The intrusion of malicious transactions is the important springhead that demolishes database system.The database management system(DBMS) is a key part in the security of the database system.Enhancing the ability of detecting malicious transactions is very important in DBMS.Based on a detecting method of malicious transactions in DBMS,an auto-generating method of legal transaction-profile chart is put forward.The integrated audit information is generated by automatic testing tool;and then audit table was index on user name and transaction number in formal audit table.Lastly,legal transaction-profile chart is generated based on generating and merging algorithm.Experiments indicate that the method has good performance and veracity.Intuitionistic transaction profile is generated.
