  • Jones, Vicki Ellen (1997)
    This thesis shows how to obtain efficient, fine-grained (object-level) control over user access to ODB data. We present a target access control model for ODB applications and delineate the trust assumptions required for ...

  • Yu, Ting (2003)
    Without proper protection, an access control policy itself might reveal sensitive information unintentionally. To remedy this problem, we propose a unified scheme for resource protection in ATN. This scheme treats policies ...

  • Chodpathumwan, Yodsawalai (2018-12-02)
    People structure and represent their data in many different ways. One factor to consider in choosing between different representations is how the structure will affect the effectiveness of algorithms that run over the data. ...

  • Sinha, Rishi Rakesh (2007)
    To address these three problems, we introduced multi-resolution bitmap indexes, which group data into bins at multiple granularities. We achieved a query performance which is 10 times faster than traditional bitmap indexes ...

  • Smith, Kenneth Paul (1992)
    Traditional databases are viewed as passive repositories of data. We store, retrieve, and alter data in a database, but do not expect a database to respond to actions performed to it. This passive paradigm is now rapidly ...
