并发控制实现方法的比较研究*

Concurrency control is one of key technologies in DBMS, and directly impacts the correctness and performance. This paper compares the two databases PostgreSQL and InnoDB from bottom to top, and discovers that the InnoDB has more advantages in concurrency control than PostgreSQL. Last, the author does some improvement based on PostgreSQL, and then supplies detailed experiment data.
