MAT 2051 Unit 2 Discussion 1
Relations and functions play important roles in computer
applications, systems management, database management, and error management. In
this discussion, you will look at relational databases and their functions and
applications.
Databases are common computer and Internet technology
applications. Online banking, shopping, iPhones, music, video, personal files,
businesses, governments, and academic institutions all use databases to store,
process, and retrieve information, including images, video, and music.
Suppose you are a database manager and oversee a large
database with the following four tables: EMPLOYEE, DEPARTMENT, SUPPLIER, and
BUYER.
Now, turn to page 168 in the text. Under Exercises, you will
see these four tables listed as 3.6.4, 3.6.5, 3.6.6, and 3.6.7.
Part 1: Table and Database Operations
Complete the odd problems from 5 through 15 on page 169.
Write out each question fully.
Write a sequence of table operations to answer the query
required for each question.
Provide the final answer to the query for each question.
Part 2: Researching the Web for Database Applications
Create two paragraphs that describe two current database
application packages. For example, you might choose Oracle and SQL Server.
Read about what these packages offer, how they are alike,
how they are different, and what applications they are best suited for.
What language is commonly used to manipulate and communicate
with database applications? Offer a few examples of statements from this
language.
Review the Discussion Participation Scoring Guide prior to
posting.
Discussion Questions (DQ)
• Initial responses to the DQ should address all components of the questions asked, include a minimum of one scholarly source, and be at least 250 words.
• Successful responses are substantive (i.e., add something new to the discussion, engage others in the discussion, well-developed idea) and include at least one scholarly source.
• One or two sentence responses, simple statements of agreement or “good post,” and responses that are off-topic will not count as substantive. Substantive responses should be at least 150 words.
• I encourage you to incorporate the readings from the week (as applicable) into your responses.
Weekly Participation
• Your initial responses to the mandatory DQ do not count toward participation and are graded separately.
• In addition to the DQ responses, you must post at least one reply to peers (or me) on three separate days, for a total of three replies.
• Participation posts do not require a scholarly source/citation (unless you cite someone else’s work).
• Part of your weekly participation includes viewing the weekly announcement and attesting to watching it in the comments. These announcements are made to ensure you understand everything that is due during the week.

APA Format and Writing Quality
• Familiarize yourself with APA format and practice using it correctly. It is used for most writing assignments for your degree. Visit the Writing Center in the Student Success Center, under the Resources tab in LoudCloud for APA paper templates, citation examples, tips, etc. Points will be deducted for poor use of APA format or absence of APA format (if required).
• Cite all sources of information! When in doubt, cite the source. Paraphrasing also requires a citation.
• I highly recommend using the APA Publication Manual, 6th edition.
Use of Direct Quotes
• I discourage overutilization of direct quotes in DQs and assignments at the Masters’ level and deduct points accordingly.
• As Masters’ level students, it is important that you be able to critically analyze and interpret information from journal articles and other resources. Simply restating someone else’s words does not demonstrate an understanding of the content or critical analysis of the content.
• It is best to paraphrase content and cite your source.
LopesWrite Policy
• For assignments that need to be submitted to LopesWrite, please be sure you have received your report and Similarity Index (SI) percentage BEFORE you do a “final submit” to me.
• Once you have received your report, please review it. This report will show you grammatical, punctuation, and spelling errors that can easily be fixed. Take the extra few minutes to review instead of getting counted off for these mistakes.
• Review your similarities. Did you forget to cite something? Did you not paraphrase well enough? Is your paper made up of someone else’s thoughts more than your own?
• Visit the Writing Center in the Student Success Center, under the Resources tab in LoudCloud for tips on improving your paper and SI score.
Late Policy
• The university’s policy on late assignments is 10% penalty PER DAY LATE. This also applies to late DQ replies.
• Please communicate with me if you anticipate having to submit an assignment late. I am happy to be flexible, with advance notice. We may be able to work out an extension based on extenuating circumstances.
• If you do not communicate with me before submitting an assignment late, the GCU late policy will be in effect.
• I do not accept assignments that are two or more weeks late unless we have worked out an extension.
• As per policy, no assignments are accepted after the last day of class. Any assignment submitted after midnight on the last day of class will not be accepted for grading.
Communication
• Communication is so very important. There are multiple ways to communicate with me:
o Questions to Instructor Forum: This is a great place to ask course content or assignment questions. If you have a question, there is a good chance one of your peers does as well. This is a public forum for the class.
o Individual Forum: This is a private forum to ask me questions or send me messages. This will be checked at least once every 24 hours.
WE’VE HAD A GOOD SUCCESS RATE ON THIS ASSIGNMENT. PLACE THIS ORDER OR A SIMILAR ORDER AND GET AN AMAZING DISCOUNT
