Example Embodiment

[0051] In this patent, the specific embodiment will be further described below with reference to the accompanying drawings and examples.

[0052] Such as figure 1 As shown, an embodiment of the present invention provides a data storage method, the method comprising:

[0053]Step S11, obtain power billing data.

[0054] In the embodiment of the present invention, the power metering system will unify the power billing data in the month, quarter or annual, and this step is collected on the finishing power billing data.

[0055] Step S12, based on the power billing data and the preset data processing logic, establish an index table for the power billing data, and store the power billing data to the number of preset data size and preset cluster machine. Configure the nodes of the distributed cluster.

[0056] Combine figure 2 The preset data size and the number of machines have been determined in the distributed distributed cluster. The distributed file storage system is established ...

Abstract

The invention provides a data storage method and system. The method comprises the following steps: acquiring power charging data; establishing an index table for the power charging data according to the power charging data and a preset data processing logic, and storing the power charging data in each node of a distributed cluster configured according to a preset data size and a preset cluster machine number; cleaning the electric power charging data, and generating structured data from the cleaned electric power charging data; mapping the structured data into an RDF format comprising points and edges of a graph and importing the RDF format into the graph database; analyzing the graph database to obtain a risk prediction result of the user; and respectively storing the risk prediction results of the user into an hbase database, a mysql database and a nebula database, and establishing an external index table of data among the hbase database, the mysql database and the nebula database. Through the data storage method and device, the problems that an existing data storage system is prone to crash and data delay, and data mining is not facilitated are solved.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a data storage method and system. Background technique [0002] Power billing data is usually automatically collected by the power billing system, such as the user's monthly electricity bill payment and electricity consumption. Among them, the system mainly records the monthly payment and arrears of ordinary users, as well as the detailed electricity bills of users every month, including information such as electricity price categories, additional fees, and meter copies. The current power billing system has been networked, and users can easily inquire about the current month's electricity consumption and expenses in the current area, as well as historical expenses. Intelligent electronic systems bring convenience to users, and at the same time, a large amount of data also brings challenges to the application management and storage methods of system data.
