In this demonstration we present the Perm provenance management system (PMS). Perm is capable of computing, storing and querying provenance information for the relational data model. Provenance is computed by using query rewriting techniques to annotate tuples with provenance information. Thus, provenance data and provenance computations are represented as relational data and queries and hence can be queried, stored and optimized using standard relational database techniques. This demo will show the complete Perm system and let attendants examine in detail the process of query rewriting and provenance retrieval on what is today the most complete data provenance system available.
