which you address the following:
Accurately definethe terms "database system" and "relational database
architecture".
In your Learning Team next week, you will have a defined application
for a database that you will construct together, but this week, think
about what you personally could use a database for in your personal
life. Choose a subject from your work/home/hobby that requires the
keeping of multiple records; e.g., music collections, sales records,
inventory. You will not be creating this database in this course, but will
use the idea this week to practice the skills required to take an idea into
the planning of a database.

Completelydefine the objectives for the database application that would
provide a solution for your record keeping requirements.
List the data specifications (must include a minimum of three entities
with attributes).
List at least two constraints and assumptions for your solution.
Describe at least two basic database functions that a spreadsheet cannot
perform.

DBM 380 Assignment Week 1 Database Recommendation
www.dbm380edu.com
Database Recommendation
Instructions:
The first and most important database-related decisions are whether to
use a database at all and, if 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.dbm380edu.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.

Start working on your Learning Team Database and Presentation
outlined above with delivery in Week Four. Begin by analyzing the
requirements provided. Identify the tables, fields, field attributes, and
table relationships required.
Build a 1-page Entity Relationship Diagram that models the required
tables and relationships using Microsoft® Visio®, Lucidchart, or
another software tool of your choice. The table design and relationships
must support the following functionality:
– Each customer is assigned a unique customer number but
may have multiple locations to ship to. The sales team needs to be able
to select the customer and the location for preparing sales orders.
– The sales team will want to query the inventory to
find diamonds that meet the following specifications of their customers:
– what SD has paid for the stone
– what SD will sell the stone for
– weight
– clarity scale for diamonds offered are IF, VVS1, VVS2,
VS1, VS2*
– cut scale for diamonds offered are Excellent, Very Good, Good
– color scale for diamond offered are D, E, F, G, H, I, J*
– 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.
*Diamond Scale Reference*
- Internally Flawless
– Very, very slightly included (pavilion)
– Very, very slightly included (crown)
– Very slightly included (under 10X magnification)
– Very slightly included (to the naked eye)

– Colorless – color between D, E, and F diamonds can be
detected only by a gemologist in side by side comparisons, and rarely by
the untrained eye
– Near Colorless – diamonds color rated by a gemologist
