Question;PrintiLab 3 of 7: Database Design Using Visio and Based on Data Requirements and Business RulesNote!Submit your assignment to the Dropbox located on the silver tab at the top of this page.(See the Syllabus section "Due Dates for Assignments & Exams" for due dates.)Remember ThisConnect to the iLab here.iLAB OVERVIEWScenario and SummaryYou 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.You will then complete an MS Access database based on the model developed in Visio, creating the necessary tables and relationships.Upon completing this lab, you will be able to:create a new Visio file for database design,using the data requirements and the business rules provided, develop a conceptual model (ERD), including attribute data types and required field lengths, andcreate a new MS Access database based on the ERD.DeliverablesPart A: Step 7: YourNameLab3.vsd (Visio Diagram)Part B: Step 3: YourNameLab3.accdb (Access Database)Page 1 of 6A. Lab #: BSBA BIS245A-3B. Lab 3 of 7: Database Design Using Visio and Based on Data Requirementsand Business RulesC. Lab Overview--Scenario/SummaryTCOs:2. Given a situation containing entities, business rules, and datarequirements, create the conceptual model of the database using adatabase modeling tool.3. Given an existing relational database schema, evaluate and alter thedatabase design for efficiency.4. Given an existing database structure demonstrating efficiency andintegrity, design the physical tables.ScenarioYou have been asked to create a database model using MS Visio Database ModelDiagram Template. The purpose of this lab is to provide experience designing,with limited instructions, a simple database based on a list of data requirementsand associated business rules.You will then complete an MS Access database based on the model developed inVisio, creating the necessary tables and relationships.Upon completing this lab, you will be able to1. create a new Visio file for database design,2. using the data requirements and the business rules provided, develop aconceptual model (ERD), including attribute data types and required fieldlengths, and3. create a new MS Access database based on the ERD.D.

If you are using Citrix for MS Visio and/or MS Access, follow the logininstructions located in the iLab tab in Course Home.LabPart A: Create a Visio ERD from Data Requirements and Business RulesStep 1: Open Visioa. Open Microsoft Office, Visio application orb. If you are using Citrix, click on Microsoft Office Applications folder to startVisio.Step 2: Identify and create the entitiesa. 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 setconsistent to those used in previous weeks so that you generate your modelin Crows Foot notation.b. Save the file as YourName_Lab3.vsd.c. Based on the information provided below, create the necessary entities forthe Pages in Time database. If you need assistance to create the entities,refer to labs from Weeks 1 and 2.Pages in TimePages in Time is a small bookstore carrying a variety of books. Theowners have decided to computerize the books available through thestore so that they can determine more easily what books are onhand and which books need to be special ordered to meet customerneeds. Because customers do not always remember the name of adesired book, the owners want to be able to look for books by authoror by type (genre). They also want to be able to find the publisher?sinformation using the system so that they can order books moreeasily.After visiting with the owners, you have gathered the followinginformation on data requirements and business rules to develop aconceptual design (ERD), prepare it for conversion to an Accessdatabase, and then create the actual database.Page 3 of 6DATA REQUIREMENTSYou have determined that you will need at least the following entitiesto resolve the relationships that exist in the data.CUSTOMERSIDName (store data in its smallest parts)PhoneAddress (store data in its smallest parts)Phone NumberE-mail AddressPreferred Contact MethodORDERSNumberDateReceived DateCustomer Contacted (Yes or No)BOOKSISBN NumberTitlePurchase PriceYear PublishedFiction or NonfictionType (Genre)In stockAUTHORIDName (store data in smallest parts!)Short BiographyPUBLISHERIDNameAddressPhone numberContact PersonFax NumberWebsiteStep 3: Identify and create attributes (fields) Page 4 of 6NOTE: Because you are creating your diagram in Visio, it will be easier tocreate the attributes prior to the relationships.a. Refer to the data requirements from Step 2 of this lab. If you have notalready created the attributes (fields) in your ERD, add them at this time.b. Be sure that you store data in its smallest parts.c. Save your file, and continue to Step 4.Step 4: Identify and designate the keysa. Detemine whether an attribute exists in each table that will satisfy therequirements of a primary key. If no appropriate field exists, create a field forthis purpose.b. Check the Primary Key property for the field in each table using the Visiocolumn properties.Step 5: Identify the relationshipsa. Using the information below on the business rules for Pages in Time, createthe relationships between the entities created in Step 2.b. Notice that when Many-to-Many relationships exist, you will need to createassociative entities. If you are not sure of the process to create relationshipsin Visio, refer to the Labs for Weeks 1 and 2. You created an associativeentity in Week 2.c. For any associative entities created, enter necessary fields. You may alsoneed to designate or create a primary key.BUSINESS RULESBusiness rules help determine the relationships between data thatshould help you design the relationships between your entities.1. Each customer can place many orders over time, but each order isplaced by only one customer.2. Each order may include many books, and a book may be includedon many orders.3. Each book may have multiple authors, and each author may havewritten multiple books.4. Each book has only one publisher, but a publisher may publishmany books.Step 6: Determine and specify the data typesa. Using the information below, select the data type for each attribute (field) inyour diagram, and set the type in the attribute properties. (Refer to the Week Page 5 of 62 Lab if you are not sure how to do this. Where allowed, estimate the fieldlength needed.)As the data types and field lengths are not included in the datarequirements, you should make a selection based on your knowledgeof the type of data and approximation of length required. The Visioand Access data type equivalents are shown below:Access VisioNumber IntegerText TextMemo LongTextDate/Time DateTimeCurrency CurrencyYes/No BinaryAutoNumber LongHyperlink No equivalent--use TextStep 7: Modify the Visio Settings to show the Data type and field size in thediagram.a. Change your Visio settings so that these appear on the actual diagram. To dothis, go to the Database ribbon, Display Options. In the Display Options dialogbox, select the Table tab. You will then change the data types to ShowPhysical. Click the OK button to apply the new setting. They data types willthen appear in your diagram. Note that you may need to move the entities sothat they are easily viewed as they are now larger.b. Be sure to save the final version of your file.End of Part APart B: Create the Access Database from the ERDPreparationOpen the Visio file created in Part A of this lab, you will reference this file in PartB.Page 6 of 6Step 1: Start MS Access and Open a New Blank Database.a. Create a new Blank Database, refer to the Week 2 Lab for more detailedinstructions.b. Save the database as YourNameLab3.c. Note: If you are unsure how to complete any steps in this iLab, refer to theprevious week's iLabs.Step 2: Create the Tablesa. Based on the Visio diagram from Part A, create the tables for your database.b. Enter the field names and the data type.c. Designate the primary keys for each tabled. Set the attribute properties as needed fora. Field lengthb. RequiredStep 3: Create the relationshipsa. Open the database relationships window.b. Based on the Visio diagram from Part A, create the relationships for yourdatabase.c. Be sure to enforce referential integrity for each relationship.Save your file.End of Part BLab 3 Final Deliverablesa. YourNameLab3.vsd (Visio Diagram)--from Lab 3 Part Ab. YourNameLab3.accdb (Access Database)--from Lab 3 Part BSubmit these files to the Week 3 iLab Dropbox.END OF LAB
