Data Integration with Sybase Avaki Studio 93
Deriving metadata models
Deriving metadata models
Deriving a view model from a metadata model is a way to create a new data service
with a designated output schema. When you perform this operation, Avaki Studio
checks that the view model you built generates the output schema you specified. In
other words, the results of a data service deployed from the view model will conform
to the metadata model.
Step 1 Open a project in the Navigator pane and double click a metadata model to bring it
into the editor pane.
Step 2 Right-click the table you want to derive and select Derive View Model from the sub-
menu. The View Model window displays.
Step 3 Specify the container and file name and click Finish.
The result icon shows the target schema that you selected. As you design the data ser-
vice, Avaki Studio checks that the output matches the target schema.
