The styling and data mapping facilities of JViews Diagrammer allow you
to connect to data sources and to style their representations.
The role of the diagram data
source is to load the data to display in the diagram, and
possibly write back the data if it has been modified.
There are the following predefined types of
data source: flat files (in the Designer only), XML, and JDBC.
When you cannot use flat files, XML, or JDBC, you can always
connect the data model to your data by implementing the data model
interface in Java™ .
