The view model editor
58 Data Integration with Sybase Avaki Studio
Step 5 Click on the object the arrow should go to. If this object has more than one input con-
nection point, make sure that the arrow is snapped to the correct one before you click.
Step 6 If you decide you don’t want to connect the objects after all, press Escape or click a
different tool in the palette to abort the connection.
Properties dialogs
Each element in your view model can be configured by accessing its properties dialog.
You edit the properties of an Input Source using the Input Source Properties dialog,
those of an Aggregate operator using the Aggregate Properties dialog, and so on. To
open these dialogs, do either of the following:
• Double-click the element in the view model editor
• Select the element, right-click to display the context menu, and choose Edit.
Properties dialogs all have two items in common, for setting the name and description
of the element. (The only exception is the Result Properties dialog, which only has a
description field since you cannot rename the Result element.)
Element names
The names of the elements in your view model are important because you refer to ele-
ments by name in the expressions you use in configuring the model. (For more infor-
mation on expressions in Avaki Studio, see “Using expressions within Avaki Studio”
on page 66.) Element names must be unique within each model, and must meet the
same constraints as other variable names: they must start with a letter or underscore,
and must contain only letters, numbers, and underscores. Other characters (including
spaces, punctuation, accented characters, and so forth) are not allowed. If an element’s
name is invalid, or if the same name is used for more than one element, Studio dis-
plays a red border around the element in question and you will not be able to execute
or deploy the model. See “Red borders: Errors in your view model” on page 60 for
details.
