针对基于文件方式管理的Internet化学化工资源导航系统的问题 ,结合ChIN的发展需求 ,在第二版ChIN中采用了关系数据库来管理整个导航系统。本文介绍了第二版ChIN的数据库设计和模块设计 ,着重对导航系统与用户的交互性进行分析设计 ,建立了Web用户资源提交、用户对资源投票及评价信息的提交、信息订阅与发送、全文检索与关系数据库检索相结合的站点检索等系统 ,极大地提高了ChIN与用户的交互能力 ,既有助于ChIN中所索引资源的优化与更新 ,也提高了ChIN的易用性和信息服务能力。
In view of the problem of internet chemical and chemical resource navigation system based on file management and the development demand of ChIN, a relational database is adopted in the second edition of ChIN to manage the entire navigation system. This paper introduces the second edition of ChIN database design and module design, focusing on the navigation system and user interaction analysis and design, the establishment of a Web user resource submission, the user vote on resources and evaluation of information submitted, the information is subscribed and sent, the full text Search and relational database retrieval combined site retrieval and other systems, which greatly improves the ChIN and user interaction capabilities, both to help optimize the indexing of ChIN resources and updates, but also improve the ChIN ease of use and information services .
