AndroMDA – modern enterprise applications are built
using several components connected to one another, each
providing a specific functionality. components that perform
similar functions are generally grouped into layers. these
layers are further organized as a stack where components
in a higher layer use the services of components in a lower
layer. a component in a given layer will generally use the
functionality of other components in its own layer or the
layers below it.
