James River Jewelry Project – Data Model

By

James River Jewelry

James River Jewelry wants to expand its database applications beyond the recording of purchases and purchase awards The company still wants to maintain data on customers, purchases, and awards, but it wants to include other data as well. Specifically, James River Jewelry wants to record artists and styles and keep track of which customers are interested in which artists and styles.

James River Jewelry sells most of its jewelry on consignment, so the company does not pay the artist of a piece of jewelry until it is sold. Typically, the company pays artists 60 percent of the sales price, but the terms are negotiated separately for each item. For some items, the artists earn a larger percentage and for others, they earn less. Artists and James River Jewelry personnel agree on the initial sales price at the time the item is brought to the shop. When an item has been in the shop for some time, James River Jewelry may reduce the price; sometimes it renegotiates the sales percentage.

  1. Draw an E-R data model for the James River Jewelry database ( A shell schema has been included for your use). Use the IE Crow's Foot E-R model for your E-R diagrams. Justify the decisions you make regarding minimum and maximum cardinality. 
  2. Extend and modify the E-R data model to show James River Jewelry's award program. Use the IE Crow's Foot E-R model for your E-R diagrams. Create appropriate identifiers and attributes for each entity. Justify the decisions you make regarding minimum and maximum cardinality. 
  3. Extend and modify the E-R data model in part B to meet James River Jewelry's new requirements. Use the IE Crow's Foot E-R model for your E-R diagrams. Create appropriate identifiers and attributes for each entity. Justify the decisions you make regarding minimum and maximum cardinality. 
  4. Describe how you would go about validating the data model in part C.

Washing Machine Controller GUI in Java programming - Flinders University

By
Washing Machine TaskWrite a Java program that simulates a washing machine. The graphical user interface consists of two parts: the control panel for setting up washing conditions and the drawing panel for simulating the turbo movement when the machine starts. Note: the example GUI is to illustrate the key interface components rather than suggesting this is the only interface that everyone should stick to. You are encouraged to come up with your own design. Level 1: Appearance and layout Think about appropriate fonts and colours for the labels and the display. Also spend some time on background colours, borders, and the shape of buttons. Work out a layout that resembles a washing machine control panel. Washing machines usually have different interfaces, but they share some common components. You are also encouraged to design a novel interface that you could possibly justify. You may use any number of panels and any layout managers. Level 2: Event handling The toggle “ON/OFF” button turn
