多层次复用系统访问权限控制方法设计与实现

摘要

To implement the multi-hierarchy multiplexing access authorization control,an approach of binary digit based access authorization control was proposed.Aiming at mutual independence feature at the same level and affiliation character between layers,hierarchy and attribute of the target was defined and the length of binary digit data was used to represent it.An approach of representation of access authorization with binary digit data was designed.This approach had been proved to be able to simplify the design of database,implement access authorization control and make the design of related program get brief and effi-cient.%为了实现多层次复用系统访问权限控制，设计了基于二进制的访问权限控制方法。针对系统同一层次对象的互相独立性及高低层次对象的隶属关系，定义了对象的层次对象属性，使用一段二进制数据进行表示；设计了访问权限的二进制数据表示方法。在某信息系统中的应用结果表明，该方法在实现要求的权限控制同时，有助于简化数据库设计，使相关的程序设计简洁高效。
