Embodiment Construction

[0015] The present invention will be further described below in conjunction with accompanying drawing.

[0016] Such as figure 1 as well as figure 2 As shown, a method for data access to the power demand side system includes the following steps: S1 encapsulates the collected client data into an object; S2 collects the client to call the interface and sends the encapsulated object to the middleware server; The S3 middleware server stores the encapsulated objects in HSQL memory database and object database respectively. The above three steps are mainly to store the object data in the middleware server.

[0017] The S4 client calls the interface to send an instruction to fetch a certain object; the S5 middleware server returns the result to the client, which mainly fetches the required object data from the middleware server.

[0018] In the step S1, after the data collection by the collection client is completed, the object is encapsulated in the collection client.

Abstract

The invention relates to the field of electric power acquisition data storage, and discloses a method for performing data access on a power demand side system. The method is characterized by comprising the following steps: (S1) packaging objects of acquisition client data; (S2) sending the objects to a middleware server by an acquisition client calling interface; (S3) performing HSQL memory database storage and object database storage on the object respectively by the middleware server; (S4) sending a command for fetching a certain object by the client calling interface; and (S5) returning a result to a client by the middleware server. The method has the advantages that the efficiency of fetching data is greatly increased and the overall performance of the system is improved through the synchronous storage of the memory database and object data, and the system can ensure the storage integrity of acquired data to the utmost extent, avoid repeated acquisition operations and improve the efficiency in a disc writing mode during data storage.

Description

technical field [0001] The invention relates to the field of electric power collection data storage, in particular to a method for data access to a power demand side system. Background technique [0002] In a J2EE distributed large-scale data application system, each application module of the system may be installed in different application servers. Abnormal network connection or abnormal application server cannot store data, which will cause the collected data not to be stored in the database in a normal and timely manner, resulting in data loss, thus affecting the integrity of data storage. Moreover, after the system returns to normal from a network abnormality or software abnormality, the system needs to perform repeated collection and storage operations on missing data, thereby reducing efficiency. Contents of the invention [0003] In order to solve the problems in the prior art, the present invention provides a method for data access to the power demand side syst...
