I mean just in case: :-) http://en.wikipedia.org/wiki/Shard_%28database_architecture%29
Shard database architecture Horizontal partitioning is a database design principle whereby rows of a database table are held separately, rather than splitting by columns (as for normalization). Each partition forms part of a shard, which may in turn be located on a separate database server or physical location. ... This is also why sharding is related to a shared nothing architecture - once sharded, each shard can live in a totally separate logical schema instance / physical database server / data center / continent. There is no ongoing need to retain shared access (from between shards) to the other unpartitioned tables in other shards.
