Since changes caused by database updates combine with the internal changes caused by database schema evolution, an integrated provenance management for data and metadata represents a key requirement for modern information systems. In this paper, we introduce the Archived Metadata and Provenance Manager (AM&PM) system which addresses this requirement by (i) extending the Information Schema with the capability of representing the provenance of the schema and other metadata, (ii) providing a simple time-stamp based representation of the provenance of the actual data, and (iii) supporting powerful queries on the provenance of the data and the history of the metadata.
