ABSTRACT:
Object level conflict detection is provided. In an optimistic concurrency embodiment, when an object is to be updated, the database system is checked to determine whether any data related to fields of the object have changed since the object was read. This can be accomplished by storing a copy of the data when the initial object read function is performed and subsequently comparing the initial copy with the database data as it stands when the update is to be performed.
