METHOD AND SYSTEM FOR PERFORMING CONCURRENCY CONTROL IN A RELATIONAL DATABASE

摘要

The present invention relates to a method and a system for performing concurrency control in a relational database. A checklist of read and/or write events served during a transaction is generated, and concurrent checklists are analyzed to determine whether they can be serialized. The transaction is then commited based on the result of said analyzing step. Thus, nothing is written to the database by the transactions when they obtain elements from the database, such that concurrency control is possible for system employing a copy-on-write policy.
