Data environment
The SPJ company manages the orders of the parts from the suppliers for the projects
that run at other companies. 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.
Parts pid, name, price );
Projects( jid, name, company, budget, start, duration );
Suppliers sid, name, address, city, phone );
Orders oid, pid, jid, sid, quantity, price, date, comment );
