Problems solved by technology

However, due to the massive amount of data stored in the OLAP system, although the multi-dimensional analysis of data in OLAP makes the data have certain logical relationships, these logical relationships may not match the user's query conditions, so , in order to ensure the integrity of the query data, it is still necessary to query each piece of data, so the amount of data to be queried is still very large. When performing related operations matching query conditions based on such a large amount of data, the huge amount of calculation will make The response time of the query is prolonged, which eventually leads to low work efficiency in obtaining query results

Embodiment Construction

[0058] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0059] The embodiment of the present invention provides a data query method based on precomputation, such as figure 1 As shown, the method obtains the query results that meet the user's query requirements by preferentially querying the pre-calculated result table, and reduces the query amount and related calculation amount required for the user to query the original data table. For this, the embodiment of the present invention provides the follo...

Abstract

The invention discloses a data query method and device based on pre-computation, and relates to the technical field of data processing, which improves the working efficiency of data query. The main technical scheme includes: when a query request is received, analyzing a query condition contained in the query request; judging whether a preset query condition matched with the query condition existsin a pre-calculation result table or not, wherein a plurality of preset query conditions and a query result corresponding to each preset query condition are stored in the pre-calculation result table;and if yes, extracting a first query result corresponding to a preset query condition matched with the query condition from the pre-calculation result table. The method is mainly used for optimizingthe data query method.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a pre-calculation-based data query method and device. Background technique [0002] With the advent of the era of big data, based on the characteristics of scale, high speed, diversity and ubiquity of big data, by quickly acquiring, processing and extracting valuable and diverse transaction data and analyzing them , can provide targeted suggestions for the operation strategy planned by the enterprise. According to this, the business value based on big data analysis is immeasurable, and the subsequent data warehouse, data security, data analysis, data The commercial value brought about by technologies such as mining and other big data has gradually attracted the attention of people in the industry. Among them, the online analytical processing system (Online Analytical Processing, OLAP) is the most important application of the data warehouse system, which realizes the mult...
