Abstract
A system and method for accepting and responding to queries based on information stored on multiple heterogenous information sources. A uniform query interface to large collections of structured information sources is provided to a user to pose queries using a uniform schema of the available information. A query plan for answering the query is formulated from descriptions of the contents and capabilities of the available information sources. Based on these descriptions logical solutions which are subsets of the complete solution to the query are derived. An order for executing these solutions is determined based on the input requirements and other capabilities of the relevant information sources.
