Can any one tell about distributed databases? What's the real use?

In a Distributed Database, the entire database is not stored on one computer. The database itself (tables) may be spread over more than one computer or the database may also be replicated among more than one computer.

A distributed database can be used to improve the fault tolerance of a network (if the database is replicated). A group of computers having the same database can be configured for load sharing. There are many more uses.

Problems with data consistency have to be addressed when distributed databases are being designed.

For more info - http://en.wikipedia.org/wiki/Distributed_database shoule be a good starting place.
