DATABASE APPLICATION

NAM’s executive management based on the result of the cost-benefit analysis recommendation to develop the inventory and sales database management system in house. Currently it has a sample orders spreadsheet that looks like this:

There are other related spreadsheets being used. Some examples are customer information spreadsheet, sale representative spreadsheet, product information spreadsheet. NAM had to create several spreadsheets because of its inherent size limitations. Increase in their sales and growth continues and they have to split its order data into multiple spreadsheets to fit in new information.

NAM’s employees have difficulty accessing related data. For example, if the sales representative wants to see a customer’s address and the product’s standard price, the employee must open and search other spreadsheets that contain this data.

DATA:

Having decided to replace its spreadsheet to a database, management has determined that Premiere Products must maintain the following information about its sales reps, customers, and parts inventory:

The sales rep number, last name, first name, address, total commission, and commission rate for each sales rep. The customer number, name, address, current balance, and credit limit for each customer, as well as the number of sales rep who represents the customer. The part number, description, number of units on hand, item class, number of warehouse where the item is stored, and unit price for each part in inventory. NAM must also store information about its orders. The figure below shows a sample order:

The sample order has three components:

Heading (top) of the order contains the order number and date; the customer’s number, name, and address; and the sales rep’s number and name. The body of the order contains one or more order lines. Each order line contains a part number, a part description, the number of units of the part ordered, and the quoted price for the part. Each order line also contains a total (line total), which is a result of multiplying the number ordered by the quoted price. The footing of the order contains the order total.

NAM must also store the following items for each customer’s order:

For each order, the company must store the order number, the date the order was placed, and the number of the customer that placed the order. The customer’s name and address and the number of the sales rep who represented the customer are stored with the customer information. The name of the sales repo is stored with the sales rep information. For each order line, the company must store the order number, the part number, the number of units ordered, and the quoted price. Remember that the part description is stored with the information about parts. The results of the multiplying the number of units ordered by the quote price is not stored because the computer can calculate it when necessary. The overall total is also not stored. Instead, the computer calculates the total whenever an order is printed or displayed on the screen.

RELATIONSHIPS:

NAM is also interested in the relationships between the categories. For example, an employee wants to be able to associate orders with the customers that ordered them, the sales repo who coordinated the orders and the products that customer requested.

Here are the relationships they have identified so far:

A sales rep can have many customers but a customer can only have one sales rep. A customer can have several orders. An order can have several products and a product can be in different orders.

Currently NAM has the following spreadsheets:
