A data query method and system

Abstract

The embodiment of the invention relates to a data inquiry method and system, and belongs to the technical field of big data. The method includes the steps of parsing a received SDL instruction throughan SDL parser in an SDL engine to obtain an abstract syntax tree, parsing the abstract syntax tree through the SDL parser in the SDL engine, calling data information corresponding to the parsed abstract syntax tree in a data warehouse through the SDL parser according to an Http protocol, and executing the operation corresponding to the SDL instruction through the SDL parser according to the datainformation and the parsed abstract syntax tree. By means of the technical scheme, on one hand, the technical defects that in the prior art, consumption cost is high, applicability is simplex, inquiryresult is not accurate enough and interference is easily caused are overcome; on the other hand, the technical effects of flexibly inquiring about data and being high in accuracy and inquiry efficiency are achieved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of big data, and in particular to a data query method and system. Background technique [0002] With the development of big data-related technologies, more and more people have noticed the huge economic value hidden under big data. If you want to engage in big data analysis, you need not only to master business knowledge but also to understand IT technology. The high requirements for analysts make them daunting. [0003] In the prior art, when the statistics data needs to be queried, there are two implementation ways. [0004] The first way is to query statistical data through a specific system. [0005] The second way of implementation is to query the statistical data through fields (or key fields). [0006] However, in the process of realizing the present invention, the inventor finds that at least the following problems exist: [0007] 1. If the query is made through the deve...

Problems solved by technology

[0007] 1. If the query is made through the development of the system, the cost will be increased, and the query can only be performed for certain specific data, and diversity cannot be achieved;

[0008] 2. If you query by field, the process is cumbersome, and it is easy to mask the required information
