【摘要】 为了有效地管理复杂多样的地质矿产数据,提高地质矿产数据的安全性,本文对地质矿产数据进行整理和分析,提出了综合地质数据模型。在此基础上,基于角色访问控制思想设计了综合地质数据的安全模型,并在ORACLE数据库和所开发的综合地质数据库管理系统中实现了该安全模型。更多还原

【Abstract】 In order to effectively manage geological data which is complex and diverse and improve its security,the general geology data model was proposed after sorting out and analyzing geological data.On this basis,the general geological data security model was proposed with role-based access control(RBAC)ideas.Then the security model was realized in the ORACLE database and in the general geological database management system.更多还原
