CIS 336 Entire Course Introduction to Database w/Lab DeVry NEW

CIS 336 Course Project DeVry

Objective

This project is designed to touch all aspects of the fundamental concepts of database design and logical data modeling covered during the class. Each student will be responsible for designing, developing, and demonstrating the functionality of a database created based on a set of business specifications that you create. At the end of the session, each student will submit a report that includes the logical and physical design of the database and demonstrates the database’s ability to deliver meaningful reports. All aspects of the project will be covered during the week or weeks prior to a deliverable, and each task deliverable in the project will be supported through the exercises and labs done in the course.

Guidelines

You will create a proposal for a commerce business of your choosing. This can be an actual or fictional business that sells products and/or services. You will determine the business rules and report requirements. Entities that must be included in your model are the following.

Customer

Product (or Service)

Project Deliverables

This task is broken down into four deliverables.

Task 0 (due at the end of Week 1) Task 1 (due at the end of Week 3) Task 2 (due at the end of Week 5) Task 3 (due at the end of Week 7)

Remember that this is a work in progress and in all likelihood, you will have to make numerous changes to your tables and schema as you go along. These changes are to be expected and are a normal part of the database design and implementation process.

Please refer to the sections below for details regarding deliverables for each task.

Task 0 (due at the end of Week 1)

The first task is to create your business narrative. Some of the questions that you should address include (but are not limited to) the following.

What is the name of your business? Who will be the users of the system (managers, employees, customers)? What product(s) and or service(s) does it sell? Be specific. Who are the customers? What is the customer base? What sales and distribution channels are used? How are payments made? Are products delivered or shipped to customers in some way? Are sales reps involved? Are they paid on commission? What type of reports are needed by the business?

Please include as much detail as possible in order to provide a foundation for Task 1. Submit your proposal as a Word document. Note that this proposal may be revised in the coming weeks as your understanding of the database modeling process grows.

Preview Week 1

“Kitoko Fashions” is online retailer store for boutique clothing products. Usually textile factories create extra items for every order and these remaining items are either discarded or recycled. We purchase these extra items from…


Develop a detailed logical model of your database based on your business scenario submitted for Task 0. Your data model will include an entity-relationship diagram (ERD) developed with Microsoft Visio or MySQL and a data dictionary (DD) developed with Microsoft Excel.

Note that your deliverables each week include any revisions to the previous task.

Submit your Task 1 deliverable as a zip file including the following.

Task 0 proposal (with any revisions or updates) Your ERD copied to a Word document that fits on a single 8 x 10 page Your DD (Excel file)

Preview Week 3

… System Users

Following are system users:

Managers, checking reports for sales, inventory etc. Employees, receiving orders and adding shipment details Customers, placing order from online website

Products

Following are major product categories:

Men’s wear o Teeso Jacketso Denim

Women’s wear o Teeso Jacketso Sleepwearo Denim

Kids & Teens o Teeso Infants….


First, make sure to make any necessary revisions to your logical model based on Task 1 feedback. Using MySQL, write the statements to develop a physical model of your database by creating the tables and constraints based on your Task 1 logical model. Be sure to use your ERD and data dictionary and create all constraints appropriately.

Once your tables are created, you will populate them with data using MySQL statements to insert records into the database. You should insert a minimum of five records into each table and more where necessary to ensure that the data in the database is sufficient to allow for each of your reports to be tested.

The result will be a script file that includes statements to

DROP all tables; CREATE all tables with constraints; INSERT data into all tables; and SELECT data from all tables to show the data in each table.

Name this file yourname_task2.txt.

Also create a Word document that shows the structure of each table and the data in each of your tables (copy and paste from MySQL). Name this file yourname_tables.docx.

Note that your deliverables each week include any revisions to a previous task.

Your final task is to use your tables for an update and for reports. There are two requirements.

1. You will demonstrate an update that includes two tables and uses a subquery. Make sure to prove that your update executed correctly by showing data in the tables before and after the update.

2. You will also develop at least four meaningful reports. One must include a join, one must use a subquery, and one must use an aggregate function. You need to describe the business requirement of the update and each report. Note that numeric PK values are not often meaningful to a person looking at the report.

You will create a script file that has each of the queries called yourname_task3.txt. You will also document the results of this task in a Word document called yourname_reports.docx to show the result of each query. For the update and each report,

o describe the update and report requirement;o show the query; ando show the result of the query.

Include a final section for Conclusions and Lessons Learned regarding the project.

Normal Forms and Entity Relationship Diagrams Introduction

In this exercise, you will analyze a de-normalized data set presented in the form of a spreadsheet. You will next construct a series of dependency diagrams, transforming the evolving data model from First Normal Form (1NF), to Second Normal Form (2NF), and finally to Third Normal Form (3NF). When the model has reached 3NF, you will construct the Entity Relationship Diagram (ERD) depicting the logical design of the database. Your ERD will use Crow’s Foot notation to denote the relationships between tables.

Sample Exercise, With Solution

Before completing your lab, please review this example problem. The diagram below is a partial depiction of a business spreadsheet for a retail store operation. The store sells books. Books have a 13-digit International Standard Book Number (ISBN), a title, a publisher, and a unit price. Invoices track sales of books. An Invoice contains one or many line items, with each line item reflecting the sale of one or more copies of a specific book. Every publisher has a company name, and a publisher code.

LAB OVERVIEW The Expanded Entity Relationship Diagram

Scenario and Summary

This lab introduces the next step in creating a data model, the Entity Relationship Diagram (ERD). You will be given a business scenario for a University Medical Center, which is a small community hospital. The business specifications will outline a number of things about the business, some of which will apply directly to the database you are being asked to model. There is a table that lists the entities (tables) that will be needed for the database and related attributes (columns) for each entity. There is also a column that lists specific information about the entity that will be helpful in determining its relationship to other entities within the model.

Be sure to include the minimum and maximum occurrences of each relationship (cardinality) and to supply a name to the relationship that will work in both directions. Make sure to use Crow’s Feet notation in your ERD.

Narrative/Case Study

The University Medical Center is a small, community hospital. A new hospital administrator has recently been hired by the Board of Directors, and directed to right-size patient care and pharmacy services and improve profitability. The hospital operates three clinical facilities: the main hospital, a mid-town clinic, and an Urgent Care location. The hospital also offers selected in-home care services. Many of the patients are repeat or regular patients who receive regular treatment for various conditions, and many utilize the hospital’s pharmacy services for prescription medications.

The pharmacy dispenses about 3,000 different prescription medications of various kinds. Every prescription is associated with one patient, and is logged by the dispensing clinic. The new administrator wants to know which drugs are most prescribed, and also which are the most profitable.

The following is some general information about the organization and its current processes.

The hospital operates three clinical facilities. A healthcare worker logs in at a facility at the start of a shift and logs out at the end.

The name, address, Social Security number and other information is recorded for every healthcare worker.

All healthcare workers have one billing rate, which is determined by their job description. Each medication dispensed by prescription is linked to both the prescription number and

the medication ID number, recording the item price and the quantity dispensed.

As a convenient and affordable means of providing hospice care, palliative care, and convalescent care to patients that need occasional/intermittent skilled nursing, but do not require hospitalization, the hospital offers limited in-home care. Recording of in-home care includes the healthcare worker ID, their departure time and return time, and also the prescription ID for any prescriptions administered by the healthcare worker in the home setting….


LAB OVERVIEW Building the Physical Model

Scenario and Summary

The lab for this week addresses taking a logical database design (data model) and transforming it into a physical model (tables, constraints, and relationships). As part of the lab, you will need to download the zip file titled CIS336Lab3Files from Doc Sharing. This zip file contains the ERD, Data Dictionary, and test data for the tables you create as you complete this exercise.

Your job will be to use the ERD Diagram found below as a guide to define the table structures and constraints using both CREATE TABLE and ALTER TABLE statements. Once this has been done, you will need to write the INSERT INTO TABLE statements to insert the data provided into the table. The data should verify that the constraints you have created are valid and define the correct referential and data integrity constraints asked for. Lastly, you will write SELECT statements to query the tables and verify the data was populated. Please use exactly the data provided, without addition, deletion, or alteration except as directed, as your results may be evaluated against expected results generated using this exact data set.

Narrative/Case Study

For this lab, you will be creating SQL statements to build a series of relational tables, using SQL CREATE statements in a script file format for the Student Database. You will then populate those tables through the use of INSERT statements with sample data.

You will need to create a script file and name it YourName_Lab3.txt containing the following code.

1. The drop table statements listed later in the specifications of this lab.2. The CREATE TABLE statements required to build the six tables.3. The INSERT statements necessary to insert all of the sample data.4. Six select statements to verify that the data is in the tables and accessible.

To help you accomplish this task successfully, you are being supplied with the ERD Diagram which follows, and the exact data to be inserted into each table, which may be found via the Doc Sharing tab on the course website.

The following guidelines are being provided to help assist you in creating your script file.

Use the names for the tables and columns as listed in the ERD. Do not change them as it will affect your grade.

Creating Constraints o Create all NOT NULL constraints as indicated in the ERD.o Create all PK constraints as indicated in the ERD.o Create all FK constraints as indicated in the ERD.

Create all of the tables and all of the constraints before populating any of the tables with data.

Because FK constraints will be in place when the insert statements are executed, you will need to consider carefully which tables must be created before others in order to ensure that FK constraints are not violated.

The COURSE table has a self-referencing FK constraint. Specifically, some courses have prerequisite courses. Consequently, the record for a course possessing a prerequisite course cannot be successfully inserted into the table unless the record for the prerequisite course has already been inserted. This may require you to reorder the insert statements to resolve FK violations when loading the table. You may reorder the data provided for this table, but do not alter it.

The data for one table intentionally contains a record containing an FK constraint that is not resolved by a record in the parent table. This orphaned record has been included as an exercise for you to find. Because this record has an unreconciled FK constraint, it cannot be successfully inserted. You will need to delete or comment out the insert statement for this one record in order to produce a script that runs without errors.

Aside from reordering the data for the COURSE table as necessary, and commenting out/deleting the ONE record whose FK dependency cannot be resolved by the data provided, you are NOT to modify, add to, or delete from the data provided. Your SQL script must produce tables containing data identical to the expected solution set, or points will be deducted.

ALL character strings must be enclosed in single quotes. This includes alpha strings and alphanumeric (remember that any formatting within a numeric string makes it alphanumeric).

If you are inserting a NULL, do not enclose the word NULL in single quotes, as this will insert the word NULL into the row. To insert a null you simply use the word NULL. …


Scenario/Summary Building the Physical Model

Lab 4 will introduce the various aspects of the SQL SELECT statement and the methods of retrieving data from the database tables. The lab will utilize a database with a set of tables that

you will create and populate using the instructions and script file found below. These tables will be used for the remaining labs in this class.

STEP 1: Create the Database and Tables

Create the database and tables (that will be used in labs 4–7) by downloading the following files.

CreateOMTables.docx (Instructions) create_OM_db.sql (Database Script)

STEP 2: Download the Week 4 Lab Instructions and Answer Sheet

Follow the instructions to complete the lab by downloading the following files.

Be sure to refer to the ERD for the database in OM_ERD.docx when creating your queries.

STEP 3: Submit Your Answer sheet

Complete the Answer Sheet to show your queries and results and submit according to the lab instructions.


Retreiving Data From Multiple Tables

Lab 5 deals with writing queries using multiple tables as covered in the reading and lecture material this week. In some cases, you will be given the option to choose the JOIN syntax to use, in other cases, you will be asked to take a specific approach. Using the incorrect process when the process is specified will result in points being taken off for that problem.

This lab will utilize the tables that were created in Lab 4. If you have not yet created these tables,you can create the database and tables (used in labs 4–7) by downloading the following files.
