PB对事务管理机制的解析与分类

The Paraphrasing and Classification of PB Business Management Mechanism

文章分析和讨论了PB对事务管理的机制,在讨论和分析的基础上,提出两个被人们忽视或教材上未发现的概念——单语句事务、多语句事务。用这两个概念将PB下的事务和PB下的SQL语句进行了分类,列举了各类事务的SQL语句的应用实例。希望这些概念和实例对于学习PB或从事PB应用开发人员能有参考价值。

This text analyzes and discusses a process of PB to the business management. In foundation of discussing and analyzing, the author puts forward two concepts which are usually neglected by people or which have never been discovered in teaching materials： the single- sentence business and the multi-sentences business, in using of these two concepts, the author classifies the businesses and the SQL language sentences under PB, enumerating each kind of applied examples of SQL language, hoping these concepts with examples could have some reference value for the study and the application development of PB.
