1. Consider the ER diagram shown below for part of a BANK database. Each bank can have multiple branches, and each branch can have multiple accounts and loans BANK BRANCHES BANK-BRANCH Addr Addr ACCTS LOANS LoanNo ACCOUNT A-C L-C CUSTOMER Addr a. List the strong entity types in the ER diagram. b. Is there a weak entity type? If so, give its name, partial key, and identifying c. What constraints do the partial key and the identifying relationship of the weak d. List the names of all relationship types, and specify the (min, max) constraints on e. List concisely the user requirements that led to this ER diagranm relationship. entity type specify in the above diagram? each participation of an entity type in a relationship type. Justify your choices. f. 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 1,000 loans. How does this show up on the (min, max) constraints
