model. You might want to move elements around in order to make room for additional
operators you want to add, for example, or to neaten up the model.
Creating connections between elements
To define the flow of data within a view model, you must connect the various elements
together. The way elements are connected affects the way individual elements can be
configured. For example, a Join operator needs to have two other elements connected
to it as inputs before you can configure on which columns the join operates.
When you use the Connection tool, the order in which you select the elements you are
connecting determines the direction of data flow—data will flow from the first ele-
ment you select to the second.
To connect two elements in a view model:
Step 1 Open an Avaki view model (double-click a .avm file in the Navigator in the left pane)
or create a new one (see “Creating a project” on page 14 for instructions).
Step 2 Create at least two unconnected elements in the view model. To create an element,
click on any item in the Operators section of the palette, then click in the editor win-
dow.
Step 3 Select the Connection tool in the palette.
Step 4 Select the object the arrow should come from.
A connection line appears, attached to the output of the object you clicked and follows
the cursor as you move it. The cursor has an plug-shaped icon attached to it indicating
that you are making a connection. If the cursor isn’t over something that can be con-
nected, there is also a circle with a slash through it indicating this.
