A first method includes requesting a modification of a data object within the data store using a first application process, establishing a read lock on the data object, initializing an object monitor adapted to detects changes to the data object and releasing the read lock, allowing other concurrent processes to write to the data object, wherein the object monitor detects if any of the concurrent processes overwrite the data object. A second method includes requesting a modification of a data object within the data store using a first application process, establishing a read lock on the data store, initializing a datastore monitor adapted to detect changes to the data store, reading all data objects in the data store and releasing the read lock on the data store, allowing other concurrent processes to write to the data store wherein the datastore monitor detects if any of the concurrent processes overwrite one or more data objects in the data store.
