面向对象数据库系统WHYMX的单级事务并发控制的设计与实现

Design and Implementation of the Concurrency Control of Single-level Transaction in WHYMX OODB Management System

摘要: WHYMX的数据模型使得事务管理复杂化,传统的封锁法不足以解决事务并发控制出现的新问题。本文首先扼要介绍了基于封锁法扩展的单级事务并发控制协议,然后给出了对应的实现算法。

Abstract: This paper describes the design and implementation of the concurrency control of single-level transaction in WHYMX Object-Oriented Data Base(OODB) management system, gives a number of Concurrency control protocols suited to OODB, and presents corresponding algorithms.
