A. Lab # : BSBA BIS245A-2
B. Lab 2 of 7 : Skills Development in Visio; Creation of MS Access Database
C. Lab Overview—Scenario / Summary
COs:
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.
3.     Given an existing relational database schema, evaluate and alter the database design for efficiency.
4.     Given an existing database structure demonstrating efficiency and integrity, design the physical tables.
Scenario:
You have been asked to create a conceptual database model using MS Visio Database Model Diagram Template. The purpose of this lab is to have you gain experience with the various modeling tools needed to create a conceptual model (entity relationship diagram) of a database. You will then modify the model for implementation as a MS Access database. You will create and modify one conceptual model.
You will then create a 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
1.     relying on detailed instructions, add two entities to the existing conceptual model (ERD), including attribute data types and required field lengths;
2.     create a new MS Access database file;
3.     using the model from PartA of the lab and relying on detailed instructions; create the first two tables in the database;
4.     use the experience gained in creating the first two tables to add the remaining tables;
5.     using the model from Part A of the lab and relying on detailed instructions; create the relationship between the first two tables in the database; and
6.     use the experience gained in creating the first relationship to create the remaining relationships between the tables.

E. Lab Steps
Preparation
1.     Get the Visio diagram
a.      Download Lab2_StarterFile.vsdx file from your course Lab page, 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 Lab area in the Introduction and Resources area.
b.     You will have to upload the Lab2.vsdx file to your Citrix drive, or allow Citrix access to your system. Follow the instructions for uploading files to Citrix, located in the Lab area in the Introduction and Resources area.
Lab:
|
Part A: Create a Visio ERD with an Associative Entity |
|
Step 1: Open the Lab2.vsdx file |
|
a.      Open the Lab2.vsdx file using Microsoft Office or Visio. b.     If you are using Citrix, click on Microsoft Office Applications folder to start Visio. Then use the File menu, open command to open the Lab2.vsdx file. |
|
Step 2: Add two new entities and relationships to the Visio diagram. |
|
a.      The Lab2.vsdx file should open like the following screen. Using the Save As command in the Office Button list, save the file as YourNameLab2.vsdx.   Figure 2-a b.     The existing entities may be moved by clicking and dragging to create more room. You will be adding entities to the diagram, so drag a new entity shape to the page. You will need to click more shapes and go to Softwareà Databaseà Crow’s Feet. The menu to insert a table will pop up. You will name the new entity OrderLine, and add the following attributes. 1.     OrdLineUnitPrice (required attribute) 2.     OrdLineQuantity (required attribute) 3.     OrdLineDiscount (not a required attribute) NOTE: If you need assistance to do this, refer to the instructions for the Week 1 Lab.   Figure 2-b  c.      Add a second new entity named orders with the following attributes so that your diagram matches the diagram below. 1.     OrderID (primary key) 2.     OrderDate (required) 3.     OrderRequiredDate (required) 4.     OrderShippedDate (not required) 5.     OrderShipVia (not required) 6.     OrderShipName (required) 7.     OrderShipStreet (required) 8.     OrderShipCity (required) 9.     OrderShipState (required) 10. OrderShipZip (required)    Figure 2-c d.     At this point, the OrderLine table does not have a primary key. This is an associative entity and will borrow its primary key from the two parent tables. To add to the OrderLine entity, you must first add the setforeign key attribute of ProdID. Next, drag a relationship shape to the diagram. Connect the one end to the products entity and the other end to the OrderLine entity. Name the relationship specified by. Right click the attribute ProdID in the Orderline table and select foreign key, ProdID now appears in the OrderLine table as a foreign key. If you have trouble reading the relationship, drag and move the OrderLine table as shown below.    Figure 2-d  e.      Add OrderID to the OrderLine table as an attribute. Right click and designate the attribute as a foreign key by clickiset foreign key. Drag a second relationship shape to the diagram. Connect the one end to the orders entity, and the many end to the OrderLine entity. Name the relationship included on. OrderID now appears in the OrderLine table as a foreign key. (NOTE: The page orientation in the diagram below has been changed to landscape. You will find the orientation options on the design ribbon.)   Figure 2-e  f.      Save the file. If you are not going to continue to Part B of the lab, you may close the file.  |
