Question on record locking management

[donwiss]

I'm developing an application that is all Excel VBA Forms with the data in Access. I have no database background. I developed a record locking system not knowing just what real ones have.

This is my locking management form. There are three types of file systems, hence some blanks. The one with a blank in the Record Name column does have record nnames, but they are edited simultaneously, and so all locked together.

When I added the Last Saved column, what I really wanted to add was the timestamp of when it was locked. Of course, I could add that field to each table, and only complicate things a little.

So my question is just what does a real locking system have? If I add the lock timestamp, does anyone care about when it was last saved?

Also I do not have record IDs. My primary key is the combination of folder and file names. My pseudo-file system.

Okay guys. I surrender. Another reason for switching is to not embarrass myself when someone in the know looks at my code.

All is done and documented. There was not that much SQL code to change. And the retrieval of what files are locked is dramatically simplified. I always like to reduce the code.

So thanks for setting me straight. The end result is much nicer than what I had before.
