2 . the xpath query based on global schema is decomposed into many queries based on local schema , and xpath will be mapped into sql and then results from data sources will be transformed into xml . 3 2 .将基于全局模式的xpath查询分解为针对个局部数据源的查询,同时介绍了将xpath查询转换为关系数据库所能执行的sql查询,并且描述如何将查询结果转化为xml格式。
The main contributions of this paper are as follows : 1 . presents a platform framework based on xml for data integration in water resources domain : this platform framework adopts mediator - wrapper architecture and takes virtual view method 设计一个基于xml的水文数据集成平台框架:本文以典型的mediator - wrapper体系结构为平台框架结构,采用虚拟视图的方法,用xml描述局部数据源视图。
The main work of this paper is as follow : 1 . xml schema is used to express the schema of all data source , and the heterogeneity will be found by comparing the xml schema , then the global schema will be received by eliminating the heterogeneity , finally the mapping rule between them is generated 本文的主要工作如下: 1 .采用xmlschema描述局部数据源数据模式,比较xmlschema描述的局部数据源的数据模式,找出它们之间的差异并通过一定算法消除差异得到全局模式,同时还得到局部数据源数据模式与全局模式之间的映射关系。
It gives the description of an existing system finished based on the analysis above , which deals the global data and the local data with three kinds of methods which include : processing directly with relational data ; first changing it into object type then storing it into oracle database with some modal data which can not be classified into relational data ; and to some data which is not easy to change into object type , integrating it through open i - deas " s object oriented interfaces based on corba 该系统对oracle数据库系统管理的全局数据与大型cad软件i - deas管理的局部数据分为三种情况进行的集成处理:对关系型数据直接进行集成;对部分非关系型模型数据先进行对象化,再按照oracle中对象类型数据的方法进行存储集成;对于难以对象化的模型数据,通过openi - deas提供的公共对象请求代理体系结构corba对象接口进行集成。
