Question: Consider the ER diagram shown below for a BANK database. Each bank can have multiple branches, and each branch can have multiple accounts and loans. (a) (5pts) List the strong (nonweak) entity types in the ER diagram. (b) (2pts) Is there a weak entity type? If so, give its name, its partial key, and its identifying relationship. (C) (3pts) What constraints do the partial key and the identifying relationship of the weak entity type specify in this diagram? (d) (10 pts) Suppose that every customer must have at least one account but is restricted to at most two loans at a time, and that a bank branch cannot have more than 1000 loans. Each bank can have at most 10 branches and each branch can have at most 500 accounts. List the names of all relationship types, and specify the (min, max) constraint on each participation of an entity type in a relationship type. Note: You can draw each relationship and label the (min, max) constraint on the side of each participating entity.
