DBM 380 Week 1 Database Recommendation
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 Brewton Business Scenario document.
Write a 2-page high-level, non-technical recommendation to present to the Brewton 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 Week 2 Normalized Database Design Assignment
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.
DBM 380 Week 3 Create and Populate a Database
Resources: “SQL CREATE DATABASE Statement,” “SQL CREATE TABLE Statement,” “SQL PRIMARY KEY Constraint,” “SQL FOREIGN KEY Constraint,” and “SQL INSERT INTO Statement”
For this assignment, you will create the database you designed in Week 2.
Download the Create a Database document and follow the instructions.
Submit the database containing all the tables you created or a Microsoft® Word file containing all the SQL statements used.
DBM 380 Week 4 Select and Update Data in Related Tables
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 several pre-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 Formatinstructions.)
Open the database in Microsoft® Access® and explore the tables it contains by following this path:
Note: If you have chosen not to use Microsoft® Access® in this course, you will need to download 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.
DBM 380 Week 5 Database Administrator
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 – Formatting and Organization” from Purdue 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.
