What do you mean by a large quantity of data? Modern databases can
manage vast amounts of data efficiently. It is very rare for the
bottlenecks in a system to be where you expect them to be when you
start out and it is very likely that you will find that the extra work
was a waste of time. Start with a single database and make sure you
have good automated test coverage. Then in the unlikely event that
you find that you do have split the database then you can refactor the
code and the tests will help to ensure that you have not messed
anything up.
