In this thesis, we have proposed the algorithms of performing of three improving types, can improve the efficiency of prospecting of the unusual fluctuation database , so the improvement type of a thesis performs algorithms and will not need to rescan the whole database each time when there are newly-increased materials, the majority only needs to scan the newly-increased trade materials, in order to improve the efficiency of prospecting.

在本论文中，我们提出了三个改良式的演算法，第一个为Apriori演算法来动态探勘，其二为使用布林演算法为基础进行动态探勘，最后为以布林运算为基础之FP-tree的动态探勘，可以提升异动资料库的探勘效率，因为在过去的资料探勘技术中，在探勘关联规则的过程}式演算法当有新增资料时将不用每次都要重新扫描整个资料库，绝大部分只需要扫描新增的交易资料，以提升探勘效率。
