  • Persistent archives
    Patent number: 7536425
    Abstract: A persistent archive of a collection of data objects comprises a self-describing, infrastructure-independent representation of a logical structure for the collection and a self-describing, infrastructure-independent representation of the data objects. The archive is persistent in that it may be instantiated at an indefinite point in time in the future regardless of the state of technology at that time. A knowledge-based persistent archive of a collection of data objects comprises the foregoing two elements but also a self-describing, infrastructure-independent representation of knowledge relevant to the collection.
    Type: Grant
    Filed: December 30, 2004
    Date of Patent: May 19, 2009

  • Method and apparatus for achieving uniform data distribution in a parallel database system
    Patent number: 5970495
    Abstract: The invention provides a method and apparatus for distributing data of a table substantially uniformly across a parallel database system having a plurality of interlinked database nodes. Data of the table is distributed across a group of nodes (nodegroup) in accordance with a partitioning arrangement. Resource loading, for example, the workload or storage volume of the nodes is monitored. Data is moved from one or more nodes having higher resource loading to nodes having lower resource loading to achieve a substantially uniform distribution of the resource loading across the group of nodes concerned. In the course of moving data the selection of groups of data to be moved is performed in a manner to reduce the amount of data movement.
