Develop an Entity Relationships Diagram (ERD) based on the relational schemas in the 3NF for the starting relational schema in un-normalized form presented below.
UNF:Order(OrderID, OrderDate, CustID, CustName, CustPhone, CCNum, CCExpDate, CCBank, BnkContName, BnkContPhone, CustEmail, OrderIP, SiteRefFrom, ShipStreet, ShipCity, ShipSt, ShipZip, OrderLineNum, ItemID, ItemName, ItemDesc, ItemQtyOrdered,ItemListPrice, ItemSalePrice, ItemQtyShip, ShipCharge, Tax, TotalDue)
Transform the diagram to a relational schema that shows referential integrity constraints
Question 3
Normalize table 1 to a set of Third Normal Form (3NF) relations. Your answer should show all the
three stages of normalization (1NF, 2NF and 3NF) by using the Database Design Language format
(underline all primary keys, composite keys and use an * to indicate the foreign keys). State the
component(s) that is/are removed from each Normal Form. Besides that, INF must be divided into
repeating and non-repeating group relations.
