On The Field
● 75 to 80 % , use for Report● 15 to 20%, use for analytical tools for OLAP● 0 to 5% work with data mining tools● 0 to 5% using dashboard but it's changing up
rapidly
Reporting Architecture
Web-Based ReportingWeb Ad Hoc Query and Reporting Client (WAQR)
Practical Uses of WAQR
● Export Data● Quickstart Report
Tips
We can change the report template in the following folders : pentaho-solutions/system/waqr/templates

Pentaho Report Designer
● There are two type of report writers :● Banded (divide a report in one or more groups of
data where report elements can be placed) → PRD ● Flow oriented (allow for a more free-format
placement of elements on a page)
PRD REPORT FILES
A PRD report is stored as a .prpt bundle file. This bundle contains a collectionof XML files that define the report. The layout.xml file contains all thelayout information, whereas the *-ds.xml files contain the query definitions.Beware that when a plain JDBC connection is used, passwords are stored asplain text. It’s better to use JNDI connections and let the server handle thesecurity definitions.
The PRD Screen
Two ways of building a new report :
• The New option (or Blank Report in the Welcome screen) creates a new, empty report for you.• The Report Wizard takes you through the four steps needed to create a complete report.
