INFORMATION PROCESSING METHOD AND APPARATUS

An information processing method for maintaining, in a system in which each of a plurality of client processes, connected via an information transmission medium, holds and uses shared data to be shared by the plurality of client processes, consistency of shared data held by the respective plurality of client processes, includes a holding step of holding the shared data, and a first issuance step of issuing, in response to a manipulation event request, a manipulation event that represents the manipulation to the shared data to the server process. In addition, a first manipulation execution step executes a manipulation to the shared data in response to a manipulation event received from the server process, and a second issuance step issues an issuance inhibition event to the server process. An inhibition step inhibits issuance of the manipulation event in the first issuance step after the issuance inhibition event is issued in the second issuance step until an event corresponding to the issuance inhibition event is received from the server process.
