Prototyping the application with the designer
If you are starting a project and you want to prototype your application rapidly, you will probably adopt the fastest way of populating the data model.
JViews Diagrammer offers a prebuilt in-memory data model that you can populate manually in the Designer or programmatically, or that can be populated from XML or text (CSV) files through data sources. Another prebuilt data model is available that can be populated from a database using the JDBC data source. If you can use JDBC, XML, or a flat file, you can directly import your data into the Designer.
When you consider services for populating and setting up the map diagram, there are two cases:
If your application data is compliant with one of the
JViews Diagrammer data sources, you can easily populate the data model using the data source facility or using the API.
If your application data is not compliant with one of the
JViews Diagrammer data sources, you should probably create a sample of your data in an XML file or in Microsoft® Excel®, to emulate your data.
As soon as you can populate the data model, you can display the map diagram using the default style sheet. Then you can define your own styling to create specific representations.
When you develop the operational application, you can still use the in-memory data model and one of the data sources provided with JViews Diagrammer. This may imply that your application can generate an XML file that JViews Diagrammer can read or that you use XSL-T to transform your application's XML format.
If your application data is in an object model, you can implement the data model interface of JViews Diagrammer to map your object model closely to the data model of JViews Diagrammer. This approach requires more development, but it prevents any data duplication, and ensures perfect synchronization between the data and the graphics.
