Method and device for improving retrieval efficiency of space science and application data

Abstract

The invention discloses a method and a device for improving the retrieval efficiency of space science and application data. The method comprises the following steps that: naming a data file to be stored, wherein the filename of the data file at least comprises at least two prefixes; when the data file is stored, through a way of filename analysis, constructing the search tree of the filename; storing one prefix of the filename into nodes except a root node of the search tree; enabling the leaf node of the search tree to correspond to the storage address of the data file; and when the data file is retrieved, through the comparison of retrieval condition and the branch of the search tree, obtaining the storage address of the data file so as to obtain the data file. The device comprises a naming module, a generation module and a retrieval module. By use of the method and the device, through a quick retrieval way of the filename, the quick retrieval of a space science and application data file can be realized, the occupation of calculation resources and storage resources is greatly reduced, so that retrieval time is greatly shortened, retrieval efficiency is improved, and user experience is better.

Description

technical field [0001] The invention relates to the technical field of space science and application data retrieval, more specifically, the invention is a method and device for improving the efficiency of space science and application data retrieval. Background technique [0002] At present, the archiving and retrieval methods for space science and application data are as follows: store and archive through the XML configuration file corresponding to the data file, and query through the database SQL statement when the user retrieves. [0003] However, the traditional method has the following disadvantages: when the data volume of space science and application data is huge, on the one hand, the computing and storage resources are becoming increasingly tense, and a large number of XML configuration files bring inconvenience to the efficient management of data; on the other hand, On the one hand, when a user retrieves a query, the associated query of multiple tables in the datab...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the problems of delay in retrieval response and high consumption of computing and storage resources existing in existing space science and application data retrieval, the present invention provides a method and device for improving the efficiency of space science and application data retrieval, which is beneficial to space science and application A standard specification is established for the file name of the data. By directly analyzing the file name and storing it in the database, the user can quickly retrieve the file name in the memory by building a trie tree of the file name when searching, and then realize the fast retrieval of the data file, which is extremely fast. Greatly improve the efficiency of retrieval operations, meet the real-time operational requirements of large-scale space science and application data, and greatly improve user experience
