Database design based on data requirements

Database design based on data requirements and business rules focusing on interpreting business rules to determine relationships.

C. Lab Overview—Scenario/Summary


1. Given a business situation in which managers require information from a database, determine, analyze and classify that information so that reports can be designed to meet the requirements.

2. Given a situation containing entities, business rules, and data requirements, create the conceptual model of the database using a database modeling tool.


You have been asked to create a database model using MS Visio Database

Model Diagram Template. The purpose of this iLab is to provide experience designing, with limited instructions, a simple database based on a list of data requirements and associated business rules.

Upon completing this iLab, you will be able to

1. create a new Visio file for database design; and

2. using the data requirements and the business rules provided, develop a conceptual model (ERD), including attribute data types and

required field lengths.

E. Lab Steps


1. Using Citrix for MS Visio and/or MS Access

a. If you are using the Citrix remote lab, follow the login instructions located in the iLab area in Course Home.

2. Start Visio

a. Open Microsoft Office 2013, Visio application, or

b. if you are using Citrix, click on Microsoft Office 2013

Applications folder to start Visio.


Step 1: Identify and create the entities

a. Open a new blank Database Model Diagram. If you need assistance with this, refer to the Week 1 Lab Instructions. Be sure that all options are set consistent to those used in previous weeks so that you generate your model in Crow’s

Foot notation.

b. Save the file as YourName_Lab4A.vsdx.

c. Based on the information provided below, create the necessary entities for the Catering by Caren database. If you need assistance to create the entities, refer to the iLabs from Weeks 1 and 2.

Catering by Caren

Catering by Caren is an upscale catering company focusing on full, four- course gourmet dinners for groups from two to 40. Owner/chef James Caren is wonderful in the kitchen, but has become overwhelmed with the business side of running his rapidly growing operation. You have been hired as his business manager, and you’ve decided to computerize information on the engagements.

Chef Caren is excited about this project and has provided you with the following information. He doesn’t know databases nearly as well as he knows haute cuisine, so the data requirements are not well-organized, nor is data in its smallest parts. He has noted whether the menu items are appetizers, salads, main courses, or desserts. He has also provided a list of the information he keeps on each customer and each booking.

By talking with Chef Caren, you feel you have enough information on the company’s business rules to understand the relationships between the data. Chef Caren is particularly concerned that you capture the exact requirements for the menu for each engagement. For instance, if 20 people are to be served, he wants to know how many want the vegetarian main course, the Kosher meals, and so forth.

At this point, you are going to use the following information to put together an entity relationship diagram that you will then use with Chef Caren to verify that you have accurately captured the requirements.

Customers Name Phone Address E-mail Address Approved for credit or not Engagements Date Time Location Menu Number of Attendees Special Diet Plates Assistant Chef Assigned Employees Assigned Payment Method (AmEx, Visa, MasterCard, Check, Cash, Bill) Deposit Amount Deposit Paid Date Total Charges Balance Paid Date Menu Items Item Name Description Classification (Appetizer, Salad, Main Course, Dessert) Special Diet Item (Kosher, Vegetarian)
