DBMS level access control: Each tenant accesses his dedicated database or table schemas with his dedicate account via leveraging DB2 security features like lattice-based access control ( LBAC). DBMS级访问控制:每个租户通过lattice-basedaccesscontrol(LBAC)等DB2安全特性,使用专用的账户访问专用的数据库或表/模式。
It describes the fuzzy PID-type controller design of the alkali boiler water level, the build of 2-D control table, the realization of the computer design and simulation of the controller. 以碱回收炉的水位控制为例具体论述调整系统控制量的模糊PID控制器的设计、2-D控制表的建立、以及控制器计算机设计与仿真的实现。
Computer fuzzy control with control table may reduce the level of memory size and computing speed. Control table can be off-line gained by fuzzy rules. 通过控制表实现计算机模糊控制,可以降低对计算机内存容量和速度的要求,控制表根据人们对控制对象的认识和操作经验确定的模糊控制规则离线处理。
By utilizing the user management model of based on department, role, user and ranking security level of each attribute of object, we can control access to each field of table of RDBMS in intranet system. 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。
Field level data security control in the Oracle was realized with sub table of field. 使用了字段子表,在Oracle内实现了字段级数据安全控制;
