The artical a based on artificial immune algorithm for this potential threat to large e-commerce web database data mining methods.Computing potential threats in web database data attributes

the difference of the potential threat data obtained characteristics of artificial immune to potential threat data

in the process of immune by calculating the matching of antigen and antibody

can obtain potential threat data correlation

combined with the potential threat to potential threat data mining model is set up the correlation of data

has realized the potential threat to large e-commerce web database of data mining.Experimental results show that the improved algorithm to large potential threats e-commerce web database

data mining can improve the accuracy of mining

effect is satisfactory.
