Viewing the relationships among files in a project
In Navigator, right-click the project, and choose Show Relationship Overview. The report editor displays a project model diagram, as shown in Figure 25-5. The diagram shows all the BIRT files in the project, and the relationships among them.
Figure 25-5  
The diagram in Figure 25-5 shows the following files and relationships:
You can zoom the diagram, print it, or save it as an image. Right-click in an empty space in the diagram to access these options. You can edit the layout of the diagram by moving objects.
You can also add notes to any item in the diagram. For example, if a report depends on a library, it would be useful to list the specific element or elements in the library that the report uses. Hover the mouse pointer over the item. When you see two arrows with boxes, as shown in Figure 25-6, click one of the arrows and drag the line to an area in which to create a note. When you release the mouse button, a Create Note Attachment button appears. Click it to create a note.

Figure 25-7 shows a note created for Employees.rptdesign. If you add notes, save the diagram as an image file or print it. The notes are lost when you close the view or regenerate the diagram.

The impact-analysis tools can be used in a BIRT project only. They are not available in other types of projects, such as Java or plug-in projects. In Navigator, a BIRT project is identified with a B symbol in the corner of the project icon.
Furthermore, the project model diagram and impact report show the file dependencies between BIRT files only, such as data objects, information objects, libraries, and reports. Non-BIRT files, such as JAR, CSS, and image files, that reports might use are not included in the project model diagram or impact report.
