BIS 245 Week 3 Lab Visio ERD
http://www.homeworkmye.com/product/bis-245-week-3-lab-visio-erd |
Part A: Create a Visio ERD from Data Requirements and Business Rules Step 1: Open Visio a. Open Microsoft Office, Visio application or b. If you are using Citrix, click on Microsoft Office Applications folder to start Visio. Step 2: Identify and create the entities a. Open a new blank Database Model Diagram. b. Save the file as YourName_Lab3.vsd. c. Based on the information provided below, create the necessary entities for the Pages in Time database. If you need assistance to create the entities, refer to labs from Weeks 1 and 2. Pages in Time Pages in Time is a small bookstore carrying a variety of books. The owners have decided to computerize the books available through the store so that they can determine more easily what books are on hand and which books need to be special ordered to meet customer needs. Because customers do not always remember the name of a desired book, the owners want to be able to look for books by author or by type (genre). They also want to be able to find the publisher�s information using the system so that they can order books more easily. After visiting with the owners, you have gathered the following information on data requirements and business rules to develop a conceptual design (ERD), prepare it for conversion to an Access database, and then create the actual database. DATA REQUIREMENTS You have determined that you will need at least the following entities to resolve the relationships that exist in the data. CUSTOMERS ID Name (store data in its smallest parts) Phone Address (store data in its smallest parts) Phone Number E-mail Address Preferred Contact Method ORDERS Number Date Received Date Customer Contacted (Yes or No) BOOKS ISBN Number Title Purchase Price Year Published Fiction or Nonfiction Type (Genre) In stock AUTHOR ID Name (store data in smallest parts!) Short Biography PUBLISHER ID Name Address Phone number Contact Person Fax Number Website Step 3: 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 2 of this lab. If you have not already 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 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 in each table using the Visio column properties. Step 5: Identify the relationships a. Using the information below on the business rules for Pages in Time, create the relationships between the entities created in Step 2. b. Notice that when Many-to-Many relationships exist, you will need to create associative entities. c. For any associative entities created, enter necessary fields. You may also need to designate or create a primary key. BUSINESS RULES Business rules help determine the relationships between data that should help you design the relationships between your entities. 1. Each customer can place many orders over time, but each order is placed by only one customer. 2. Each order may include many books, and a book may be included on many orders. 3. Each book may have multiple authors, and each author may have written multiple books. 4. Each book has only one publisher, but a publisher may publish many books. Step 6: Determine and specify the data types a. Using the information below, select the data type for each attribute (field) in your diagram, and set the type in the attribute properties. As the data types and field lengths are not included in the data requirements, you should make a selection based on your knowledge of the type of data and approximation of length required. The Visio and Access data type equivalents are shown below: Access Visio Number Integer Text Text Memo LongText Date/Time DateTime Currency Currency Yes/No Binary AutoNumber Long Hyperlink No equivalent–use Text Step 7: Modify the Visio Settings to show the Data type and field size in the diagram. a. Change your Visio settings so that these appear on the actual diagram. To do this, go to the Database ribbon, Display Options. In the Display Options dialog box, select the Table tab. You will then change the data types to Show Physical. Click the OK button to apply the new setting. They data types will then appear in your diagram. Note that you may need to move the entities so that they are easily viewed as they are now larger. b. Be sure to save the final version of your file. End of Part A Part B: Create the Access Database from the ERD Preparation Open the Visio file created in Part A of this lab, you will reference this file in Part B. Step 1: Start MS Access and Open a New Blank Database. a. Create a new Blank Database; refer to the Week 2 Lab for more detailed instructions. b. Save the database as YourNameLab3. c. Note: If you are unsure how to complete any steps in this iLab, refer to the previous week’s iLabs. Step 2: Create the Tables a. 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 table d. Set the attribute properties as needed for a. Field length b. Required Step 3: Create the relationships a. Open the database relationships window. b. Based on the Visio diagram from Part A, create the relationships for your database. c. Be sure to enforce referential integrity for each relationship. Save your file. End of Part B |

BIS 245 Week 4 Lab ER Diagram
http://www.homeworkmye.com/product/bis-245-week-4-lab-er-diagram |
Page 1 of 5 A. Lab # : BSBA BIS245A-4A 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. D. Deliverables Section Deliverable Points Step 6 YourNameLab4A.vsd (Visio Diagram) E. Lab Steps Preparation 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 tab in Course Home. 2. Start Visio a. Open Microsoft Office 2010, Visio application, or Page 2 of 5 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. Page 3 of 5 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) Employees Name Position 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. If you have not already Page 4 of 5 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. BUSINESS RULES Business rules help determine the relationships between data that should help you design the relationships between your entities. 1. Each customer can book many engagements over time, but each engagement is placed by only one customer. 2. One assistant chef is assigned to each engagement. An assistant chef may work many engagements over time, but each engagement will have only one assistant chef assigned. 3. Each engagement will have many menu items. Each menu item may be served at many engagements. When a menu item is selected, the number of servings required for the event must be recorded. (Hint: Remember that an associative entity may have attributes!) 4. Each engagement must have at least one assistant chef assigned. There may be many other employees assigned to the engagement. Each employee may work many engagements. However, some employees never work engagements. 5. Only one engagement may be scheduled for any particular date and time. Page 5 of 5 Step 5: Determine and specify the data types a. Using the information below select the data type for each attribute (field) in your diagram, and set the type in the attribute properties. (Refer to the Week 2 Lab if you are not sure how to do this. Where allowed, estimate the field length needed.) As the data types and field lengths are not included in the data requirements, you should make a selection based on your knowledge of the type of data and approximation of length required. The Visio equivalents are shown below Access Visio Number Integer Text Text Memo LongText Date/Time DateTime Currency Currency Yes/No Binary AutoNumber Long Hyperlink No equivalent—use Text Step 6: Modify the Visio Settings to show the Data type and field size in the diagram. a. Change your Visio settings so that the data type and field size appear on the actual diagram. If you are unsure of the steps to do this, refer to the Week 3 Lab. b. Be sure to save the final version of your file. |

BIS 245 Week 5 Lab ER Diagram and ER Matrix
http://www.homeworkmye.com/product/bis-245-week-5-lab-er-diagram-and-er-matrix |
A. Lab # : BSBA BIS245A-5A B. Lab 5A of 7 : Database design using Visio, and based on data requirements and business rules focusing on normalizing data to third normal form. C. Lab Overview–Scenario/Summary: TCO(s): 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 the MS Visio Database Model Diagram Template. The purpose of this lab is to provide experience normalizing the database to third normal form based on limited instructions, 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. D. Deliverables Section Deliverable Points Step 1 YourName_Lab5A_ERMatrix.docx Step 3 YourNameLab5A.vsd (Visio Diagram) E. Lab Steps Preparation 1. Get the Lab5A_ERMatrix.docx document from Doc Sharing: a. Download the Lab5A_ERMatrix document file from your course Doc Sharing panel (Labs view), and Save the file to your local drive. 2. 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 tab in Course Home. 3. Start MS Visio a. Open Microsoft Office, Visio application, or b. if you are using Citrix, click on Microsoft Office Applications folder to start Visio. Page 2 of 5 Lab Step 1: Identify the entities and relationships. a. Over the past four weeks, you have created ERDs based on information provided. This week, you will complete the ERD being sure to normalize it to 3NF (third normal form). Normalization is the systematic application of rules designed to eliminate redundancy from the database. Data in previous weeks was, to some extent, normalized for you. This week, it is not. An abbreviated list of the data requirements follows. College Scheduling Data Requirements Student ID Student First Name Student Last Name Course Code Course Name Course Description Course Credit Hours Course Time Course Days Instructor ID Instructor First Name Instructor Last Name Room Number Room Capacity b. Open the Word file in the Week 5 Lab Materials, Lab5A_ERMatrix.docx c. Save the Word file as YourName_Lab5A_ERMatrix. d. An ER Matrix helps define both the entities and the relationships between the entities. Using the partially completed ER Matrix below as a guide, complete the matrix. Hint: You should end up with four entities. 1. List each entity both across and down. 2. Determine whether a relationship exists between entities and define that relationship with a verb phrase. (NOTE: The entity with the greatest number of related entities is usually the center of the ER diagram.) 3. Identify minimum (Optional or Mandatory) and maximum (only one, or one or more).Page 3 of 5 Student CourseStudent none Enrolls in; Mandatory One or more Course Is taken by: Optional One or more none e. Save the completed matrix to submit as part of your lab. Step 2: Create the initial ERD based on the matrix. a. Open a new blank Database Model Diagram in Visio. 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 Crow’s Foot notation. b. One of the issues in denormalized data is that it can result in many-to-many relationships that are not compatible with the relational database. Visio does not allow creation of a many-to-many relationship because of this incompatibility. Therefore, for any many-to-many relationships in your data, you will need to create two one-to-many relationships. See the example below:Page 4 of 5 c. Based on the information from Step 1, create the initial ERD for the College Scheduling database including the many-to-many relationships. If you need assistance to create the entities, refer to labs from Weeks 1 and 2. d. Assign the primary keys and attributes from the data requirements to the proper entities. e. Save the file as YourName_Lab5A.vsd. Step 3: Normalize the database a. While the initial ERD is accurate, if you design a database without deviating from it, you will encounter problems. For example, a course is offered many times. If you use the course code, for example BIS245, as the primary key, you will only be able to list the course once. There are three possible solutions. 1. Assign another primary key, such as an auto-number field, so that the course can be listed multiple times. However, this is not acceptable because it introduces redundancy rather than reducing it. 2. Use a composite primary key consisting of the Course Code and the Section code. If you create a unique section code (EXAMPLE: YearTerm_Section or 2010SpringA_A), then you can list the course repeatedly. Again, this introduces redundancy, and is not an acceptable solution. 3. Split the table to create two tables. To stay consistent with DeVry terminology, create a second Section table. To ensure that a course is not entered twice, you might modify the Section code to include the course: BIS245_2010SpringA_A. By consistently using this format, you should not be able to duplicate the section, and can avoid a complicated composite key. However, as the Section table will serve as an associative entity, it is acceptable to borrow the primary keys of the parent tables. b. Open the Visio file from Step 2, and add a new page. Change the page tab to read Revised. Revise the initial ERD based on the following information. 1. A Course may exist without being offered. It exists in the catalog. Courses are scheduled for a term and given a section. It is the schedule course (Section) that students enroll in, that are scheduled in rooms and assigned instructors. 2. A Student can exist without being enrolled in a course. 3. An Instructor can exist without being assigned to teach a course. 4. A Room can exist without being scheduled for a course. c. Save the file with your revised ERD.Page 5 of 5 Lab 5A Final Deliverables a. YourName_Lab5A_ERMatrix.docx (Word Document) from Lab 5A Step 1 b. YourName_Lab5A.vsd (Visio Diagram) from Lab 5A Step 3.
