    Summary form only given, as follows. Research in the area of subquery unnesting algorithms has mostly focused on the problem of making queries more efficient at run-time by transforming subqueries into joins. Unnesting rules describe a transformation of a nested query tree or a nested SQL query into an equivalent tree or SQL query that is no longer nested. However, it is not possible to express al...

  • Content is king (If you can find it): a new model for knowledge storage and retrieval

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (820 KB)

    The technology for acquiring and storing vast amounts of complex data is accelerating at a much faster rate than the technology for retrieving and analyzing that data. While progress has been made with OODB, OLAP, and knowledge discovery (KD) systems, users of these systems are still required to know and supply missing semantic information. When dealing with complex real-world representations, thi... View full abstract»

  • SEOF: an adaptable object prefetch policy for object-oriented database systems

    Publication Year: 1997, Page(s):4 - 13

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (828 KB)

    The performance of object access can be drastically improved by an efficient object prefetch policy. In this paper, we present a new prefetch policy, called Selective Eager Object Fetch (SEOF), which prefetches objects only from selected candidate pages without using any high-level object semantics. Our policy considers both the correlations and the frequencies of fetching objects. Unlike existing... View full abstract»

  • Media asset management: managing complex data as a re-engineering exercise

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (868 KB)

    Building a media asset management application involves the storing, searching, and retrieving of complex data. How this data is managed can be viewed from two perspectives-in terms of the internal representation required to allow for high-speed searching and transferring of these items between systems, but also from the end-user perspective. This paper focuses on the perspective that media asset m... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (88 KB)

    ROCK & ROLL is a deductive object oriented database system that supports two languages, one imperative and the other deductive, both derived from the same object oriented data model. As the languages share a common type system, they can be integrated without manifesting impedance mismatches, and thus programmers can conveniently exploit both deductive and imperative features in a single applic...

    We propose a data model for representing moving objects in database systems. It is called the Moving Objects Spatio-Temporal (MOST) data model. We also propose Future Temporal Logic (FTL) as the query language for the MOST model, and devise an algorithm for processing FTL queries in MOST View full abstract»

  • WOL: a language for database transformations and constraints

    Cited by:  Papers (3)  |  Patents (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1000 KB)

    The need to transform data between heterogeneous databases arises from a number of critical tasks in data management. These tasks are complicated by schema evolution in the underlying databases and by the presence of non-standard database constraints. We describe a declarative language called WOL (Well-founded Object Logic) for specifying such transformations, and its implementation in a system ca... View full abstract»

  • Delegation: efficiently rewriting history

    Publication Year: 1997, Page(s):266 - 275
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (956 KB)

    Transaction delegation, as introduced in ACTA, allows a transaction to transfer responsibility for the operations that it has performed on an object to another transaction. Delegation can be used to broaden the visibility of the delegatee, and to tailor the recovery properties of a transaction model. Delegation has been shown to be useful in synthesizing advanced transaction models. With an effici... View full abstract»
