The Logical View

The Logical View provides an abstract model of the system under test. You can visualize the Service and Infrastructure Components, their dependencies, inputs and outputs, and the interface patterns in this view. Use the toolbar to add resources. Use the right side of the toolbar above the drawing palette to build and modify the system under test.

In the Logical View, you work with various elements, such as, Service Components, Operations, Infrastructure Components, and Dependencies.

Service Components: Service components contain all the other elements. They can also hold other service components to represent more complex structures.
Operations: Operations define the functions of a system. You can create resources based on the information that is provided within each operation.
Infrastructure Components: Infrastructure components help you communicate with the operations that are defined in the system. These named components can be bound to physical resources. The Logical View shows only the presence of the infrastructure components, for example, a JMS server, a database, a web server, or another piece of infrastructure, but does not provide their actual details. When you create an infrastructure component, a corresponding physical resource is also created.

You can create a new component of any of these elements (service components, operations, and infrastructure components) by pressing Ctrl+N, right-clicking and by using the menu, or from the toolbar at the top of the Logical View. You can use Ctrl+F to find the resources that you create.

By using the Dependencies element, you can link operations to one another or to the infrastructure components. Outgoing dependencies are displayed in lavender and incoming dependencies, in green. Dependencies are displayed only for items in the selected diagram. To create a dependency, draw a link by using the Add a Dependency to the diagram icon in the toolbar. Alternatively, if you are configuring an infrastructure component as the transport, double-click to open the operation's properties window and edit the transport information in the Message Exchange Pattern tab.

The following additional actions are possible in the Logical View:


Action	Result
Double-click the transport icon in an operation	The transport properties dialog box is displayed: The physical transport properties dialog box, if bound The logical transport properties dialog box, if not bound
Double-click the arrows in an operation	The operation properties dialog box is displayed.
Right-click an operation	In the menu, click Open Transport. Depending on the MEP set, the following actions are possible: If the messaging pattern is set to Request/Reply, you can open logical transport, physical transport, logical stub transport, or physical stub transport. If the messaging pattern is set to Publish/Subscribe, you can open logical and physical publish transport, logical and physical subscribe transport, and logical and physical stub transport. If the messaging pattern is set to Publish, you can open logical and physical publish transport and logical and physical stub transport. If the messaging pattern is set to Subscribe, you can open logical and physical subscribe transport and logical and physical stub transport.

Toolbar and shortcuts

Use the General menu on the toolbar to add resources, such as operations, and service components, to the Logical View. Use the other toolbar menus to create logical connections to physical transports. The main toolbar for the Logical View

From the Logical View of your system under test, you can switch to a Diagram view or a Tree view.

Diagram view

You can switch to a Diagram view from the Logical View toolbar menu. When you do, you see this toolbar. The toolbar when you switch to a Diagram view

Learn more about the Diagram view tools: The following table lists the tools and describes their usage:

Table 2. Logical View toolbar menu when you switch to a Diagram view
Menu	Option
	Switches to a Tree view of the project's components.
	Draws a dependency between two operations or from an operation to an Infrastructure component.
	Configures filters to determine which dependencies are shown in the Logical View. Filters make a diagram easier to navigate in larger, more complex systems.
	Puts the cursor into selection mode, where you can select and edit elements of the model. This mode is the default cursor mode.
	Increases the zoom of the current view (zoom in). You can also do this action by pressing Ctrl+MouseWheelUp.
	Decreases the zoom of the current view (zoom out). You can also do this action by pressing Ctrl+MouseWheelDown.
	Zooms to fit an area, which is drawn with the mouse, into the screen.
	Zooms the current view to fit all the elements in the screen.
	Pans around the screen with the pan cursor.
	Automatically rearranges all elements that are contained in the Logical View to make the view clear.

Tree view

You can switch to a Tree view from the toolbar menu. When you do, you see this toolbar. The toolbar when you swtich to a Tree view
