we present an approach for data replication that considers the mobility of clients: The data sets which have to be replicated to mobile clients depend often on dynamic parameters like location of the client or time. Therefore, we introduce a generic model for specifying fragments of the global database with respect to such parameters.

Database Schema Detection and Mapping on Mobile Applications: An Ontology-based Approach

In the growing field of Mobile Information Systems, there is a need for systems architectures that facilitate access to heterogeneous information components to guarantee the availability of information stored in databases. A mobile system should access different databases depending on user characteristics (e.g. GPS localization, user profile, user preferences). The semantic understanding of inf...

Context-driven RDF data replication on mobile devices

With the continuously growing amount of structured data available on the Semantic Web there is an increasing desire to replicate such data to mobile devices. This enables services and applications to operate independently of the network connection quality. Traditional replication strategies cannot be properly applied to mobile systems because they do not adopt to changing user information needs...

Building Secure Data Warehouse Schemas from Federated Information Systems

Introduction There are many heterogeneities among preexisting informations sources, such as DataBases (DBs), particularly semantic heterogeneities (see our chapter “Semantic Heterogeneity” in [1]). Any secure Federated Information Systems (FIS) must solve them, and deal with a): how schema levels are related to security, and b): operations on schemas to convert from level to level. We present t...

Schema Evolution in Federated Information Systems

Mediators – used in federated information systems – provide a homogeneous read-only access to a set of autonomous information sources. To achieve semantic integration of the heterogeneous data, correspondences between the autonomous schemas are specified manually by experts. Considering the continuous evolution of those typically long-living information systems, schema evolution is an important...
