Week 2 Report

Setting up RPQ engine develped by Michael Wang and run some example on it.

This engine provides a platform of RPQ against relational databases. RPQ will be translated to SQL queries and executed on postgresql database. Also this engine is built for querying provenance, with couple of following up modifications, we can use to query the existing provenance database we have.

Solved issues
– Postgresql user name authority
– Code version inconsistency
– Transitive closure query function
