Problems solved by technology

[0006] The problem to be solved by the present invention is: for the structural type data generated in the real-time monitoring environment, instant storage and fast and efficient access and analysis of the stored historical data are required, and a large amount of historical data must be stored in a limited physical storage space. At the same time, it is also necessary to consider that data can be stored and accessed quickly. The existing real-time data storage methods cannot meet these requirements, and are easily affected by data length and compression efficiency, making the overall storage efficiency not ideal.

Embodiment Construction

[0046] The present invention will be further described below in conjunction with the accompanying drawings.

[0047] figure 1 and figure 2 It is a flowchart of a method for storing structure type data of a real-time database in the present invention. Include the following steps:

[0048] 1) Decomposition by field: Obtain historical data from the structural data buffer queue, decompose all fields of the structural data into tags of the real-time database, and each field corresponds to a unique tag ID in the real-time database;

[0049] 2) Store by field: perform historical data storage processing on all historical data in the tag ID input cache corresponding to the field;

[0050] 3) Field processing completion judgment: check whether the tag ID corresponding to each field of the structure has been processed, if completed, perform step 4), if not completed, return to step 2);

[0051] 4) Data processing completion judgment: check whether the acquired historical data has co...

Abstract

The invention relates to a structured storage method of data of a real-time database, which comprises the following steps: 1) decomposing by field; 2) storing by field; 3) judging whether field processing is completed; and 4) judging whether data processing is completed. By decomposing structure type data into labels of the real-time database, and enabling them to form one-to-one correspondence, the invention can realize the separate storage of each field of the structure type, thereby shortening the length of single data and reducing the influence of a single record on the system performance. After carrying out exponential decomposition and replacement on floating type field values, the invention can obtain a high compression efficiency because of the compression of data by the real-time database and can especially obtain an ultra high compression ratio by using a sequencing linear fitting method, thereby achieving the purposes of high-efficiency storage and compression of the structured data and having high practical application values.

Description

technical field [0001] The invention belongs to the technical field of data storage, and relates to the storage of data generated by a real-time monitoring environment, in particular to the storage and processing of large batches of real-time data composed of structures, and is a storage method for structure-type data of a real-time database. Background technique [0002] For the data generated in some real-time monitoring environments, in addition to the characteristics of huge quantity, high collection frequency, and long duration, it is also necessary to store structured data. The processing of the structural type data of these large batches of sampling points, especially how to store the real-time structural type data of the sampling points in real time, and how to quickly and efficiently access and analyze the stored structural type historical data has become a real-time The key points and difficulties of data storage technology in the structure type of database. [00...
