摘要： A program product is described in which a class library is provided to permit object oriented applications flexibly to access and to manipulate, in accordance with the object model, nontraditional data values of a relational table. Nontraditional datatypes of a relational table include multimedia and large object datatypes. The data is manipulable by virtue of extended data objects that each represent particular cells of a relational table, and that inherit type-specific behaviors from the class library.

摘要： A program product is described in which a particularly advantageous hierarchical class library is provided to permit object oriented applications to instantiate objects to access and to manipulate, in accordance with the object model, nontraditional data values of a relational table. Nontraditional datatypes of a relational table include multimedia and large object datatypes. The data is manipulable by virtue of extended data objects that each represent a cell of a relational row, and that each inherit type-specific behaviors from the class library. The class library is advantageously structured into a hierarchy that ensures the availability of certain member functions for extended data objects.

摘要： 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 query object, a federated collection object and 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.

摘要： An extender for a computer-implemented relational database system is disclosed for storing, querying, and retrieving structured documents. The extender provides a new abstract data type and includes a plurality of user defined functions for storing, querying, and retrieving structured documents internally, as character-based large objects (CLOB), or externally, in flat files or URLs, for example. A method and apparatus using an extender having a “conditional select” functionality is further disclosed for querying structured documents. The “conditional select” functionality is based on user defined functions residing within the extender being applied to a projection in a structured query in the database system. A method and apparatus using an extender having a set of user defined functions is further disclosed for creating one or more indexes for structured documents stored in the relational database system. The method uses the set of functions to create the indexes and uses already created B+ tree index structures implemented in the database system to support the indexes. A method and apparatus using an extender is further disclosed for creating and supporting structure indexes. The method includes a tag counting system for indexing structured documents and for implementing the structure indexes within the relational database.
