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.

Architecture to enable search gateways as part of federated search

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.

Architecture and implementation of a dynamic RMI server configuration hierarchy to support federated search and update across heterogeneous datastores

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.

Delayed delivery of query results or other data from a federated server to a federated client until such information is needed

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.
