Not sure I understand what you are asking, but...

Native IBO datasets don't create persistent objects - the Fields[] and Params[] are arrays of tib_Column. TIB_Column fills its properties on Prepare(). It knows what kind of TIB_Column sub-class to create by reading the validation structure back from the API. Does this help?

IB_Monitor shows you the Prepare whenever it is done. It's only done when it is needed, e.g. when the statement gets invalidated by clearing and renewing the SQL property.
