I. Description
The execution process of the report can be roughly divided into two steps: 1. Report calculation; 2. Page conversion.
Report calculation process: first read our SQL statement, transfer the complete SQL statement to the database server, and the database returns the data to the report server. The report server performs calculations such as data column expansion, summary, association, and formula calculation, and finally generates the report result.
Page conversion process: After the report calculation is completed, an XML page is generated, which needs to be converted to an HTML page to be viewed in a browser.
For this process, FineReport can be monitored in real time. The monitoring method is to set the log output level of the server to "general information", and you can see the time used in each step on the console.
