摘要 简单读/写锁模型对工程合作设计事务支持较弱。该文结合工程数据库的层次性,提出了基于2PL的扩充分层封锁机制,能够较好地支持工程合作设计事务的进行和提高事务的并发度。 The simple read/write locks model supports engineering cooperation design transaction little.A concurrency control mechanism of extended delamination locking based on2PL is presented,which can support the requirement of engineering cooperation design transaction and improve the concurrency degree of transaction.
