The idealized stack may not be completely accurate for all DIDOs, however, it provides a normative structure of what the pieces are in a DIDO Stack and in a DIDO Platform and how they are interrelated.

To accomplish this, a Database stack is presented with some idealized paths through the stack to met certain user scenarios. Then the DIDO Stack is presented as a transform of the Database Stack.
