Heterogeneous organisation of data

Objetivo



The trial application focuses on heterogeneity with respect to the semantics of data in structured databases (e.g. relational, network, or hierarchical databases) and heterogeneity with respect to media used for representation (i.e. multimedia databases). Tools and methods that were developed in the Esprit projects TEMPORA and INTUITIVE will be applied and evaluated in several applications. Extensions of TEMPORA provide the basis to support semantic modelling for integration of heterogeneous databases. INTUITIVE provides the basis for integration of heterogeneous multimedia types and information retrieval tools. The objectives of the trial application are (i) to test the practical viability of the tools and methods when applied on problems of heterogeneous databases, and (ii) to identify requirements for further development of appropriate tools in order to achieve a general product.

HOD will conduct two trial applications: one which deals with heterogeneous administrative databases installed in various units of a large oil company (STATOIL) and one which deals with heterogeneous customer databases installed in various units of a large service and communication organisation (Sweden Post). The activities of the trial meet two key business objectives of the organisations: to facilitate the management and access to heterogeneous information, and to improve the agility of the organisations' use of such information.

Proper management of information provides organisations with competitive advantages, but information resource management may be particularly difficult in medium to large sized organisations, since they mostly have their information distributed across a variety of databases, managed by different organisational units. The results from the trial application may benefit every organisation that needs to manage heterogeneous information from diverse electronic sources.

The two technologies that were developed in TEMPORA and INTUITIVE are used together to form an information access facility for heterogeneous databases based on a data warehousing approach. Thus, the TEMPORA and INTUITIVE tools operate on copies of the databases and are not linked directly to the production databases. The database copies are managed by using the TEMPORA and INTUITIVE technology in such a way that heterogeneous information can be extracted in various ways from the databases and represented in a user-oriented and uniform manner.

The expected results from the proposed trials are:

- experience in using the TEMPORA and INTUITIVE technologies for accessing heterogeneous information in various application domains,
- demonstrations of the suitability and viability of these technologies in industrial applications,
- demonstration of the application independence of the approaches, and
- demonstration of the technologies for accessing heterogeneous information from diverse electronic sources.

The exploitation aspects will include analysis of potential market penetration, marketing plans and assessment of development needed in order to achieve a general product.
