The invention relates to a method for storing data based on Oracle data and Hbase data, and provides a comprehensive network management system which comprises a monitoring device, a data collector, adata processor and a data memory. The data collector is in communication connection with the monitoring device and the data processor. The data processor is also in communication connection with a data memory. The method is specifically realized according to the following steps: step S1, monitoring a comprehensive network management system by monitoring equipment; enabling the data collector to collect monitoring data in the monitoring device through an SNMP protocol opened by the monitoring device and send the collected monitoring data to the data processor; s2, enabling the data processor todivide the received monitoring data into index data and current alarm data by using an Esper complex event processing engine in the data processor, and store the two pieces of data into a data memory; and S3, enabling the data memory to store the received two kinds of data into respective databases. According to the method, the performance problems of massive data storage and query and the like of the relational database can be solved.
