In order to improve the speed of mining and searching ORACLE data in hybrid architecture, this paper proposes a new method based on frequent itemsets association rule mining. To construct the internal mapping associated attribute relationship model of ORACLE data in the heterogeneous network, hybrid structure Graph OLAP data warehouse model using the database relational dimension table construction, extracting the characteristic parameters of expression feature information of the ORACLE data cable through the method of homomorphic tags fast lookup to locate the target detection data. The simulation results show that using the method of ORACLE data to find the precision and recall of high calculation speed, it has better performance than the conventional method.
