Consider the following ER-Diagram {SEE THE ATTCHED DOC.) Consider the ER diagram in previous slide:a)List the (non-weak) entity types in the ER diagramb)Is there a weak entity type? If so, give its name, partial key and identifying relationshipc)What constraints do the partial key and the identifying relationship of the weak entity type specify in the diagram?d)List the names of all relationship types and specify the (min,max) constraint on each participation of an entity type in a relation type. Justify your choices.e)List concisely the user requirements that led to this ER schema design. f)Suppose that every customer must hae at least one account but is restricted to at most two loans at a timem and that a bank branch cannot have more than 1000 loans. How does this show up on the (min,max) constraints? nOTES ATTACHED TOO
