当您首次为一个信息集合构造一个xml模型时,通常应将这个信息集合定义为一个元素集合并使用属性来改进这个元素结构。
When you first construct an XML model for an information set, it's often useful to define the information set as a collection of elements and refine the element structure with attributes.
SDO有一个很重要的特点就是使数据操作变得更容易了,因此一旦构造好一个数据图,很重要的一点就是需要使用SDO API来遍历树结构,并访问其中的元素。
An important part of SDO is to make data manipulation easier. So once a data Graph is constructed, it is important to be able to traverse the tree and to access its elements with the SDO API.
如何构造元素的结构是与构造组成关系数据库的列和表同样重要、复杂而且可能非常困难的设计问题。
How you construct models for elements is just as important, complex, and potentially difficult a design question as how you construct the columns and tables that comprise a relational database.
