The view model editor
54 Data Integration with Sybase Avaki Studio
Common features of view model components
This section discusses features common to the various operators, input sources, and
result elements.
Creating components
To build view models, you use the view model editor to create and manipulate objects
that represent the elements in your model. These include input sources, various opera-
tors, and result elements. When you create a new view model, Studio automatically
includes a Result. You create any other elements you require either by using the tools
in the palette or by dragging and dropping from the data catalog view. Finally, you
connect the elements together, using connection arrows, to define the flow of data
within your model.
Creating elements using the palette
The palette contains tools for creating the elements that you can use in an Avaki view
model. The palette works similarly to palettes in many graphical editor applications—
you click in the palette to select the tool you wish to use and then you click in the doc-
ument to place an instance of that object.
The tools in the palette are separated into four sections:
• The first group contains the Select tool, used to select elements in the view model
in order to edit them (see “Selecting and moving elements” on page 56) and the
Connection tool, used to connect elements together into a flow (see “Creating con-
nections between elements” on page 57).
• The second group contains the Input Source tool.
• The third, the “Operators,” group, contains basic relational algebra operations.
• The final group, “Advanced,” contains more advanced operators.
