A project is described with the project identifier, name, company where the project takes part, budget, start date, and the duration of the project. A part is presented with the part identifier, name, and price. A supplier is described by the supplier identifier, name, address, city and phone number. For each order of a product from a given supplier for a given project, we store the number of parts ordered, the price of the order, the date, and the comment. The information system SPJ includes the following tables.
