Database update conflict resolution

I have a requirement where I need to build an approval process to update the database tables. I am building a web application in struts 2 and planning to use activiti as a backend engine via REST api of activiti. I would like to understand if activiti has a built in conflict resolution process that will stop 2 users from updating the same DB values via 2 change requests.

1. User A creates a change request C1 to update database table field FLD_VALUE.
2. User B creates a change request C2 to update same database table field FLD_VALUE for same record.

How can activiti detect this as a conflict and flag these 2 change requests as conflicting? Thanks.
