ASSIGNMENT: DATABASE SYSTEMS PROJECT
This project is about a company called the Merchandise Distribution Company or MDC. MDC buys merchandise from suppliers both American and foreign and sells the merchandise to stores. When the merchandise arrives MDC first stores the merchandise in warehouses and then the sales representatives sell the merchandise to the different stores. The following tables are used in this project.
The "ST" or STORE table has 6 columns and each row describes one of the stores to whom we sell merchandise. Each store is given a unique store number (STORENO) which is the PK of the table. NAME is the next column and is the name of the store. CITY and STATE are the next two columns and tells us the location of the store. MGR_NAME is the name of the manager of the store. COUNTRY is the country where the store is located.
The "I" or ITEM table has 6 columns. The first column is ITEMNO which is a unique number assigned to each item so we can identify it easily. It is the PK of the table. NAME is the next column and is the name of the item. COLOR is the color of the item. WEIGHT is the weight of the item. PRICE is the current price of the item that we sell to stores. DESC is the last column and it is a description of the item.
