论文详细论述了三层结构方法在本课题上的具体应用形式和实现过

程,并对实现中遇到的一些问题给出了适合本课题的解决方案和架构改进

方法,比如用户接口层接口协议的设计,中介层的元数据信息的管理策略,

这其中主要包括元数据信息格式的统一策略,元数据信息的提取和更新策

略等"还有中介层数据访问过程中的结果数据暂存与返回策略,底层数据

源层的数据库连接策略等"这些策略对于以后的相关领域研究都有一定的

参考价值"

-The paper discussed in detail the specific application in the form of the three-tier structure in the subject and the realization of the process, and realize some of the problems encountered in the given solutions and architecture improvement method for this topic, such as the user interface layer interface protocol intermediary layer metadata design, information management strategy, which includes the results of a unified strategy for metadata format, the metadata information extraction and update policies, " there is an intermediary layer data access process data is temporary and return policy database connection layer of the underlying data source strategies, these strategies for future research in the field has a certain reference value "
