“华北克拉通破坏”重大研究计划共享数据库系统设计

The system design of shared database of the key research project on“Destruction of the North China Craton”

"华北克拉通破坏"重大研究计划共享数据系统是为了管理该计划产生的天然地震等多种类型的海量观测数据而建立,在实现对观测数据的统一管理的同时,为研究人员提供数据共享服务。基于Oracle大型数据库技术、ArcGIS技术和现代网络技术,对共享数据库系统进行了架构设计,并采用成熟的B/S结构、MVC三层架构模式和Java语言作为系统开发基础。本文对共享数据库系统架构与功能模块设计,以及系统开发体系进行了介绍。

The shared database of key research project on ＂Destruction of the North China Craton（DNNC）＂ are set up to mange the seismic data and other types of mass observation data produced by the project. The system will provide data-sharing services for researchers when it manages systematically the observation data. The architecture of shared database system is designed on the basis of the ORACLE large-scale database, ArcGIS and internet technology. B/S architecture, MVC three layer architecture model and Java program language are taken as the basis of the software development. In the paper, we introduce the sys tern architecture and function module design, and development base.
