Description copied from class: nectar.data.DataAdapterService

Signal the beggining of a Transaction. The returned ConnectionHandle holds an active Connection to the DataSource, and will buffer data updates sent to the DataAdapter until commitTransaction is called.

You MUST absolutely liberate this connection with commitTransaction or rollbackTransaction, since the ConnectionHandle reserves a DataSource connection for exclusive use.
