Prototypes and Products 5. Optimisation of OPJ and Java VM performance Versioning of object instances and classes Opportunities to demonstrate these technologies in other applications will be developed. Planned demonstrations are in defence and value-added meteorological services and and geospatial information systems support. A rapidly growing demand for networked information stresses the need for effectively managing large amounts of complex data. This information explosion is characterised by heterogeneity of data and increased requirements for scalability, efficient data stores and portability across a range of platforms from high performance servers to PCs.
Object technologies provide a viable means to handle large complex data.
The Theme will provide the technological support for ACSys programs and projects to make use of emergent object technologies. While much commercial attention is focused on relational and object-relational approaches to persistent data management, it seems to be increasingly clear that the mismatch between the relational paradigm and object orientation will be insurmountable for some classes of problem. Furthermore, commercial object oriented databases are unable to fulfill these requirements in a scalable or portable manner. Our objective is the creation of data management solutions that bridge this gap and so lead to more general solutions that those offered by current technologies. Design and construction of image and geospatial data repository with special experience in handling large object data systems.
