Conceptual data modeling is the process of capturing the satellite view of the business requirements.
•
The end result of the conceptual data modeling phase is a conceptual data model (CDM) that shows the key
concepts needed for a particular application development effort.
A concept is a key term that is both basic and critical to your audience.
•
The main reason for conceptual data modeling is to get the “big picture” and understand the scope and needs
of the project. Having a common level of understanding leads to refining scope and direction, raising
key issues early in the process, and defining the most important terms.
•
There are five steps to conceptual data modeling: ask the five strategic questions, identify and define the con-
cepts, capture the relationships, determine the most useful form, and review and confirm.
Be creative on the form you choose for the conceptual data model. Think of your users and validators.
