To transform each user view into ERD, examine the requirements and create the necessary entities, keys, and relationships. USER VIEW 1 REQUIREMENTS: For a sales rep, store the sales rep's number, name, address, and commission rate. USER VIEW 2 REQUIREMENTS: For a customer, store the customer's number, name, address, balance, and credit limit. In addition, store the number and name of the sales rep who represents this customer. A sales rep can represent many customers, but a customer must have exactly one sales rep (a customer must have a sales rep and cannot have more than one sales rep). USER VIEW 3 REQUIREMENTS: For a part, store the part's number, description, units on hand, the number of the warehouse in which the part is located, and the price. All units of a particular part are stored in the same warehouse. For example, all dishwashers of the same type are stored in the same warehouse. The company really needs to keep a history of all the prices of each part as prices are changeable. Each time a price is changed, they would like to keep track of the date it changed. USER VIEW 4 REQUIREMENTS: For an order, store the order number, the order date, the number, name, and address of the customer that placed the order, and the number of the sales rep who represents that customer. In addition, for each line item within the order, store the part number and description, the number of the part that was ordered, and the quoted price.

There is only one customer per order. On a given order, there is at most a one-line item for a given part. For example, part DR93 cannot appear in several lines within the same order. 2345 The quoted price might not match the current price in the part table, allowing the company to sell the same parts to different customers at different prices. It also allows you to change the price for a part without affecting orders that are currently on file.
