Discuss why you would want to validate a conceptual data model and describe two approaches to validating a conceptual model.
What will be an ideal response?
We validate a conceptual data model to check the model to ensure that the model supports the
transactions required by this view. Using the model, we attempt to perform the operations
manually. If we can resolve all transactions in this way, we have checked that the conceptual
data model supports the required transactions. However, if we are unable to perform a
transaction manually there must be a problem with the data model, which must be resolved. In
this case, it is likely that we have omitted an entity, a relationship, or an attribute from the data
model.
Two possible approaches to ensuring that the local conceptual data model supports the
required transactions are:
(1) describing the transactions;
(2) using transaction pathways.
