| 中文摘要: |
| 针对地质数据数量庞大、数据分布散乱、数据种类繁多、数据格式复杂等特点,根据线分类方法,对综合地质数据进行分类,提出了地质数据树的概念,运用了综合地质数据模型,采用关系数据库技术,建立了综合地质数据库。同时利用系统导入导出功能,从地质工作的角度实现数据的备份与恢复。将基于角色的资源访问控制(RBAC)思想引入到系统的权限管理中,提高了权限管理的效率,细化了授权粒度。 |
| 英文摘要: |
| According to characters of the geological data of huge volume,distribution in disorder,various types and complex formats etc.,the paper uses linear classification method to classify the general geological data,give the conception and model of geological data tree and establish the general geology database management system on basis of the model and relational database technology.Besides the import and export function can be used as data backup and recovery from the perspective of geologic work the role-based access control thought(RBAC) is introduced into the control mechanism,the efficiency of the privileges management raised and the authorization granularity refined. |
