Problems solved by technology

However, the query functions in each system vary greatly, the query data is different, the filter conditions provided are different, the format of the display report is different, the column name, alignment method, data display format, height and width of each column in the report are all different. There are thousands of differences. At the same time, various reports and data export requirements
The data that the user needs to export should be a table file with the same display format as the query result of the report, which is not conducive to data processing

Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the metabase-based data processing method of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0030] Although the queries in the computer systems are very different, a common rule can still be found, that is, they all adopt a common pattern and have the same steps. Specifically, any query function must provide a query statement (may be SQL or HQL), and at the same time provide users with some filter conditions to choose from. Finally, when the query results are displayed, the system should be informed of the column names and alignments displayed in the report. method, data display format, height and width, etc. If this common pattern is made int...

Abstract

The invention discloses a data processing method based on a metadata base. The data processing method comprises the following steps: Step100, saving configuration data required by report query and data export, comprising configuration of report information, configuration of filtering conditions, configuration of report representing information and configuration of detailed information in a form of the metadata base; Step 200, when a user enters a report module, listing the report information through the metadata base for the selection of the user, providing the report filtering conditions for the input of the user, displaying query results according to a format defined by the metadata base and displaying related detailed information; meanwhile, when the user has a data export request, using the same parameters to execute query and using the same format to export a file. Through adopting the mode, development and maintenance are more convenient, the development workload is reduced, and research and development technical thresholds are reduced.

Description

technical field [0001] The invention relates to the technical field of computer data processing, in particular to a data processing method based on a metadata database. Background technique [0002] At present, there are a large number of information systems that require data query functions. After querying relevant data, they also hope to provide Excel data export functions. However, the query functions in each system vary greatly, the query data is different, the filter conditions provided are different, the format of the display report is different, the column name, alignment method, data display format, height and width of each column in the report are all different. There are thousands of differences. At the same time, various reports also require data export. The data that the user needs to export should be a table file with the same display format as the query result of the report, which is not conducive to data processing. Therefore, it is necessary to provide a da...
