建立企业Intranet主要涉及两个重要方面———大量信息的组织表示和信息访问安全控制。将各类信息抽象成用基本属性和扩展属性表示的对象。这种对象技术的信息表示形式大大提高了Intranet信息组织的灵活性和通用性。同时利用基于部门、角色和用户的人员管理模式,并将对象属性访问控制进行安全分级,为关系型数据库中的信息安全提供字段级控制。 The establishment of an enterprise intranet mainly involves two important aspects: the organization of a large amount of information and the security of information access control. Abstracts all kinds of information into objects represented by basic attributes and extended attributes. The informational representation of this object technology greatly enhances the flexibility and versatility of Intranet information organizations. At the same time, it uses the personnel management mode based on departments, roles and users, and grasps the security of object attribute access control to provide field-level control for the information security in the relational database.
