Concurrency control for multiuser editors (abstract)

The concurrency of transactions executing on atomic data types can be enhanced through the use of semantic information about operations defined on these types. Hitherto, commutativity of operations has been exploited to provide enchanced concurrency ...

Multi-versioned database systems have the potential to significantly increase the amount of concurrency in transaction processing because they can avoid read-write conflicts. Unfortunately, the increase in concurrency usually comes at the cost of ...

Correctness of concurrent executions of multiple database transactions is assured by concurrency control techniques. Performance analyses, e.g., [Agr85], show that optimistic concurrency control techniques perform more efficiently than pessimistic ...
