It uses an implicit transaction. MSEgui version of tsqltransaction has the 
flag tao_fake in options property which enables implicit transactions for 
database connections which support them, for Firebird it is not supported. 
MSEgui version of tsqldataset has the flag dso_offline which disconnects from 
transaction after loading the data. It is possible to reconnect in order to 
write the update packages to database.
