Abstract
Systems and methods to implement optimistic locking in online and offline environments are provided. A particular method includes receiving from an application an application data request related to retrieving a data item from a data store. The method also includes sending an optimistic locking information request to the data store to retrieve optimistic locking information, such as an identifier, associated with the data item. Additionally, the method includes receiving a data item update statement from the application while a connection between the application and a database server coupled to the data store persists or after a connection between the application and the database server has terminated and reconnected. The data item update statement relates to storing an updated version of the data item at the data store. Further, the method includes synchronizing the data item with the updated version of the data item based on the optimistic locking information.
