Interview a database designer and ask them to give you an example of an E-R diagram showing multiple relationships between entities. Which type of E-R diagram is easier to construct when compared to a simple E-R diagram indicating simple relationships? Can a unary relationship be introduced into the E-R diagram showing multiple relationships? Is it possible to develop an associative entity between two other entities in the same diagram?
