* Generally, it is responsibility of implementing class to decide which
* technology to use for mapping and how it should be configured.

* The write method is responsible for making sure that any internal buffers are
* flushed. If a transaction is active it will also usually be necessary to
* discard the output on a subsequent rollback. The resource to which the writer
* is sending data should normally be able to handle this itself.
