Abstract
In database querying, provenance information can help users
understand where data comes from and how it is derived. Storing the
provenance data is critical in the sense that, the storage cost should be
as small as possible and of fine granularity, and it should support the user
query on provenance tracking efficiently as well. In this demo, we have
implemented a relational database system prototype which can support
SQL-like query while supporting provenance data recording during query
execution. In particular, we propose a tree structure to store provenance
information and further propose various reduction strategies to optimize
its storage cost; we support the functionality of provenance data tracking
at tuple level for user queries in a visualized way.
