I have *my way* of handling this problem, but I would like to hear
how you guys do it.
Here's the problem -- let's say you have a database containing names
and addresses and you want "approved" users to be able to access the
data. As such, a user must login before accessing an editing script
that would allow them to review and edit the data -- nothing
complicated about that.
However, let's say you have more than one user accessing the editing
script at the same time and you want to make sure that any changes
made to the database are done in the most efficient manner possible.
For example, if two users access the database at the same time and
are editing different records, then there's no real problem. When
each user finishes editing they simply click submit and their changes
are recorded in the database. However, if two (or more) users want to
access the same record, then how do you handle that?
