Abstract
Techniques are presented for mapping a physical table to multiple virtual tables. One or more fields within a results set from a query are mapped or associated to one or more virtual tables. The virtual tables are organized as sub graphs and connected together as a set. A reference to the set is provided to a table join analysis service and a join is performed against the set to produce a single logical reference to a table. The single table reference may be treated as a single table for purposes of subsequent search and retrieval by a searcher.
