摘要
XML具有与平台无关、易于扩展、交互性好、语义性强、可格式化等优点,因此,XML被作为一种数据之间的交换标准,异构关系数据库之间常采用XML作为数据交换的中间介质,基于关系模型实现数据库系统之间的数据交换,转换算法和方法已经得到快速的发展。而对于将关系系统到对象系统之间的转换研究很少,因此,针对对象系统到对象关系系统提出了一种方法,该方法可以将XMLschema转换为对象关系模型模式,同时也可以将对象关系模型模式转换为XML schema。
XML,for its advantages of platform-independent,easy to extend,good interactivity,strong semantics,and formatability,is regarded as a standard for exchanging data.XML is often used as an intermediate medium for data exchange of between heterogeneous relational databases.Algorithms for implementing data exchange between database systems based on relational models now develop rapidly,but less research is done on the transformation between relational systems and object systems.Therefore,a method for object system to object relationship system is proposed.This method can transform an XML schema into an object-relational model schema,and also convert an object-relational model schema into an XML schema.
