The ERD is constructed in an iterative manner. The following approach is taken.

1.During requirement elicitation, customer are asked to list the "things" that the application or business process addresses. These "things" evolve into a list of input and output data objects as well as external entities that produce or consume information.

2. Taking the objects one at a time, the analyst and customer define whether or not a connection exists between the data objects and other objects.

3.Whether a connection exists, the analyst and the customer create one ore more object/relationship pairs.

4. For each object/relationship pair, cardinality and modality are explored.

1. Steps 2 through 4 are continued iteratively until all object/relationships have been defined. It is common to discover omissions as this process continues. New objects and relationships will invariably be added as the number of iterations
grows.

2. The attributes of each entity are defined.

3. An entity relationship diagram is formalized and reviewed.

4. Steps 1 through 7 are repeated until data modeling is complete.
