In the Schema Editor, you can view any schema, tool map schema, or data file in .XML format. When you open a file, it is loaded into memory. To actually see the schema file, use the commands on the View menu to display the View dialog box.
View Dialog Box
The View dialog box allows you to select the view that you want to use to see your schema, tool map schema, or data file. The View dialog box has two modes: simple and advanced. In Simple mode, you can select the view you want from a list without setting view options.
In Advanced mode, click Options to display the View tab. The Options dialog box has multiple tabs that allow you to select a view, set options for views, set the scope for your view, and so on.
You can switch between modes in the View dialog box by clicking the Advanced button to switch to Advanced mode and the Simple button to switch to Simple mode.
Schema Editor Views
The many different views in the Schema Editor provide different types of information that help you understand how the schema, tool map schema, and data files work. For example, when you view the schema in any of the tree views, except the schema tree/UML view and the schema hierarchy views, you can typically see the schema class definitions. As you expand nodes in the tree views, you can navigate the relationships in the schema and view interface definitions, property definitions, and even instances of the class if you also have a data file open in the Schema Editor.
The Schema Editor also provides graphical views. These views allow you to see both static and dynamic UML diagrams containing the classes, relationships, interfaces, and properties defined in the file.
Viewing Multiple Objects
The following controls support multi-object viewing:
-
Tree
-
Table (hor) and Table (vert) and the other view-based tabs (at right end of multi-tab control)
-
Editable UML
-
MultiEdit
Typically, you use the Tree view to select and see multiple objects. To select multiple objects for display, use standard keyboard shortcuts, such as Ctrl,Shift, or Ctrl-A. Click an object that you select and it displays in the Schema Editor window. If you are viewing the schema using the Editable UML view, drag the objects to the Schema Editor window.
Objects selected from the tree control must have the same source node. Selecting objects from different source nodes will clear the objects previously selected from a different source node.
View Navigation
After you select the view that you want, you can navigate in the view in different ways. In tree views, you can click + beside a node to expand it. In table views, you can select an object in the associated tree view to display data in the table. In UML views, you can drag and drop objects to create new UML views and modify existing UML views.
