摘要
将集中数据库中的多级事务模型引入多数据库中，使之成为两级事务模型．分析了一种提交协议：局部数据库的全局子事务先于全局最终决定提交，简称先提交协议．指出先提交协议十分适合两级事务模型。
We have introduced multi level transaction model, used in concentralized database, becoming two level transaction model in multi database. A commitment protocol is analyzed. Sub transaction in local database is committed before global transaction final decision, named before commitment protocol, figured out the protocol suitable for two level transaction model, and achieved high concurrency.
