Answer the following statement true (T) or false (F)
A store displays items on shelves. An item is described by a unique item Id, Iid, its manufacturer, Man, its name, Name, the space it occupies on a shelf, Space, its cost, Cost, and its retail price, Price. A shelf is described by a unique shelf Id, Sid, and its size, Size. You can assume any reasonable domains for these attributes.
(a) Assume some items are placed on shelves. When an item is placed on a shelf a date, Remove Date, is specied at which time the item will be removed from the shelf. Give an E-R diagram that completely describes the entities and relationships of this plan. (b) In this part you are to translate the entity and relationship sets of (8a) to tables using SQL. Show all keys (foreign and otherwise). (c) We would like the database schema to enforce the restriction that the only valid shelf sizes are 100, 150, 200, and 300. Use SQL to do this. d) Show how the E-R diagram of (8a) changes if we add the restriction that no shelf is empty. (e) Sales people need not be concerned with the cost or item Ids of items. Create a view of Items that does not contain these attributes.
