= Decouple an Application from a Confederation of Applications =

----

In this example you have a number of applications that are linked by a common database.  The custom maps will need maintenance whenever any of the applications change.  Even new updates to commercial software can break a link.  You wish to be able to modify the applications without breaking the information flow to the database.

'''Figure 1 - Applications Mapped to a Common Database'''

In order to isolate, say, Application A so that you can update it independently, you will need to create a map between it and the common database.  Use ISO 15926-4 instead of making a custom map.
