Distributed Data Bases

IS-262   Instructor:  Paul Lecoq

Time Monday through Friday, 7:30 to 8:30 AM

Return to Paul Lecoq's page

An in-depth investigation of database management in distributed E-Commerce environments.  Students are required to understand Data Base Theory and to be able to use SQL prior to entry to this class.  Students are also required to have a working knowledge of one or more network programming languages (Java, Java Script, Visual Basic, VB Script, or Perl prior to beginning this course.  Students will learn how to manage a professional DBM system and exercise its capabilities.  Students will also learn the fundamentals of distributed access to data bases via two-tier and n-tier architectures.  to be familiar with an applications data base manager (Access) and with Visual Basic.  The course will be segmented into two threads:

Major course task List:
The instructor will lead regular discussions in class, giving out assignments as appropriate.  In addition to these class related study tasks you are expected to complete the  assignments in a timely manner.

Learning Objectives:

To become effective in managing data base systems as used in E-Commerce environments, applying them to appropriate corporate needs.

Data Base Management Software management
In this thread the students will learn how to operate, manage, and create data bases in a professional DBMS such as SQL Server 7 or SQL Server 2000.  Instruction will be in-depth on the chosen DBMS but the students will be instructed on competitive DBMS such as Oracle.
Students will learn advanced techniques using SQL on appropriately normalized data bases.
Students will learn how to set up the DBMS for remote access.

Principles and applications of distributed Data Base Access.

Students will learn the principles of n-tier distributed Data Base systems and will implement representative 2 tier and n-tier access modules.  Students will use Visual Basic, VB-Script, Java Script, and/or Perl.



Course Schedule for the quarter



One Midterm and one Final exam. The primary evaluation criterion will be how well you perform the assigned tasks.

Major Course Tasks

Back to task list==Back to weekly schedule


    Class problem:

    You will be given a scenario with an incomplete set of business rules and objectives.  As a group (or groups) you will evaluate the companies organization and needs and propose a specific distributed database solution for them.

    Both a written and oral report on the solution are required.

    The basic Scenario:
    A new dot-com company is being formed to provide a unique service to a broad client base.
    The precise description of the business will be disclosed in class after everyone has signed a simulated non-disclosure agreement.
    The Company will require an interactive Web page with lots of CGI/ASP access to data bases describing their products and keeping track of the client base.
    Client interaction will be by E-mail, threaded discussions, and direct connection to a human specialist.  The class will design a seamless system for accessing all modes of interaction.

    The class will:

    • Analyze the problem:
    • Interact with Corporate representatives to define precise requirements
    • Research for off-the-shelf systems to do the job.
    • Design in-house developed system.
    • Perform cost/benefits tradeoff between development and purchase of the system
    • Implement the most effective solution
    • Test the solution under simulated real world conditions.

    Research Assignment

    You will be given a list of topics from which to choose.  Working in pairs or by yourself, you will explore books, the web, and anything else you can find to give a diffinitive oral report on your chosen subject.
    Show your notes at the time of your report for full credit

Assignments are due on hardcopy on the first day of the week in which the assignment is noted in the schedule. I will allow a grace period but if the assignment comes in after Wednesday they may suffer a 20% penalty. After Friday, 50% penalty.

You must turn in all assignments in order to pass the course, even if you get no points for the assignment.

In addition to handing in the assigned problems, you are expected to read all the chapter problems and convince yourself that you could do them if asked.  If you have trouble understanding them, bring them to class.


How do you know when you are done? How well have you done?

GRADING (These values may vary depending on how well we progress)

1 Test 100
9 projects 300 (1/2 on whether it works
1/4 on quality, 1/4 on testing) FINAL 200
Attendance & participation 100
Your grade on all work will be determined by linear interpolation between the lowest 4.0 and the highest 0.0.
Lowest 4.0 =~90%
highest 0.0 =~70%
