A report engine provides an entry point for reporting functionalities. It is where the report generation and rendering process are globally customized. It is also the place where engine statistics are collected. Through report engine, reports can be generated and rendered to different output formats. Queries can also be executed for preview purpose without involving a full report generation.
Engine supports running different types of tasks. Example tasks include running a report design to generate a report instance file, rendering a report instance to output format, running a report directly to output, running a dataset for preview, seaching a report, etc.
