Absolute and relative updates?

Absolute update ensures that changes to a value in a record are saved exactly as they are entered regardless of any other user updates.

User A	User B
-	User B reads the value 100
User A reads the value 100	-
User A writes the value 200	-
-	User B writes the value 200
Final Database value 200	-

Relative update can be used in multi-user environment. This allows multiple users work on the same record at the same time. Here morphX combines each of the user’s modifications before the record is saved in the data base.

User A	User B
-	User B reads the value 100
User A reads the value 100	-
User A writes the value 200	-
-	User B writes the value 300
Final Database value 400	-
