That bring out some other concerns:
What do you do if the person that started the modification goes to lunch while his record is still not saved?
What if the application need to be accessed by the web?
If you move the database to SQL Server (or another DB), you will have to implement your own pessimist locking rule, since you cannot lock a record in SQL Server (AFAIK).
I guess the only good answer will be given by the business rule of the client.
>How exactly do you "deal with contention issues"? If two people are allowed to edit the same record, and they both make a bunch of changes, what's the fair way of deciding who gets to keep theirs? Seems easier to me to just not allow a person to edit while someone else is... Unless I'm missing something?
