Correction For ERD

 d. For each consistency error in Figure 1, you should identify the consistency rule violated and suggest possible resolutions of the error. The ERD has generic names to help will concentrate on finding diagram errors rather than focusing on the meaning of the diagram. Answer:                Entity6 is violation of the Primary key rule. As there are 3 attributes from within Entity6 that are marked as primary key. Entity6 also violates the Identifying relationship rule, as there is no foreign key in the Entity6 table to identify the item from Entity7. Since this a weak entity type, the cardinality must be 1:1, which it is not. Entity2 is a violation of the Identifying relationship rule due to it not being a weak entity type when there is an identifying relationship.
