| 中文摘要:研究如何设计一个集成高校各部门之间异构数据源的数据交换平台。本着方便、适用的原则，经过多方比较，最终确定使用虚拟视图法中的Wrapper/Mediator系统方式进行设计，即在不同的数据源上增加一个XML中间件层，实现异构数据源与XML的相互转换，同时保持它们之间的映射关系。当用户提出请求，系统就将用户的请求组织成XML文档，提交给XML中间件层，用户对数据的访问通过XML中间件层的“虚拟数据库”实现，最终达到数据集成共享的目的。 |

| Abstract:This article introduces how to design a data exchanged platform what Integrates heterogeneous data of university departments. With convenient, applicable principles, after careful comparison,the article finally uses theWrapper / Mediator systems method of virtual view to design,that adds an XML middleware layer on different data sources, realizes heterogeneous data sources and XML conversion,and keeps the mapping between them.When the user requests, system will organize the user’s request into XML document, submit to the XML middleware layer. User access to data through the “virtual database” of XML middleware layer, ultimately achieve the purpose of data sharing and integration. |
