The Data Model view
A data model stores a small quantity of data from the system under test and keeps it in memory at run time. It provides many of the features of a database while requiring a much smaller overhead.
You can create a data model at the same time that you build a data model-driven stub from recorded events. For more information, see Creating data model-driven stubs. Alternatively, you can create, modify, and delete data models by using the Data Model view.
