Abstract
A virtual database system including multiple independent database servers is disclosed. The virtual database system uses a unified interface to query multiple independent databases, and the multiple independent database servers include appliances, general servers, etc. The system preferably includes a packet-based network, and a number of physically separated, independent database servers coupled to the network, where each of the database servers has a unique address and an independent database interface. Preferably, each database server includes an database created at least in part by the passive capture of data on the network, and each of which supports database queries including at least one of metadata and text via its respective interface. Queries are distributed concurrently to a number of appliances as virtual user queries.
