More Information
Summary:Method and system are provided for updating data at a shared resource in a concurrent user environment. The method includes: a first client application carrying out the steps of pulling data from a shared resource for update wherein the data includes a timestamp of a last update; requesting a lock on the data only allowing updates from the first client for a set period of time; working on the data whether or not a lock is in place for the first client application. Wherein when a first client application applies to update the data, a check is carried out to compare the timestamp of the data updated by the first client application with the current timestamp of the data, and if these do not match, the update fails.
