This lesson shows how to create a BIRT report design file
for a model report.
You use the Report Explorer view to create a new UML report.
You start with a template that populates the report with a data source
for the UML metamodel and some standard data sets.
Data sources
and data sets provide the data for BIRT reports:
- A data source specifies where to obtain the data. For model reports,
the data source is a set of models. You can use metamodels, instance
models, or both.
- A data set specifies the data to use in the report. For model
reports, each data set is a table of data that is extracted from a
data-source model. A data set consists of two parts: a "row-mapping"
part, which finds the model objects for the rows of the table, and
a "column-mapping" part, which finds attributes of the model objects
and organizes them as columns. Both the row-mapping and column-mapping
parts contain XPath expressions that use the metamodel structures
to query a target instance model when you run the report design to
generate a report.
