CIS 515 WEEK 3 ASSIGNMENT 3 UNIVERSITY DATABASE

Assignment 3: University Database
Due Week 3 and worth 90 points

A prestigious university has recently implemented a consolidation strategy that will require it to centralize their student records. In order to move forward, the local university will need to develop a data model that will retain student records and perform various data extract transform and load (ETL) processes. Imagine that you have been hired as a database consultant to assist in the development of a data design strategy for the student records.

You met with various university subject matter experts and have determined the following after performing various business analysis processes:

Faculty groups are divided by core competencies that the university offers. For example, there are groups such as the Art Faculty, Computer Technology Faculty, Language Faculty, and Science Faculty. Each faculty member has an assigned Dean and is designated to teach at one particular campus and school. They are able to teach as many courses as required.
Courses are categorized by course code and title. Certain courses have prerequisites and the university has asked for this to be cataloged as well.
There are various schools within each campus. For example, the Los Angeles campus holds the following schools: School of Science, School of Law, and School of Computer Technology. Additionally, each school offers different professional study programs such as Forensic Computer Science, Marine Biology, Business Management, and Civil Engineering to name a few.
The study path for students requires that they be enrolled in a specific professional study program. The professional study program requires the students to complete a specific set of core courses. The university also requires that an online grade book be available. The online grade book should show grades awarded to students for specific courses and the term they completed the course.
The university identifies each student by his or her name, date of birth, social, and professional study program.

Using these findings, write a three to four (3-4) page paper in which you:

Analyze the university’s requirements and provide a proposal to organize all the required data elements. The proposal should include the following:
Provide an Entity Relationship Model (ERM) that will describe the data structure that will store all data elements. Note: The graphically depicted solution is not included in the required page length.
Describe any assumptions or limitations for each relationship. For example, professors are able to teach more than one course or students can only be enrolled in one program.
Create the primary key and foreign keys using a UML Class diagram for each table.
Suggest at least four (4) types of business intelligence reports that could help the university in course management, student enrollment, or historical tracking. Support your answer by providing specific business functions that these reports could assist executives of the university.
As an alternative for development of the database, you are considering outsourcing the functions above. Research the Internet and other media sources for vendors who develop registrar and school management database systems.
Suggest three (3) vendors that developed and are employing efficient registrar and school management database systems and support your reasons to choose from one (1) of these three (3) vendors.
Compare and contrast the key aspects that each system offers. Examples of system aspects include but not limited to cloud based, pricing model, open source, etc.
Use at least three (3) quality resources in this assignment. Note: Wikipedia and similar Websites do not qualify as quality resources.

Your assignment must follow these formatting requirements:

Be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must follow APA or school-specific format. Check with your professor for any additional instructions.
Include a cover page containing the title of the assignment, the student’s name, the professor’s name, the course title, and the date. The cover page and the reference page are not included in the required assignment page length.
Include charts or diagrams created in Excel, Visio, MS Project, or one of their equivalents such as Open Project, Dia, and OpenOffice. The completed diagrams / charts must be imported into the Word document before the paper is submitted.

The specific course learning outcomes associated with this assignment are:

Describe the role of databases and database management systems in managing organizational data and information.
Recognize the historical development of database management systems and logical data models.
Design and implement a database solution to solve a proposed business problem.
Use technology and information resources to research issues in the strategic implications and management of database systems.
Write clearly and concisely about topics related to the strategic planning for database systems using proper writing mechanics and technical style

CIS 515 WEEK 6 ASSIGNMENT 5 TOUR OPERATOR AGENCY DATABASE

Assignment 5: Tour Operator Agency Database

The Strayer Oracle Server may be used to test and compile the SQL Queries developed for this assignment. Your instructor will provide you with login credentials to a Strayer University maintained Oracle server.

A multinational tour operator agency has gained updated business growth in the North American market through the use of social media. Its operation has expanded by 50% within six months and the agency requires an enhanced data management strategy to sustain their business operations. Their existing data repository for its reservation processing system is limited in business intelligence and reporting functionalities. The tour operator seeks a database management specialist to assist them in leveraging their data sources to enable them to forecast and project tour sales appropriately.

Imagine that you have been hired to fulfill their need of enhancing the data repository for their current reservation processing system. Upon reviewing the system, you find that the data structure holds redundant data and that this structure lacks normalization. The database has the following characteristics:
•A table that stores all the salespersons. The table holds their employee id, first name, last name and “Tours sold” field. The “Tours sold” field is updated manually.
•A table that stores tour customer data and tours sold. The table holds customer name, address, city, state, zip code, tour(s) selected, number of persons in tour, and total amount paid. The current structure will show the customer more than once, if the customer books multiple tours.
•A tour table that is used as a tour rate sheet which holds the tours offered and the cost per person. Tour rates vary every three (3) months depending on the tourist season.

Write a three to four (3-4) page paper in which you propose an enhanced database management strategy. Your proposal should include the following:
1.Design a data model that will conform to the following criteria:
a.Propose an efficient data structure that may hold the tour operator’s data using a normalization process. Describe each step of the process that will enable you to have a 2nd Normal Form data structure.
b.Create naming conventions for each entity and attributes.
c.Conclude your data model design with an Entity Relationship Model (ERM) that will visually represent the relationships between the tables. You may make use of graphical tools in Microsoft Word or Visio, or an open source alternative such as Dia. Note: The graphically depicted solution is not included in the required page length.
2.Construct a query that can be used on a report for determining how many days the customer’s invoice will require payment if total amount due is within 45 days. Provide a copy of your working code as part of the paper.
3.Using the salesperson table described in the summary above, complete the following:
a.Construct a trigger that will increase the field that holds the total number of tours sold per salesperson by an increment of one (1).
b.Create a query that can produce results that show the quantity of customers each salesperson has sold tours to.
4.Support the reasoning behind using stored procedures within the database as an optimization process for the database transactions.

Your assignment must follow these formatting requirements:
•Be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must follow APA or school-specific format. Check with your professor for any additional instructions.
•Include a cover page containing the title of the assignment, the student’s name, the professor’s name, the course title, and the date. The cover page and the reference page are not included in the required assignment page length.
•Include charts or diagrams created in Excel, Visio, MS Project, or one of their equivalents such as Open Project, Dia, and Open Office. The completed diagrams / charts must be imported into the Word document before the paper is submitted
