Occasionally Connected Systems Architecture: Concurrency
The problem of concurrency is a familiar one in the development of multi-user systems. Most of the time, optimistic locking is preferred because it results in better throughput. However, pessimistic locking has its place as well for those cases where only one user should be allowed to work on the data. Both of these solutions break down once users start working offline and try to synchronize their updates with the server later.
