Ganesh,

Exactly what do you mean by an LDM when you refer to it as a Logical Data Model of the operational databases? An LDM is not about operational databases or even databases for that matter. The LDM should be a model of the client organization and eventually guide you to building an appropriate database. In LDM work, the data should be the clay used by the modeler and not be the subject of the exercise.
