| 摘 要： | 分析了P_schema存储方法存在的问题,提出了改进的P_schema存储方法;通过引入DOM树,使嵌套结构等价于DOM树节点的父子关系,用filiation表存储节点的父子关系;由于多次引用元素结构信息相同,所以存储在同一关系中,用其外键表示引用关系,解决了P_schema存储方法中的一些难题,如嵌套和多次引用元素存储问题.

| Abstract: | An improved storage method of P_schema is brought forword by analysing problems existing in storage method of P_schema.By aid of DOM tree,nesting structure is equal to paternity of node,filiation table is used to store paternity of node.Because structure information of an multi-citing element is same,they are stored in same relation table and its foreign key is used to denote citing relation.Some difficult problems in storage method of P_schema,such as,storage of nesting element and an multi-citing element ... |
