Richard (rsag),
The database will not get corrupted if you use AC the way it is supposed to be. That is if you are not changing registry of Operating systems. I guess you are not changing it.
The SQL database is robust enough if it is used the way it should be. An example of database corruption is, if two users accessing a patient record from the same computer at the same time (remotely) as described in the earlier posts. Where the record gets locked by the two users indefinitely and no one can access it.
What we call in the software development world is 'Unethical way of software implementation or development'. To fix this kind of DB corruption you need to get help from an SQL DBA (Database Administrator) which is not free (Hourly rate + travel expenses).
I guess, Richard you are safe.
Thanks.
