摘要： 提出了新颖的实时数据库事务并发控制方法：语义多版本并发控制协议(SMVCC)。利用实时数据库中存在多版本数据的特点，考虑实时数据和实时事务语义，结合实时数据库相似性概念，对传统多版本并发控制方法进行扩展，对不同事务采用不同并发控制策略，提高了事务并发度。

Abstract: This paper presents a novel concurrency control method for real-time database transactions: semantic multi version concurrency control protocol(SMVCC). It utilizes semantics of real-time transactions and multi version data in real-time databases to manage different transactions with different policies according to view consistency, and as a result, SMVCC gets more concurrency performance.
Key words:
