摘　　要：持久化是一种存储对象的状态信息和行为信息以备以后使用的机制。明确了持久性、持久对象等概念,说明了与对象类型无关的正交持久性概念,详细阐述了正交持久性遵守的3个基本准则,即正交性、完整性、独立性的内涵;借助支持正交持久性的扩展Java语言和Java对象,对3个准则的提出依据、表现和应用进行了分析。Persistence is a mechanism for storing an object now and using it later. Based on concept of persistence, orthogonal persistence in which persistence is identified as an orthogonal property of data was described. Three principles oforthogonal persistence, orthogo-nality, completeness and independence, were discussed on application and consequence by orthogonally persistent java in detail.

关 键 词：持久性 持久对象 正交性 完整性 独立性
