- Below is “Book Order,” the only table in library management system’s database. The design of “Book Order” as you may tell is in the zero normal formal form, you as the database designer want to convert the design into the third normal form.

ORDERLINE(Order#, Part#., Amount-Ordered) PART(Part#., Desc, Stock, Item-Class, Unit -Price) Design a physical ER for the above scenario. With respect to this relative schema, write SQL statements for the subsequent queries: List the name of the client United Nations agency has placed Order 123 (i.e. Order: = 123). List the names of shoppers United Nations agency in Cardiff and have ordered half 456 (i.e. Part. 456). List the order numbers (Order) for orders that contain a minimum of three elements and also the quantity ordered are minimum of ten. List the outline (Desc), of these elements that the typical quantity ordered is bigger than the number ordered for half .6 (Part. = 456) so as 123.(Order. .123).What is the difference between disjoint constraints and overlapping constraints, and how are they used?
