Abstract
A cache synchronization method and apparatus for a distributed application having a client side, a server side, and an object located on either the client side or the server side are disclosed. The cache synchronization method may include detecting initiation of a transition to a new state on the client side, locating data on the client side that is to be synchronized, synchronizing located data using a cache synchronizer interposed between the client side and the server side, and completing the transition to the new state on the client side. The cache synchronizer may include a client side application usage specification (AUS) manager and a server side AUS manager. The cache synchronization method may also include synchronizing data in the object by passing to a database changes made locally to the object and allowing the distributed application to transition to a new state when synchronization is complete.
