. It differs from the flowchart as it shows the data flow instead of the control flow of the program. The highest level of abstraction for the data model is called the Entity Relationship Diagram (ERD). Provide a name and press OK. 7. For example, a data model might include an entity class called "Person", representing all the people who interact with an organization. Storage technology can change without affecting either the logical or the conceptual model. These notations are often represented in graphical form.[7]. It is a graphical language for visualizing, specifying, constructing, and documenting the artifacts of a software-intensive system. It is a graphical representation of data requirements for a database.
