Map the ER diagram into a relational database schema. Describe each relation schema in parenthesized notation (not SQL) underlining the primary key. For each relation, describe any applicable integrity constraints, e.g., foreign key, referential integrity, not null, etc.
Need assistance with this question. Please show detailed steps. For each of the following (parts a through g) E-R diagrams: L. Transform the diagram to a relational schema that shows referential integrity constraints (see the following figure for an example of such a schema - underlined items are primary keys, dotted underlines refer to foreign keys, while the arrows indicate direction from foreign to primary) CUSTOMER CustomerlD CustomerName ORDER OrderlD OrderDate CustomerlD ORDER LINE OrderlD rd OrderedQuantity PRODUCT roductD ProductDescription
a) Identify the foreign keys in this schema. Explain how the entity and referential integrity rules apply to these relations. b) Produce some sample tables for these relations that observe the relational in- tegrity rules. Suggest some general constraints that would be appropriate for this schema.
