ReX: Representative extrapolating relational databases

作者：

Highlights：

• An automated database extrapolation system that generates a representative extrapolated database of an original database, given a rational scaling rate.

• An automated sampling method, called RVFDS, that aims to generate a representative sample of the original database. This method is used in addition to the extrapolation method to handle rational scaling rates.

• A comprehensive experimental comparison, using both real and synthetic databases, between a state-of-the-art scaling technique, namely UpSizeR, and our proposed representative scaling system, ReX.
