Grading:

Overall Course Grading

  • The exam will count 25% of your total grade. You will know in advance the standards for each assignment. My goal is to give you prompt, clear, and useful feedback to help you become a better writer and thinker. You will be able to track your average exactly throughout the course. Each student is responsible for:
    • Completing Weekly Reading Assignments .
    • Completing Weekly assigned Activities (Questions, Internet Research, and Homework), and submitting them to the instructor.
    • Participating in the weekly on-line Discussion.
    • Completing a Final Proctored Examination.

    Assignments % of Grade

    • Weekly Tasks (8) 75%

    (100 points each for the first 7 weeks and 50 points for week 8)

    (Weekly Tasks consist of Discussion Participation and weekly Activities [Internet Research, Questions, and Homework Problems])

    • Proctored Final Examination (250 points) 25%

    Guidelines for selecting an acceptable proctor can be found at the Park University Web Site. For proctored examinations, photo identification is required at the time of the test. A proctor request form will be made available to you during the first weeks of class so that you can send your requested proctor to me for approval. Failure to take a final proctored exam (or submit your final project for some online graduate courses) will result in an automatic "F" grade. 

    Course Grading Scale - the total of all points received (total of all weekly assignments and final exam) will determine the student's letter grade as follows:

    A = 90- 100%
    B = 80-89%
    C = 70-79%
    D = 60-69%
    F = < 60%

Late Submission of Course Materials:

Submission of Late Work: There is a late submission penalty of 25% of the assignment value for each day late - see the course FAQs for more information on this policy.

Make-up Work: Because solutions to most of the assignments are published weekly along with submission critiques in order to provide rapid feedback, the nature of this course does not lend itself to any make-up work.

Classroom Rules of Conduct:

Academic Honesty

Academic integrity is the foundation of the academic community.  Because each student has the primary responsibility for being academically honest, students are advised to read and understand all sections of this policy relating to standards of conduct and academic life. 

Definitions

Academic dishonesty includes committing or the attempt to commit cheating, plagiarism, falsifying academic records, and other acts intentionally designed to provide unfair advantage to the students.

  • Cheating includes, but is not limited to, intentionally giving or receiving unauthorized aid or notes on examinations, papers, laboratory reports, exercises, projects, or class assignments which are intended to be individually completed.  Cheating also includes the unauthorized copying of tests or any other deceit or fraud related to the student's academic conduct.
  • Plagiarism involves the use of quotation without quotation marks, the use of quotations without indication of the source, the use of another's idea without acknowledging the source, the submission of a paper, laboratory report, project, or class assignments (any portion of such) prepared by another person, or incorrect paraphrasing. Please not that I submit a many of the papers that I get for this course to Turnitin for analysis.
  • Falsifying academic records includes, but is not limited to, altering grades or other academic records.
  • Other acts that constitute academic dishonesty include:
    • Stealing, manipulating, or interfering with an academic work of another student or faculty member.
    • Collusion with other students on work to be completed by one student.
    • Lying to or deceiving a faculty member.

Procedure

In the event of alleged academic dishonesty, an Academic Dishonesty Incident Report will be submitted to an Online Academic Director who will then investigate the charge.  Students who engage in academic dishonesty are subject to a range of disciplinary actions, from a failing grade on the assignment or activity in question to expulsion from ParkUniversityParkUniversity's academic honesty policy and related procedures can be found in full in the 2004-2005 Park University Undergraduate and Graduate Catalogs.

Course Topic/Dates/Assignments:
Readings, Overview, and Weekly Activities

Week 1: Introduction to Databasing and Query By Example (QBE)  
  • Readings: Text: Read Chapters 1, 2, (from our textbook, Eighth Edition) and the publisher’s student resources web site (at http://wps.prenhall.com/bp_hoffer_mdm_8/0,12126,3390077-,00.html - select the tab labeled “Seventh Edition QBE Resources” located on the left side of the screen) 7th Edition, Chapter 2 QBE material (pp. 68 - 70) and 7th Edition, Chapter 9 QBE material (pp. 375 –384).
  • Overview: During Week 1, we begin with an overview of the course covering the content and administration of the course. Database concepts and terms are introduced, as well as a brief history of database models used over the last 30 years. In Chapter 2, we briefly cover the steps taken in a database development and compare them with the steps for a typical software development effort. We see our first database application toward the end of Chapter 2 for the Pine Valley Furniture Company, which includes examples of database tables implemented in Microsoft (MS) Access (a popular PC based Database Management System [DBMS]). An example of the Graphical User Interface (GUI) for MS Access is shown on the publisher’s student resources web site (at http://wps.prenhall.com/bp_hoffer_mdm_8/0,12126,3390077-,00.html - select the tab labeled “Seventh Edition QBE Resources” located on the left side of the screen). This example under links for the 7th Edition, Chapter 2 QBE material (pp. 68 –70, Figures 2-15, 2-16 and 2-17) and Chapter 9 QBE material (pp. 375 –384, Figures 9 -10, 9-11, 9-12, 9-13, 9-14, 9-15, 9-16 and 9-17) provides a detailed look at a vendor’s implementation of Query By Example (QBE) as a GUI based interface to a relational database. The use of MS Access in this detailed example show the utility of this approach to ad hoc querying for a vendor produced DBMS.
  • Class Activities/Weekly Tasks (see topics for details): Discussion Topic Thread Participation and Activity Question(s).
Week 2: Data Modeling/Entity-Relationship Diagrams  

 

Week 3: Logical Database Design/Relational Model/Normalization 

 

Week 4: Structured Query Language (SQL) 
  • Readings: Text: Read Chapters 7 and 8.
  • Overview: During Week 4, Chapters 7 and 8 introduce the structural Query Language (SQL) as the direct database interface for relational databases. The data definition language (DDL) and data control language (DCL) are introduced, and the data manipulation language (DML) is explored in more detail so that the student is conversant in querying in SQL. Chapter 8 ends with a discussion of useful current and proposed programming constructs like triggers and procedures, and illustrates ways SQL can be integrated with other programming languages.
  • Class Activities/Weekly Tasks (see topics for details): Discussion Topic Thread Participation and Activity Homework Problems.
Week 5: Physical Database Design/Client-Server Architectures/Distributed Databases  
  • Readings: Text: Read Chapters 6, 9, 10, and 13 (from our textbook, Eighth Edition, only an initial part of Chapter 13 is present in our text), and read the rest of Chapter 13 on the publisher’s student resources web site at http://wps.prenhall.com/bp_hoffer_mdm_8/0,12126,3390077-,00.html - select the tab labeled “Chapters 13 –15” located on the left side of the screen. Then select from among the links to navigate to Chapters 13, 14 or 15. The complete version of Chapters 13, 14, and 15 are found through these links.Text: Read Chapters 6, 9 (except 375-384), 10, and 13.
  • Overview: During Week 5, we shift from logical modeling involving data and its structure constrained by business rules to physical modeling where we focus on how we will implement the database. In Chapter 6, look at providing estimates of permanent and random access memory sizes, and estimates of performance response times for typical database activities. We also discuss ways of increasing response time performance. Chapter 9 continues physical database design by considering the network environment in which the database will be implemented. The first consideration here is the type of architecture (i.e. client/server) in which to host the database. Various client/server architectures are examined ranging from file servers to the popular two and three tier designs. Chapter 9 ends with a discussion of popular application interfaces for databases. Chapter 10 discusses the web based popular alternative to the client/server architectures of Chapter 9 for hosting databases. Issues, such as security, and applications examples are provided for the internet environment associated with databases. Chapter 13 continues exploring the database network environment design by covering the aspect of distributed databases. The advantages gained by partitioning the tables in a large relational database are weighed against the networked complexity of data synchronization. Topics of data integrity, quality, concurrence, replication, committing changes, and back-up are introduced.
  • Class Activities/Weekly Tasks (see topics for details): Discussion Topic Thread Participation and Activity Internet Research.
Week 6: Data and Database Administration/Data Warehousing 

 

Week 7: Object Oriented Approach to Databasing 

 

Week 8: Object - Relational Databases and Final Proctored Exam
