In a development platform, a classifier for a given application defines a data
model of an application model as a pattern (an object model) from a finite number
of patterns (object models) that represent the possible permutations of data models.
In addition, the development platform has a finite number of service objects that
perform various functions/services on the object model from which the application
model adopts one or more service objects. The object models and the service objects
are generic to the development platform and usually a set of finite number of object
models and a set of finite number of service objects can interface the application
model with the various third party resources and tools.
