This document provides instructions and requirements for 5 weekly assignments for the DBM 380 database management course. It includes assignments on recommending a database solution for a business scenario, designing a normalized database, creating and populating a database from the design, performing queries and updates on related tables in the database, and writing a cover letter for a database administrator position. The learning team assignment involves designing a database for a jewelry retailer to track customers, inventory, and orders.

DBM 380 Assignment Week 1 Database Recommendation
FOR MORE CLASSES VISIT
www.dbm380aid.com
Database Recommendation Instructions: The first and most important
database-related decisions are whether to use a database at all and, if
2. so, which database management system to use and why. Today there
are dozens of database management systems available; however, some
are better suited to specific business environments and applications
than others. For this assignment, you will analyze a business scenario,
compare the pros and cons of different database models and products,
and recommend a specific product to meet the needs of the business
scenario. You will provide the rationale for your recommendation in
terms of the suitability and business benefit. Download and read the
Brewster Business Scenario document. Write a 2-page high-level, non-
technical recommendation to present to the Brewster CEO. In your
recommendation: • Analyze the company's current system. • Describe
the problems and challenges associated with the current system. •
Explain the business benefit of moving from the current system to a
single, shared database. • Compare and contrast at least four different
database models, including the relational database model, in the
context of the company's business environment. • Suggest a specific
RDBMS solution you believe would be most Appropriate for the
company. • List the benefits the company could expect to gain from
implementing the recommended RDBMS. Cite at least two references.
Format citations using APA format. Submit your assignment.

DBM 380 Assignment Week 2 Normalized Database Design
Assignment

www.dbm380aid.com
Normalized Database Design Assignment Instructions: A relational
database must be designed and normalized before it can be created,
populated with data, and used. Database design depends on the
business scenario(s) a database architect needs to model, but all
relational database designs benefit from being normalized. Download
and follow the instructions on the Normalized Database Design
document. Note: For this assignment, you will be given a business
scenario. If you make changes during the normalization process (and
usually this is the case) you will update your ERD to reflect the changes.
Later in this course, you will be asked to implement the ERD from this
week. Submit your ERD and your normalized database design.

you created or a Microsoft® Word file containing all the SQL statements
used.

DBM 380 Assignment Week 4 Select and Update Data in
Related Tables
FOR MORE CLASSES VISIT
www.dbm380aid.com
Select and Update Data in Related Tables Instructions: Running reports
on existing data and updating data records are very common tasks in
the industry. For this assignment, you will begin with a database
containing severalpre-populated tables. Download and unzip the
Microsoft® Access® database (ZIP file) available on the Cengage's
website. (You may need to convert the database depending on the
version of Microsoft® Access® you are using. To convert the database,
follow Microsoft®'s Convert a Database to the .accdb File Format
instructions.) Open the database in Microsoft® Access® and explore the
tables it contains by following this path:
/folderYouNameWhenYouUnzip/1305627482_526407/Student/Ch07-
Intro-to-SQL/Databases/Ch07_SaleCo.mdb Note: If you have chosen
not to use Microsoft® Access® in this course, you will need to download
5. the SQL statements for MySQL, Oracle®, or SQLserver and run those
statements against your RDBMS to create a populated database.
Download the Select and Update Data in Related Tables document and
follow the instructions. Your completed assignment will consist of one
document and two screenshots placed in one document (one
screenshot showing the results of the "before" SELECT statement and a
second showing the results of the "after" SELECT statement). Submit
your assignment.

Database Administrator Instructions: Imagine that you have the
educational background, skills, and abilities to be a database
administrator. The XYZ company recently announced a vacancy for a
database administrator position, and you are very interested because
XYZ is known as a high-paying employer that is enjoyable to work for.
Because a security breach at XYZ recently made the news, XYZ's job
posting has requested all applicants to include in their cover letter a
brief description of how he or she would approach data security if
awarded the position. Research the qualifications necessary to obtain a
database administrator position. Read "Cover Letter Workshop -
6. Formatting and Organization" fromPurdue Online Writing Lab Write a
1- to 2-page cover letter briefly describing your (fictional) database
administrator-related qualifications and outlining the reasons you
believe you are the best candidate for the job. Your cover letter must
include: • A description of your education and database-related work
experience • Note: this description will likely not match your own
actual education and experience. You will need to research and include
the education and work experience appropriate to a successful
candidate for a database administrator position unless your own
personal background qualifies you for a database administrator
position • Your philosophy and approach to backing up relational data •
Your philosophy and several approaches to securing relational data and
a rationale for each approach • Address your cover letter to Mr. Ben
Smith, Director of Human Resources. Submit your cover letter.

diamonds offered are IF, VVS1, VVS2, VS1, VS2* Cut – cut scale for
diamonds offered are Excellent, Very Good, Good Color – color
scale for diamond offered are D, E, F, G, H, I, J* Order Table – The
sales team will want to prepare a sales order for existing customers and
sell only diamonds that are in inventory. The DBMS must be designed
such that customers can purchase multiple stones on one sales order.
