摘要：We present an overview of GProM, a generic provenance middleware for relational databases. The sys-tem supports diverse provenance and annotation management tasks through query instrumentation, i.e.,compiling a declarative frontend language with provenance-specific features into the query language ofa backend database system. In addition to introducing GProM, we also discuss research contributionsrelated to GProM including the first provenance model and capture mechanism for transaction prove-nance, a unified framework for answering why- and why-not provenance questions, and provenance-aware query optimization. Furthermore, by means of the example of post-mortem debugging of transac-tions, we demonstrate how novel applications of provenance are made possible by GProM.
