Abstract

The invention discloses a security data storage method. The method comprises the following steps: A) carrying out data combination on a data sequence incrementally downloaded to the local and a locally stored data sequence according to a time sequence; B) performing binary memory compression on the merged data sequence to obtain compressed data; C) calculating index parameter information of the compressed data; D) writing the index parameter information, a data check code from a download service and a corresponding data timestamp in an index area; And E) according to the index parameter information, writing the compressed data into corresponding data blocks, wherein the data block adopts a dynamic division mode. By implementing the security data storage method, the security data storage method has the beneficial effects of having data verification capability, being irrelevant to a data structure, being capable of realizing dynamic expansion and realizing efficient compressed storage.

Description

technical field [0001] The invention relates to the field of data storage, in particular to a method for storing securities data. Background technique [0002] The securities market snapshot data is sent every three seconds through the data information service provider interface of the exchange, connected to the dedicated receiving service program by the dedicated line, after decoding, specific business data processing, re-encoding and distribution, and finally the real-time market snapshot is transmitted to the terminal Software, historical securities data, through the download agreement between the terminal software and the distribution service, downloaded to the local, for data display and local calculation, etc. [0003] The terminal software will store the necessary securities historical data locally, which is conducive to the fast loading and display of data on the software interface, and can realize incremental data download to save data download traffic. The securit...
