G06F 1730

US Classification:

707103, 707100, 707101

Abstract:

A design and implementation of a client/server framework for federated multi-search and update across heterogeneous datastores. In particular, a technique for manipulating data in one or more heterogeneous datastores at a computer is provided. An object-oriented model is provided for integrating one or more heterogeneous datastores with a federated datastore. One or more heterogeneous datastores and a federated datastore are generated based on the object-oriented model. The generated datastores are organized into a federated composition.

US Classification:

707 3, 707 1, 707 4, 707 5, 707 10, 707100

Abstract:

A technique for delayed delivery of query results or other data from a federated server to a federated client until such information is needed. One or more commands are executed at a client computer to retrieve data from one or more datastores connected to a server computer. At the client computer, a search request is transmitted to the server computer. Then, a client collection is generated for use in retrieving physical data from the server computer. When data is requested using the client collection, physical data is retrieved from the server computer.

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.

Abstract:

A method and system for transforming XML documents to and from data objects in an object oriented framework includes: importing the XML document; parsing the XML document; building a DOM tree from the parsed XML document; constructing at least one DDO or at least one XDO based on the DOM tree; and storing the DDO or XDO in a datastore. The present invention provides a transformation bridge connecting the XML world and the object world, allowing conversions from XML documents to data objects and vice versa to be performed seamlessly. It enhances the existing framework with a feature to process XML documents utilizing the existing framework facilities. Application developers can thus exploit the key advantages of XML representation as well as object orientation.

US Classification:

707 3, 707 1, 707 10, 707103 R

Abstract:

A method, apparatus, and article of manufacture for managing results of federated searches across heterogeneous datastores with a federated result set cursor object. One or more commands are executed in a computer to perform a datastore operation at a computer. Data is located in one or more datastores. A cursor is set to the located data in each datastore. A set of cursors to the located data is returned.

Abstract:

An architecture to enable search gateways as part of a federated search supports searching for data in one or more heterogeneous data sources. The one or more heterogeneous data sources are within a computer system. Initially, a request for data is received at a federated data source. From the federated data source, data is retrieved from one or more of one or more terminal data repositories or one or more search gateway data sources.

Abstract:

The present invention provides cache flushing of selected data while leaving remaining cached data intact. Data can be flushed from caches distributed across various components of a network-based computer system. These caches can contain various types of data. In one embodiment, the caches exist in an Access System and contain user identity profile information. In another embodiment, the caches exist in an Access Management System and contain authentication, authorization, or auditing rules. A system in accordance with the invention detects a change to data residing on a server and transmits a synchronization record to a component of the system. The synchronization record identifies the changed data. The system flushes the changed data identified by the synchronization record from caches of the component.

Abstract:

An architecture and implementation of a dynamic RMI server configuration hierarchy to support federated search and update across heterogeneous datastores. The RMI server configuration hierarchy supports searching for data in one or more heterogeneous data sources within a computer system. A request for data is received at a federated data source. Then, a server is selected to process the request based on a load of the server and based on whether the server can satisfy the request for data.
