What is single-user mode/multiple-user mode of an application?

[Arjay]

IMO for an app (whether web based or however hosted and implemented) to be called multi-user it needs to be able to correctly handle resource/data conflicts. Therefore IMO twitter is not multi-user. It could be described as a multi-instance single-user app.

Why do you think Twitter doesn't correctly handle resource/data conflicts?

Different hashtags simultaneously updating the same data? As OReubens said in post #14, Twitter made their design in such a way to hard avoid the multiuser conflict issues entirely.

IMO of more interest is whether the codeguru web site could be described as multi-user? Or what about Amazon and **** which involves transactions???

Twitter has an easier problem vs. the problem where multiple users want to change the same field of a record. With twitter, the same hash tag gets updated, but this only adds a new list entry to the hash tag. So there never any merging of a tweet.

With regard to CodeGuru being multi-user. The scope of my interest is in coming up with a definition that satisfies the OP in the context of what they are trying to accomplish functionally or programmatically.

I'm not as interested in a one-size-fits all definition - I'll let the academics work on that.

Single-user mode limits access to your company file to one person at a time. If other people are working in the file, they must close the file or exit QuickBooks before you can switch to single-user mode.
