摘要：

FDB is an in-memory query engine for factorised databases, which are relational databases that use compact factorised representations at the physical layer to reduce data redundancy and boost query performance. We demonstrate FDB using real data sets from IMDB, DBLP, and the NELL repository of facts learned from Web pages. The users can inspect factorisations as well as plans used by FDB to compute factorised results of select-project join queries on factorised databases.
