Abstract: Traditional import methods in the system with complex object-relations always encounter the problems, such as date type conversion, data consistence, object import orders and so on. This paper proposes a general data import algorithm based on object relation, which converts the 2-dimensional data into XML object descriptive format by object-relation transform and imports XML objects data by following the prearranged order.

摘要： 传统的数据导入方法在面对复杂对象关系系统时，存在原始数据到对象关系转换、数据一致性和对象导入次序确定等问题。该文提出一种基于对象关系的通用数据导入算法。借助原始数据文件对应系统中的对象关系，采用基于对象关系的数据转换，实现二维关系数据到XML对象描述格式的转换，按照一定的对象顺序将XML对象格式数据导入到系统中。
