Hi Terence,
If that would be able in certain form to be thus.
Nevertheless, it keep in mind that the databases are prepared to process a great number of transactions in real time without greater problems.
Alone they require a lot of memory in the server (to more more comfortable memory they feel they!!!)

.
One of the large advantages exactly to work with databases systems is that they guarantee the integrity of the data, which implies that if a transaction that involves we say 10 different tables, itself complete if all the tables have been brought up to date with said transaction, performing a rollback if some of the updatings in the different tables to failed (that is to say returns behind all the updatings that performed), not permitting that remain data of a transaction kept in partial form.
The data avoid effective way in the database, when all the tables have been able to be brought up to date in a correct way; recently just then is performed the "commit" in the database.
That of course depends on the codification in the system that you are running, but a good codification should be assured to perform the rollback or commit as correspond.
Regards
Alejandro
