Welcome to the Full Disjunction Project Home Page

The full-disjunction operation is a variation of the join operator that maximally combines tuples from connected relations, while preserving all information in the relations. Useful for integrating heterogeneous data sources (e.g., web sources).

The Full Disjunctionproject is a PostgreSQL Community project that is a part of the pgFoundry.

The pgFoundry page for the project is at http://pgfoundry.org/projects/fulldisjunction, where you can find downloads, documentation, bug reports, mailing lists, and a whole lot more.
