Federated Searches Of Heterogeneous Datastores Using A Federated Datastore Object

US Patent:

6578046, Jun 10, 2003

Filed:

Jun 5, 2001

Appl. No.:

09/873220

Inventors:

Daniel T. Chang - San Jose CA
Siyi Terry Donn - Saratoga CA
Douglas Michael Hembry - Los Gatos CA
Tae Jae Lee - Cupertino CA
Basuki N. Soetarman - Los Gatos CA
Robert N. Summers - San Jose CA

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 1730

US Classification:

707103, 707100, 707 10, 707 4

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.

Class Hierarchy For Object Aggregation Representation Of Relational Database Rows With Cells Having Nontraditional Datatypes

US Patent:

5960438, Sep 28, 1999

Filed:

May 6, 1997

Appl. No.:

8/852062

Inventors:

Daniel T. Chang - San Jose CA
Douglas M. Hembry - Los Gatos CA
Basuki N. Soetarman - Los Gatos CA
Robert N. Summers - San Jose CA

Assignee:

International Business Machines Corp. - Armonk NY

International Classification:

G06F 1730

US Classification:

707103

Abstract:

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.

System And Method For Providing A Graphical User Interface For Mapping And Accessing Objects In Data Stores

US Patent:

5627979, May 6, 1997

Filed:

Jul 18, 1994

Appl. No.:

8/276389

Inventors:

Daniel T. Chang - San Jose CA
Christina Lau - Ontario, CA

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 300

US Classification:

395335

Abstract:

A graphical user interface for mapping and accessing objects in data stores is disclosed. A user may define a mapping between object schema and data store schema by use of a high level language, Schema Mapping Definition Language (SMDL), which is data store independent, object oriented language independent, and extensible. The user may either write SMDL directly or generate SMDL through the use of a graphical user interface Smart Schema whose graphical semantics support the SMDL semantics. A Schema Mapping Internal Representation (SMIR) containing representations of the object schema, the data store schema, and the mapping of the object schema and the data store schema is generated by an SMDL Parser from the SMDL. The SMIR is represented such that it may be accessible by both development interfaces and run-time environments. It supports the accessing of the mapping information given either the object schema or data store schema such that the data store schema may be accessed from the object schema, and the object schema may be accessed from the data store schema.

Method And Apparatus For Creating An Index In A Database System

US Patent:

6240407, May 29, 2001

Filed:

Dec 17, 1998

Appl. No.:

9/215036

Inventors:

Daniel T. Chang - San Jose CA
Josephine Miu-Kung Cheng - San Jose CA
Jian Xu - San Jose CA

Assignee:

International Business Machines Corp. - Armonk NY

International Classification:

G06F 1730

US Classification:

707 2

Abstract:

A method, apparatus and article of manufacture for computer-implemented creation of an index in a database system is defined, wherein a structured document, interactively entered by an operator or already stored in the database system, is parsed into at least one corresponding element, then abstracted using a predefined abstraction procedure to obtain a set of abstracted values, the set of abstracted values being stored in the index for efficient execution of structured queries.
