New Report Design - 2009

Introduction

The components/modules that are using Report engine are: Dashboard, Monitor, Tabulation Script, Report Viewer, Diagram Viewer. These modules send request of generation to report engine including:

• A data cache which contains all source data
• Stylesheets (including external and inline stylesheet) to apply
• Kind of presentation that the report should be exported as (pdf, excel, ppt, word, html, image)
• Other kinds of settings

The report engine takes the request, make calculation using the Interpreter, and then export the result into desired format.

A report consists of elements like: diagrams, images, text blocks, pages, paragraphs. The most important element is Diagram, which can be discriminated based on:

• Data
  • Cross Diagram
  • Standard Diagram
  • Tracking Diagram
  • Campaign Diagram

• Presentation type
  • Table chart
  • Image chart which include many kinds of chart like: pie, bar, line, funnel, area, radar etc.

Concepts

• Diagram
• StyleSheet
• Tabulation Script
• Data cache
• Diagram viewer
• Report viewer
• Dashboard
• Monitor

Why a new system?

Current system drawbacks

• Heavy XML processing
• Heavy code duplication
• Inconsistent generation process

Thus it makes the cost of fixing bugs and maintain the old system greater than the cost of making an new system.

New system goals

• Remove the drawbacks of current system
• Side by side working with the old system
• Fully unit testing
• Unit/Integration tests can be run automatically
• Testing API must be simple enough for testers to join writing test cases
• Report API must be keep as simplest as possible

Design details

• Report unit testing system
• Diagram generation process
• Tabulation Script
• Tabulation Script for setting inline style to Table Chart
• Diagram viewer control
• Report viewer control
• Integrating with Dashboard
• Integrating with Monitor

Current implementation status

• Report unit testing system: rather complete and testers have joined writing a lot of test cases

• CrossDiagram

• Support for one column/row axis
• Cell types

• Presentation type

• Support Nevron image chart

• Tabulation Script

• Support for createCrossDiagram
• Support for setting inline stylesheet

• Diagram viewer control

Next action

• Report viewer control
