In the traditional process of set operations, the elements of set are usually represented through natural language rather than formalized representation, and current representation has affected the efficiency of set operations. In order to solve this problem and improve the efficiency of set operations, this paper innovatively introduced the binary into the process of set operations,proposed the concept of "Set Attribute Code",and defined a series of operation rules a-bout "Set Attribute Code". All the above formed a relatively complete and formal computing system of "Set Attribute Code". Based on above theory of "Set Attribute Code",this paper proposed a series of related algorithms, which demonstrated the correctness of the theory of "Set Attribute Code". Experimental results show that the process of set operations can be achieved through 0,1 operation in the theory of "Set Attribute Code" and related algorithms. And the target of query operation was successfully achieved, which is very important in the database through the mechanism of "Set Attribute Code".%在传统的集合运算过程中,集合内的元素一般通过自然语言表示,而不是形式化表示,这就在计算机处理时影响了集合运算的效率.为了解决这个问题,将二进制引入到集合运算过程中,提出集合特征码的概念,并定义了一系列的集合特征码运算规则,从而形成了一个较为完备的、形式化的集合特征码运算体系.在上述集合特征码的理论体系下,提出一系列的相关算法,从而在算法的层次上实现了集合特征码的理论体系.实验结果表明,通过集合特征码理论及相关算法,集合运算可以通过0、1运算快速实现,并且其成功实现了数据库中的查询操作.
