Abstract: This paper proposes a global transaction model and its serialization transaction management technique in mobile multi-database. This technique checks the serialization of a global transaction based on its global transaction serialization graph (GTSC) which is constructed based on the local serialization information got from every autonomous site. It addresses disconnection (including disconnection that represents catastrophic failures) and migration and enforces atomicity and isolation criteria of the global transaction.

摘要： 提出了一个移动多数据库全局事务模型及其可串行化事务管理技术。该技术通过从各自治站点中获取本地可串行化信息构造全局事务可串行化图GTSG来判定全局事务的可串行性。它支持全局事务的迁移、网络的断接(包括可能发生的灾难性断接)并保证全局事务的关键站点子事务的原子性和隔离性。
