    The objective of the CARDS project (Alvey Project IKBS 140) has been to focus a wide range of expertise on to the construction of a viable very large knowledge-based system. GEC were the principal investigators and were responsible for the overall management of the project. GEC also designed and implemented the transputer pipeline, modified the operating system of the SUN workstation into a specia... View full abstract»

  • An OODB with entity-based persistence

    An object-oriented database (P/FDM) has been built as a natural extension of Shipman's functional data model (FDM) which is itself founded on entity-relationship concepts. The authors are using this (P.H.D. Gray et al., 1990), to store 50 Mb of protein structure data, including the coordinates of every atom in over 80 proteins. The database is mainly used to search for fragments of protein backbon... View full abstract»

    Ever more extensive computer systems are required by complex, multi-centre organisations. The distributed object oriented systems model matches well to these requirements, combining the attractive properties of persistent object systems with the contents addressability of the conventional relational model. The author focuses on the application of the object oriented model in large-scale concurrent... View full abstract»

  • Active memory for structure manipulation

    Publication Year: 1990, Page(s):2/1 - 2/3

    One of the perennial problems of parallel computer architectures is how to avoid unnecessary movement of information from one processor to another. The issue of unnecessary data movement is also familiar to the database community, where it manifests itself as the I/O bottleneck for a uniprocessor. Much of the problem in both cases is due to the fact that the point where data is stored is different... View full abstract»

  • Large knowledge based applications in molecular biology and genetics

    Publication Year: 1990, Page(s):6/1 - 6/5
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (264 KB)

    The informatics requirements of the molecular biology and genetics research community are becoming increasingly sophisticated and there is a developing emphasis on the integration of data from different areas of biology in order to increase the functionality and the semantic richness of the queries that can be formulated. The authors are using knowledge based methods as part of their research beca... View full abstract»

  • Temporal knowledge bases

    Traditionally a database represents a `snap-shot' of the world. When events occur and values change, the database is `updated' to reflect these changes and the previous version is overwritten. However, this practice has a number of drawbacks which are listed. The advent of high density, low cost optical disc stores has made it possible, in certain applications, to adopt the idea that no data shoul... View full abstract»
