  • Patent number: 6578046
    Abstract: A computer method and system capable of searching multiple heterogeneous datastores with heterogeneous data types by employing an object oriented data model to define a federated datastore object. The federated query object translates a generic query into the appropriate queries for each datastore, the federated datastore object acts as a virtual datastore for multiple heterogeneous datastores with the ability to map concepts between datastores, and the federated collection object represents results from a federated query in a hierarchy that maintains sub-grouping information from each datastore to allow accessing of results by datastore or as a single collection of results. The federated objects thus provide user applications with enhanced accessibility of different hierarchies of information, as well as more robust search capabilities.

  • Patent number: 6397203
    Abstract: A method, apparatus, and article of manufacture for defining object classes to match corresponding specialized data types stored in a relational database. An object-oriented application program may create an instance of a class for the purpose of representing data in a relational table that comprise a specialized data type. The attributes and behavior of the specialized data type in the database are preserved, where appropriate, in the corresponding class, and are available to the application program.

  • Patent number: 6078925
    Abstract: This invention is directed to relational extenders for a computer-based relational database. Each relational extender includes at least one column, in a first, business, table containing a user defined application database, dedicated to object handles for defining the complex data type of an object; a second, attribute, table containing at least one column defining a unique characteristic associated with the one object and one column dedicated to containing the object handle; and a third, metadata, table containing at least one column defining a common characteristic associated with all objects defined within the business table and one column dedicated to containing the object handle and at least one column dedicated to containing a reference to object data associated with the object.
