摘要
为了能够对不同阶段、不同类型的电离层数据及其衍生产品进行科学的管理和有效的共享,在分析电离层数据资源内容及特点的基础上,提出了电离层数据库概念模型并设计了5类21个数据表.进一步设计了电离层数据库管理共享系统的逻辑层次和功能体系,以及核心元数据标准.在J2EE环境下,利用JSP等编程语言开发实现了电离层数据库共享系统.系统可根据各类电离层数据间的关系为用户提供多种方式、相互关联的数据查询、数据在线浏览、电离层报表和变化曲线图表自动生成等功能.
Aiming at managing and sharing the ionosphere data and its derivatives of different stages and different types, the content and characters of ionosphere data are analyzed, a conceptual model of ionosphere data and 21 data tables of 5 categories are proposed. Furtherly, the logical architecture and functional system of the ionosphere database management and sharing system are designed, and the core metadata standard of ionosphere data is developed. The system is realized under J2EE environment using programming languages such as JSP. It provides users with various data querying modes according to the relations among types of ionosphere data, and also with many other functions such as online data viewing, automatic generation of data report and statistic figure.
