Covered in Chapter 6, you know that in a database design, a fan trap happens when you have one entity in two 1:M relationships to other entities. This results in an association with the other entities that is not expressed in the data model. Suppose a data modeler has three entities: bank branch, departments, and customers. The initial data model depicts the department and employees each sharing a 1:M relationship with the district entity. The bank branch has many departments and employs many employees. In its current state, the model represents a fan trap. Draw a general diagram of the existing relationship followed by a description of the problem presented by the fan trap. Conclude by presenting a diagram that shows the resolution to the fan trap. Briefly explain the diagram that portrays the resolution.
