An online company sells hundreds of office supply products on its e-Commerce store. It has asked you to design and implement a sales order processing system which will be used by users in our Operations department to process sales orders. Here is an overview of the sales order process.

Customers make purchases by placing orders.
Each customer has a customer number and profile (such as name, shipping address).
To simplify the matter, each time an order is placed, only one item is ordered.
The company maintains hundreds of products at various warehouses throughout the United States.
Each warehouse has a warehouse code, address and phone number.
The company keeps track of products carried in various warehouses and their current inventory level.

Required:
You are asked to design a relational database (Entity Relationship Diagram and normalized tables) for this company, and to complete the following five programs to process orders and to produce sales related reports for the management.

the benefits of raising bc’s minimum wage to $15 through a

series of pre-announced staged increases far outweigh the likely

costs. claims that such an increase will lead to massive job losses

in low-wage sectors of the economy are not credible.

• an increase to $15 would result in some job losses. however,

the likely impact is less than a 1 per cent reduction in the overall

provincial employment rate, and a 7.6 per cent reduction in the

employment rate for those currently making between $10.25

and $15 per hour.

• the large job loss impacts predicted by some opponents of

minimum wages misrepresent the existing economic research. in

reading and using that research, it is important to recognize that

estimates showing job loss effects of minimum wage increases

apply only to teenagers. estimated effects for young adult and

adult workers range from insignificant to non-existent.

• focusing on teenage workers plays up an inaccurate stereotype

about who earns very low wages in bc and leads to exaggerated

claims about job losses. only 26 per cent of those currently making

between $10.25 and $12 are teenagers, and only 5 per cent

of those making between $12 and $15 are teenagers.
