h2. Apache ShardingSphere
Apache ShardingSphere is positioned as a Database Plus, and aims at building a
standard layer and ecosystem above heterogeneous databases. It focuses on how
to reuse existing databases and their respective upper layer, rather than
creating a new database. The goal is to minimize or eliminate the challenges
caused by underlying databases fragmentation.
