ERD for BANK database

Consider the ER diagram shown in Figure 1 for part of a BANK database.

Each bank can have multiple branches, and each branch can have multiple accounts and loans.

1. List the (non-weak) entity types in the ER diagram.
2. Is there a weak entity type? If so, give its name, partial key, and identifying relationship.
3. List the names of all relationship types, and specify the (min, max) constraint on each participation of an entity type in a relationship type.
