What is the link between a data model and a DFD?
What will be an ideal response?
Data elements included in data flows also appear in the data model, and vice versa. You must include in the data model any raw data captured and retained in a data store, and a data model can include only data that have been captured or that have been computed from captured data. Because a data model is a general business picture of data, both manual and automated data stores will be included. Each data store in a process model must relate to business objects represented in the data model. You can use an automated repository to verify these linkages.
