Detailed Description

The DataTransaction class wraps the underlying database's transaction model.

DataTransactions automatically start an isolated database transaction upon creation. The DataTransaction class can then be used with Query and DataItem objects. Each DataTransaction instance maintains its own dedicated connection to the database.
