● 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
5. Practical Uses of WAQR

6. 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 collection
of XML files that define the report. The layout.xml file contains all the
layout information, whereas the *-ds.xml files contain the query definitions.
Beware that when a plain JDBC connection is used, passwords are stored as
plain text. It’s better to use JNDI connections and let the server handle the
security definitions.
7. 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.
