Connection Lines 
These are the lines that connect the model elements, channeling data and events between items according to the specific type of model elements.
You use the connecting lines to indicate the direction of the flow of information or events from one model element to another.
Structure
The following table describes the types of connecting lines that can be drawn.
Line Type |
Description |
Example |
|---|---|---|
Data binding |
A connection between two UI components (or between a web service and a UI component) that channels identical data from the output port of one UI component to the input port of the other UI component. If you do not want the two UI components to share identical data, but rather use separate copies of the data, you can change the Data binding connection to a Data flow connection. Right click the connection, and select Change link to Data Flow from the context menu. |
|
Data flow |
The means by which data is channeled between a data service and connected UI components (or between two UI components whose connection was changed from Data binding to Data flow). |
|
Data mapping |
A connection between two model components, describing, for example, what data is input to an element or what fields are output from another element. This type of connection requires mapping of the data fields from the input element to the fields of the data service. When you drag out from the input port of a data service in order to create the input element, the fields are mapped automatically. |
|
Transition |
A connection between two layers, defined according to the event that triggers the transition from one layer to the other. To create a transition, select the source layer and drag the green dot at the top to the side of the target layer, releasing the mouse when the line turns into a red arrow. |
