Create tables with appropriate primary and foreign keys – Database Management System
COMPUTER PROJECT
Ben & Jerry’s, located in Waterbury, Vermont, produces 190,000 pints of ice cream and frozen yogurt daily to ship to over 50,000 grocery stores in the united states and 12 other countries. Every single pint is meticulously tracked, first by being entered into an ORACLE database with the information carefully organized. Ben & Jerry uses a sophisticated data-mining tool set from a company called Business Objects to track customer tastes.
Ben & Jerry’s has hired you to track their expenses and Ms. Gifford, the MIS director, has provided you with following information:
They currently have three tables ICECREM, INGREDIENT and RECIPE tables with following attributes:
ICECREAM (Ice_cream_ID, Ice_cream_flavor, price, year_first_offered, sellling _status)
INGREDIENT( Ingredient_ID, Ingredient_name, cost)
RECIPE (Ice_cream_ID, ingredient_ID, quantity_used)
WHERE:
Ice_cream_ID is the internal Id given to an ice cream.
Ingredient_ID is the internal Id given to an ingredient selling_staus is an internal control which keeps track of ice cream sales as high, low, medium or none. If no figures are available this field has no value.
Year_first_offered is the year that ice cream flavor was first offered quantity_used is the amount of ingredient used in one pint of ice cream.
Following sample data is available:
