Over-optimistic concurrency strategy research about relation database
关系数据库的超级乐观并发控制策略研究
To counter the dependable and real-time question of data, presents a method for that is applied to real-time transaction concurrency control program control mechanism in real-time relation data base management system where data is communicated between the program control user exchanged machine and personal computer.
针对程控用户交换机与PC机通信数据库中对数据可靠性、实时性要求，提出一种实时关系数据库管理系统中实时事务并发控机制在程控用户交换机与PC机通信中应用的方法。
The main contents and innovations of this thesis are as follows: Firstly, the paper researches the concurrency control mechanism on data of relation, and proposes a new concurrency control mechanism based on main memory? Adaptive Optimistic Concurrency Control Protocol ( AOCCP).
具体工作和创新点如下：（1）研究了基于主存的表数据并发控制机制，通过对原始的乐观并发控制协议的分析，提出了一种自适应的乐观并发控制协议。
