B. Lab 4A of 7: Database design based on data requirements and business rules focusing on interpreting business rules to determine relationships.

C. Lab Overview –Scenario/Summary

TCO(s):

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.

Scenario:

You have been asked to create a database model using MS Visio Database Model Diagram Template. The purpose of this lab 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 lab, 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.

b. if you are using Citrix, click on Microsoft Office 2010 Applications folder to start Visio.

Lab:

Step 1: Identify and create the entities

a. Open a new blank Database Model Diagram. If you need assitance 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 Crows Foot notation.

b. Save the file as YourName_Lab4A.vsd.

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 Labs 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 forty. 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.

NOTE: You may find it helpful to consider the business rules in Step 4 in creating your entities.

Step 2: Identify and create attributes (fields)

NOTE: Because you are creating your diagram in Visio, it will be easier to create the attributes prior to the relationships.

a. Refer to the data requirements from Step 1 of this lab. Ifyouhavenotalready

created the attributes (fields) in your ERD, add them at this time.

b. Save your file and continue to Step 3.

Step 3: Identify and designate the keys

a. Detemine whether an attribute exists in each table that will satisfy the requirements of a primary key. If no appropriate field exists, create a field for this purpose.

b. Check the Primary Key property for the field(s) in each table using the Visio column properties.

Step 4: Identify the relationships

a. Using the information below on the business rules for Catering by Caren, create the relationships between the entities created in Steps 1 and 2.

b. Notice that, where Many-to-Many relationships exist, you will need to create associative entities. If you are not sure of the process to create relationships in Visio, refer to the Labs for Weeks 1 and 2. You created an associative entity in Week 2.

c. For any associative entities created, enter necessary fields. You may also need to designate or create a primary key. NOTE: If the relationship is mandatory (must have at least one…) you will go to the relationship Miscellaneous property and change it from Zero to Many to One to Many.

Important information for writing discussion questions and participation

Welcome to class

Hello class and welcome to the class and I will be your instructor for this course. This is a -week course and requires alot of time commitment, organization, and a high level of dedication. Please use the class syllabus to guide you through all the assignments required for the course. I have also attached the classroom policies to this announcement to know your expectations for this course. Please review this document carefully and ask me any questions if you do. You could email me at any time or send me a message via the “message” icon in halo if you need to contact me. I check my email regularly, so you should get a response within 24 hours. If you have not heard from me within 24 hours and need to contact me urgently, please send a follow up text to

I strongly encourage that you do not wait until the very last minute to complete your assignments. Your assignments in weeks 4 and 5 require early planning as you would need to present a teaching plan and interview a community health provider. I advise you look at the requirements for these assignments at the beginning of the course and plan accordingly. I have posted the YouTube link that explains all the class assignments in detail. It is required that you watch this 32-minute video as the assignments from week 3 through 5 require that you follow the instructions to the letter to succeed. Failure to complete these assignments according to instructions might lead to a zero. After watching the video, please schedule a one-on-one with me to discuss your topic for your project by the second week of class. Use this link to schedule a 15-minute session. Please, call me at the time of your appointment on my number. Please note that I will NOT call you.

Please, be advised I do NOT accept any assignments by email. If you are having technical issues with uploading an assignment, contact the technical department and inform me of the issue. If you have any issues that would prevent you from getting your assignments to me by the deadline, please inform me to request a possible extension. Note that working fulltime or overtime is no excuse for late assignments. There is a 5%-point deduction for every day your assignment is late. This only applies to approved extensions. Late assignments will not be accepted.

If you think you would be needing accommodations due to any reasons, please contact the appropriate department to request accommodations.

Plagiarism is highly prohibited. Please ensure you are citing your sources correctly using APA 7th edition. All assignments including discussion posts should be formatted in APA with the appropriate spacing, font, margin, and indents. Any papers not well formatted would be returned back to you, hence, I advise you review APA formatting style. I have attached a sample paper in APA format and will also post sample discussion responses in subsequent announcements.

Your initial discussion post should be a minimum of 200 words and response posts should be a minimum of 150 words. Be advised that I grade based on quality and not necessarily the number of words you post. A minimum of TWO references should be used for your initial post. For your response post, you do not need references as personal experiences would count as response posts. If you however cite anything from the literature for your response post, it is required that you cite your reference. You should include a minimum of THREE references for papers in this course. Please note that references should be no more than 5 years old except recommended as a resource for the class. Furthermore, for each discussion board question, you need ONE initial substantive response and TWO substantive responses to either your classmates or your instructor for a total of THREE responses. There are TWO discussion questions each week, hence, you need a total minimum of SIX discussion posts for each week. I usually post a discussion question each week. You could also respond to these as it would count towards your required SIX discussion posts for the week.

I understand this is a lot of information to cover in 5 weeks, however, the Bible says in Philippians 4:13 that we can do all things through Christ that strengthens us. Even in times like this, we are encouraged by God’s word that we have that ability in us to succeed with His strength. I pray that each and every one of you receives strength for this course and life generally as we navigate through this pandemic that is shaking our world today. Relax and enjoy the course!
