I think best practice is to ensure that the locks are as minimal as possible, both hen users are accessing the data and when you are writing it.
 
It may be that you need to consider to READ UNCOMMITTED or NOLOCKfor example. This web link shows that no shared locks are issued or exclusive locks are honored.

A simple UPDATE command should do it but don't forget that if the user is viewing the data at the same time that it will need to be refreshed or else it will deal with old data.
