The report engine originated from the principle of popular workflow engine, the definition of report format, various algorithms of report content, and the idea of generating report engine.
It mainly refers to the process operation principle of the workflow engine. Based on the original data, it defines the report format and report algorithm, automatically performs calculations according to the defined algorithm, and outputs the calculated results, and then displays them according to the defined report format The content of the report.
The report engine automatically runs under the trigger of manual or schedule according to the defined report theme and its algorithm. The report engine extracts the original data based on the original data of the database according to the report theme, and performs automatic calculations according to the defined report algorithm; in the process of extracting report themes and algorithm calculations, the report engine implements various parameters according to the definition The required operations.
The data information output by the report engine is interpreted through the report interpretation interface. And generate the corresponding report to show to the user. Users can also adjust the definition language of the report theme and algorithm at any time according to actual needs. When the report engine is re-run, the report engine immediately processes the defined content and generates the changed report data. In this way, the report engine can follow the changes of the user's needs, and the required maintenance is very small, and it is also very simple and flexible.
For the output format of the report, define the required report format in the output interface of the report engine; when the user prints the report, the report engine prints the required report according to the defined format; at the same time, if the user needs to change the report style, you can Very instant and flexible redefinition to meet the various needs of users.
