非功能性的要求安全是一个非常重要的问题,特别是在特权换句话说如果权限可以自由地给予,这是可能的,数据可以由任何用户扭曲如果是这样的话系统的可靠性大大下降,可以不做这些任务上课时间,因此基于安全的非功能性需求权限可以通过以下方式
        As mentioned on non-functional requirements, the security is a very important issue especially on privileges. In other words, if the privileges can be freely given, it is possible that the data can be distorted by any users. If so, the system credibility will be declined significantly as well as can not do with these tasks on class schedule any longer. Hence, based on the non-functional requirements on security, the privileges can be given in the following ways:
 
        For timetablers: They can lookup and edit all data as well as schedule classes but these classes and data have to be related with their own faculty. Otherwise, they may lookup the information related with other faculties but have to be unable to change anything. All timetablers can be given the http://www.51fabiao.org/dxassignment/rights to check the room and tool availability.
They can also look some student details if these students are taking a unit from this faculty.
 
        For lecturers and students: They can check their own timetables but can not be able to change anything. They have no access rights for anything else.
