Rational® ClearQuest® supports
data-pull reporting with BIRT and SAP Crystal Reports and data-push
reporting with SAP Crystal Reports.
Support for the data-pull reporting model was introduced in ClearQuest version
7.1. The data-pull model allows reporting systems like Business Intelligence
and Reporting Tools (BIRT) and SAP Crystal Reports to configure data
sources and pull data from these sources when the report is run. This
approach provides significant flexibility by letting you create reports
from multiple data sources and multiple data sets, and by letting
you store and manage reports with an enterprise reporting server.
ClearQuest versions
earlier than 7.1 use a data-push model to run reports. In the Crystal
Reports data-push model, you define a report by specifying a query
and a report format, both of which are stored in the ClearQuest user database. When you run
a report, the
ClearQuest client
runs a query and pushes the results to the Crystal Reports runtime
engine for rendering. The data-push model precludes reporting on multiple
data sources and multiple result sets.
