Mis582 full course-Normalizing the Database

Subject: General Questions / General General Questions Week 2 discussion
DQ1
Normalizing the Database
Consider the following entity and its attributes. INVOICE (Number, Customer Name, Customer Number, Customer Address, Item Number, Item Price, Item Quantity, Sales Person Number, Sales Person Name, Subtotal, Tax, Total Due)
What issue does this entity have that can be solved by normalization?
What functional dependencies exist between the attributes?
How would you apply normalization to break this into more than one entity, each with a single theme?
DQ2
The Different Normal Forms
Many texts and articles will state that normalization to 3NF is sufficient.
Are there database environments that would require normalization to a higher normal form?
How about environments that do better when is there normalization to a lower normal form?
Why do you think there are so many different normal forms to choose from?
Week 3 discussion
DQ1
Data Modeling Patterns
The textbook talks about the relationships between user forms and reports and their underlying database structure. There are well-known structures used in forms and reports that translate into well-known patterns that appear regularly in an ERD (entity relationship diagram) database model.
Describe one of these data modeling patterns, along with an example of when it would be used. Do not use the examples given in the textbook.
Have you seen any of these well-known patterns in forms or reports that you have encountered at work or on the Internet? Give an example and explain what it lets you infer about the underlying structure of the database behind it.
DQ2
Entity Types and Relationships
There are many kinds of entity relationships in a database model. The relationships can be classified by the following things.
Cardinality: maximum and minimum
Degree: binary, ternary, degree 4, and so forth
Entity type: strong, weak, ID-dependent, and supertype/subtype
What are these different types of classifications? Do they overlap, or do they each tell us something unique about the entity relationship? Why is it important to classify each of these types in an ERD (entity relationship diagram) model?
Week 4 discussion
DQ1
Entity and Table Relationships
When creating relationships between tables in our database, we must consider the following entity relationships.
Non-identifying relationships between strong entities
Identifying relationships between ID-dependent entities
Mixed-entity pattern relationships
Supertype and subtype relationships
Recursive relationships
Create an example of entities in one of these relationships and describe how the entity pattern is transformed into database tables.
DQ2
Referential Integrity Actions
Representing minimum cardinality in a physical database design can be tricky depending on whether the parent-child relationship is O-O, M-O, O-M, or M-M. Give an example of one of these minimum cardinalities and how it would affect the physical database design. What are referential integrity actions, and how could you use them in your example?
Week 6 discussion
DQ1
Database Constraints
Business requirements are enforced by implementing database constraints on tables and columns. The database constraints available include the following.
PRIMARY KEY
FOREIGN KEY or REFERENTIAL INTEGRITY
NOT NULL
UNIQUE
CHECK
Give a business requirement and the constraint that could be implemented to enforce it. Explain the constraint you chose, and give the SQL to implement the constraint in the database.
What are the long-term problems when these constraints are not implemented?
DQ2Database Redesign
After your database was put into production, a design flaw was discovered! One of the relationships modeled as a 1:N relationship was really an N:M relationship. The database issue involves the following tables, with PK italicized and underlined.
VEHICLE (VIN, Make, Model, Color, LicenseTag)
DRIVERS (DriverLicenseNo, LastName, FirstName, Address, Zip, VIN)
ZIPCODE (Zipcode, City, State)
Which 1:N relationship should be an N:M relationship? How would you redesign the database to correct the issue? What else must you consider when updating the structure of your database tables?
Week 7 discussion
DQ1
Database Locking
Databases are designed to allow multiple users to have concurrent access to data. Yet this capability presents certain problems. Investigate how databases resolve multiple concurrent data management issues, including lost updates, deadlocks, and different types of lock management styles. Compare the different locking capabilities of Microsoft Access to one other database product.
Post your analysis in the thread. Do not cut and paste from the Internet. You should also respond to other posts to add additional information, clarify points, or answer questions.
DQ2
Databases for Business Intelligence
We’ve been focusing on operational databases, often called online transaction processing (OLTP) systems. These OLTP systems handle the day-to-day business of the company and are accessed by multiple users simultaneously, updating the data in short transactions.
Business intelligence systems are sometimes called online analytical processing (OLAP) systems. These OLAP systems are used to make decisions and are characterized by few users submitting long-running queries that do not update the database to analyze the historic data of the company. What are some other differences between OLTP and OLAP systems? How are data warehouses similar or different from these two database models?

Review the ERD below to understand the entities, attributes, primary keys, and relationships that you will create in your MySQL database.
STEP 1: Create a New Database
• Just like you did in the Week 1 iLab, create a new database following the naming conventions we are to use for our databases, as specified in the tutorial file Creating a Database within MySQL.pdf listed in the doc-sharing folder titled “Omnymbus Tutorial Files” in Doc-Sharing. All of our work in this iLab, will be done under this database.
STEP 2: Open MySQL via Omnymbus, Create SQL File, Drop Table
Back to Top
• To reference, learn and apply MySQL’s own dialect of the SQL language to this iLab, browse through the file M10C_KROE8352_13_SE_WC10C.pdf in the Doc Sharing folder titled My SQL Documents.
• Create a script file named LastName_Lab3.sql containing SQL statements created in Steps 3–7 below.
• But first include the following commands at the top of your script:
o SET FOREIGN_KEY_CHECKS=0;
o DROP TABLE IF EXISTS STUDENT;
o DROP TABLE IF EXISTS CAMPUS;
o DROP TABLE IF EXISTS ROOM;
o DROP TABLE IF EXISTS COURSE;
o DROP TABLE IF EXISTS INSTRUCTOR;
o DROP TABLE IF EXISTS APPROVED_INSTRUCTOR;
o DROP TABLE IF EXISTS CLASS;
o DROP TABLE IF EXISTS STUDENT_GRADE;
o SET FOREIGN_KEY_CHECKS=1;
STEP 3: Add Tables, Set Primary Keys and Foreign Keys
Back to Top
Add tables to the MySQL database.
• Add a table for each entity listed in the provided ERD diagram.
• Add a column for each attribute listed in the provided ERD diagram.
• Select primary key for each table as indicated in the provided ERD diagram.
• Identify foreign key relationship between tables as indicated in the provided ERD diagram.
• Enable referential integrity on the relationship.
• Enable cascade updates on the relationship.
STEP 4: Set Data Types for Table Fields
Back to Top
For every column in every table, update the data type as needed to enforce the domain constraints of the data.
• Dates should have a date data type.

STEP 2: Create Table, Insert Statement
Run MySQL via Omnymbus.
Modify the table creation script that will be used to create the database with the outlined attributes from the Data Dictionary.
Provide one Insert Statement that will add your contact information to the newly created table.
Save the file with a name containing Lab7_, your first initial, and your last name (e.g., Lab7_JSmith.sql).
Execute your script and ensure that the database is created.
Listen
STEP 3: Build Index PHP Page
Building Your index.php Web Page
In this step, you will complete your php script page to connect to the Lab7 database and display the MyAddressbook table on the Web page.
Complete the MySQL connection for the index.php page. Be sure to fill in appropriate host (127.0.0.1), username, password, and database information in the mysqli field.
Modify the provided php code to display each attribute of your MyAddressbook table. Note that initially, only 1 entry should be present in your table.
Save your index.php file in your public_html folder in Omnymbus file manager.
Please note that you will find your public_html folder down the path zdisk/USERID/public html
Direct your Web browser to your site url (ex. http://devry.edupe.net/~XXXX/index.php).
Note that you’ll replace XXXX with your Omnymbus login ID.
Ensure that your file executes and the database table displays on the screen.
If you have a correct connect command but you get the error message “MySQL ERROR 1045 (28000): Access denied for user” you will have to create a new password with the box “Change password in other modules?” checked.
The following image provides an example of how your index.php page should look with no entries provided in the database. Note: Feel free to add any additional formatting or images to your index.php page.
Listen
STEP 5: Build Update PHP Pages
Building Your update.php and update_data.php Pages
In this step, you will complete two php HTML pages. Your update.php page will provide a form for users to submit data to the database that will be updated. The update_data.php page will provide the actual queries in php to update the data in your database. When this process is complete, your page will redirect the user back to the index.php page.
Review the update_data.php page template.

Week 4: Task 2: Data Modeling Using Visio (50 Points)
NOTE: Visio 2010 is required for this project. Please ensure you can run Visio 2010 via Citrix or by having it installed on your computer. In case you are to run Visio 2013, there is a tutorial listed at the bottom of this document for that version of Visio, as well as a tutorial for Visio 2010.
PROJECT OVERVIEW:
Scenario and Summary
In this assignment, you will learn to create a physical database model in Visio from business requirements. To complete this assignment, you will need to be able to run Visio 2010, either through Citrix or installed on your workstation or laptop.
Deliverables
Name your Visio file as Lastname_Task2.vsd. Create and save your database model in your Visio file. When you are done, submit your document to the Week 4: Course Project Task 2 Dropbox.
STEP 1
Read the following business requirements closely to determine the entities and relationships needed to fulfill the requirements. The nouns in the paragraph will tell you the entities that will be needed. The adjectives that describe those nouns are the attributes of that entity. The verbs in the paragraph will help you determine the relationships between the entities.
ABC Company Order Inventory System
Database Requirements
The ABC company has many stores in many locations that are divided in regions. The company supplies products to these stores. For the purposes of this database you may think that it is an American company in terms of regions such as Midwest.
Each store is their customer/client. The company recognizes these stores by their store ID. They also keep track of the store name, address, and contact name.
Stores may place orders online, or by phone/fax. Each order must be uniquely identified by an order number. Each order has a date on which the order was made, a date when the order was shipped, an employee who took the order (or it could be an online order), and the mode of payment.
To make sure that the stores get their order on time, the stores are assigned to different warehouses in different regions. Currently, there is one warehouse for every region. Each warehouse is identified by its warehouse number. The company also tracks the address of the warehouse as well as a contact phone number.
There are five regions: West, Midwest, Southwest, Southeast, and Northwest. Each region is identified by its unique name and unique number.
Each warehouse holds many products for this company. A product may be found in many warehouses. The company keeps track of this inventory. At any point in time, the company must be able to find which warehouses carry this item, the quantity in stock, reorder point and whether this item is out of stock.
Each product has a unique id, a description, a price. Each product could be on many orders, and an order may have multiple products on it. The company needs to track what quantity was ordered for each product and the total price for those products.
Phone/Fax orders are processed by the employees of the company. The company keeps track of the employee’s id, first and last names, position, hire date, department they work for, their supervisor, and their salary.

Week 6: Task 3: Database Construction Using MySQL (50 Points)
NOTE: MySQL is required for this project. Please ensure you can run MySQL via Omnymbus.
PROJECT OVERVIEW:
Scenario and Summary
In this assignment, you will create and populate a MySQL database based on the ERD you created in task2. Update the ERD you submitted for task2 with the corrections required by your instructor. To help you with this task, your instructor will provide you with the data dictionary of the database. This will provide you information on every table that you must create for the ABC Company database. Every entity can be found listed in the data dictionary along with the PK/FK information as well as the data types for the attributes. These data types are MySQL data types so they can go directly in the create table statements. Using the corrected ERD and the data dictionary provided, write the necessary MySQL statements to create the ABC company database. To complete this assignment, you will need to be able to run MySQL via Omnymbus.
Deliverables
1. Corrected ERD based on the instructor feedback and data dictionary. The data dictionary titled COURSE PROJECT Week6Task3DataDictonary.xlsx can be found in the folder titled Course Project Documents. Save your file as Lastname_Task3_revisedERD.vsd.
