| ### The view facility

Display different views of your application, such as

- All the jobs and jobsteps that process a particular file
- All the jobs that execute a particular program
- All the jobs that make up an AU Inventory Group
- All the job steps in a given job
- The statements in a job step

From these views, you can see where the various components of the application are used and shared. You can navigate from one view of the application to another to identify all impacts of date changes. Pick an object and see where the impacts of modifying that object will be. For example, pick a dataset and find all the jobs that use that dataset, all the modules that use it, all the DD names used for it. Pick an object and find where its definition is and what inventory groups it is in. Determine where particular input is created and where particular output is used. For any object type, you can find all of the impacts on other objects. All with a click of a mouse.

The structure window shows you graphically how an application is structured in a top-down tree view. See graphically what jobs are in an application, what job steps are in the job, what modules are executed in each step, what datasets are used where.

to get a look at Application Understanding.

All of this understanding of your applications can be invaluable in identifying date impacts, validating (or re-working) your work units and team assignments, seeing where bridges and date interfaces will be needed. In addition, the inventory groups help you track your progress.
