Modification conflict and status of the record

When using an application in network, conflicts may occur because of conflicting data entered by the different users. For example:
1. The user X edits the form for the "California" state.
2. The user Y edits the form for the "California" state.
3. The user X renames the state to "California_01".
4. The user Y modifies the name of the state and saves it. A modification conflict occurs during this backup.
A conflict of modification status occurs when the form is deleted by the user X for example.
The different cases are presented in the table below:
