Web186 4. Concurrency Control 4.1 Introduction The concurrent manipulation of shared information is an integral part of all group processes. Thus, groupware needs some sort of concurrency control in order to keep the information consistent. In the context of database systems consistency has already been explored extensively (for example permitting WebThese systems frequently require fine-granularity sharing of data and fast response times. This paper distinguishes real-time groupware systems from other multi-user systems and dis-cusses their concurrency control requirements. An algorithm for concurrency control in real-time groupware systems is then presented.
