Effective complex report parsing engine and parsing method thereof

Abstract

The invention provides an effective complex report parsing engine and a parsing method thereof. One-by-one dynamic parsing can be performed according to a data source, an aggregate function, a grouping function, a calculation expression, an attribute expression, a display expression, a statistical graph expression and the like configured in a report template rule through grouping algorithm parsing, multi-source crossover algorithm parsing and dynamic inter-chip parsing, so that the effective complex report parsing engine of data acquisition, grouping, summary, inter-chip data calculation, statistical graph data drilling and the like of a report is finished. A calculated data report can be finally generated by the engine method. A report required by a user can be rendered by sending the data report to a front-end report display tool and can be exported. The application requirement of manufacturing a complex report without programming is met.

Description

technical field [0001] The invention relates to the field of computer report processing, in particular to an efficient and complex report analysis engine and an analysis method thereof. Background technique [0002] Reports are used to dynamically display data in forms such as tables and charts. Before computers, people used paper and pens to record data. A notebook, and then sum up and calculate every month. In this case, the report data and the report format are closely combined, and they are all in the same notebook. Data can only have one form of representation, which can be understood almost only by people who keep accounts, and this form is difficult to modify. [0003] When the computer appeared, people used the functions of computer processing data and interface design to generate and display reports. The main features of the report on the computer are data dynamics, diversified formats, and the complete separation of report data and report format. Users can only ...

AI Technical Summary

Problems solved by technology

In addition, the report style in China is very complicated, and a report designer with a smaller layout granularity and more flexibility like Excel is needed

For all the above reasons, Chinese users choose to give up the striped reporting tool of Crystal Reports

[0015] 3. Deployment of Crystal Reports requires an independent server

To design such a report, it usually takes a lot of time and effort to write cumbersome codes, and the report calculation rules may change constantly during the user's use, and developers have to modify the code repeatedly, which makes the system more and more complicated. It ended up being an unmanageable mess

In order to adapt to changes in user needs, developers have to consider secondary developers to redesign, which will cause a lot of duplication of labor and waste of resources, and poor reliability and difficult maintenance
