摘要 数据的一致性和完整性设计在数据库开发与应用中是一个非常重要的环节。Notes非结构化数据库的特性以及提供的"继承"功能仅在创建文档时发生一次等问题容易破坏数据的一致性。本文提出了同步修改的方案,并使用了文档链指针和数据库事件的定义,充分保证了Notes数据库中数据的一致性。并在此基础上讨论Notes数据库的完整性控制问题。 Introduces an efficient solution named synchronous modification,which solves the problem that the inheritance provided by Notes only happens once when documents are created.Through the restriction of synchronous modification and the use of document pointers and database events,the consistency of data in Notes database is ensured.Furthermore,this paper discusses the integrality of data in Notes.
