Why are you here?

• It is a required course!– Pre-requisite for other advanced courses

• Why did IST make this course required?– Importance in organizing data, information, and

knowledge• And hopefully there is more!

How do you store your personal data?

• Example: Address book

IST210 6

Organization of the data is important

• Have you ever thought about how the data is organized behind these systems? – Class schedule system: http://schedule.psu.edu– Online shopping system: www.amazon.com

• Huge amount of data need to be well organized: we need a database to efficiently and accurately modify and query the data

IST210 7

Organization of the data is important

• Web 2.0– Youtube, Facebook, Twitter, Wikipedia…

• How to deliver Web-2.0 services?– The central piece -- database

• Manage complicated data– Youtube.com: video clips, users, comments, tags, …– Facebook.com: profiles, photos, music, comments, …

– Web service: search and data retrieval

IST210 8

Using Data for Competitive Advantage

• Success of companies relies on – Data: Wall Street companies– Flow of data: FedEx and UPS– Capabilities to extract information from data

• “What Wal-Mart Knows About Customers' Habits”

• "How Target Figured Out A Teen Girl Was Pregnant Before Her Father Did” [Video]

beer"And the pre-hurricane top-selling item was _______.“ -- Linda M. Dillman, Wal-Mart's chief information officer

Readings for Lectures• Textbook: Database Concepts by Kroenke &

Auer/ Pearson, 7th edition

Previous editions: content should be similar, assignments might be different

IST210 12

In Classes

• Attendance– Attendance is required for every class!– Attendance check: 6% in final grading– If you are not able to attend class with reasonable

excuse, instructor or TA should be notified before class

• Class rule: Computers will be taken control during lecture time

IST210 13

After Classes

• Study groups strongly encouraged– Discuss general approaches, not specific answers to

homework questions

• Keep track of up-to-date IT news and events– See how they can be related to this course

Assignments

• Five homework assignments– Key concepts in database

• Three programming assignments– Essential skills to apply the concepts to solve real-world

problems

• Due: one week after an assignment is given• Independent work!

• Do not exchange your answers with your classmates!• Do not search for solutions online!• University policy on Academic Integrity: http

Project

• A web-based database system to demonstrate what you have learnt– Group project on an idea developed by your group– Database design and implementation– Innovation is strongly encouraged!

• Group will be assigned based on your technical backgrounds– Finish the survey on ANGEL before next class!– Group size: 4 students

IST210 16

Project (cont.)

• Five stage progress reports– Each has a very specific problem related to the project

• One final report – Put all progress reports together– Include the final result of your design

• Final in-class presentation

IST210 17

Project (cont.)

• Hands-on learning– Coding is an integral part of the class• HTML, PHP, SQL• Templates and examples will be provided

– No coding experience• Work hard• Start early• Don’t panic, we will help you

– come to classes and come to office hours!

IST210 18

Coding in Fun

Never Give Up!

Submit Your Assignments

• All assignments must be submit online through ANGEL before deadline– Cut-off time on ANGEL: midnight– Strict late submission penalty• After the deadline but less than 24 hours: 10% penalty• More than 24 hours but less than hours late: 30%

penalty• No submission are accepted more than 48 hours late

IST210 20

Exam

• Midterm: Chapter 1-3• Final Exam: Everything we covered in class,

with more focus on Chapter 4-5

IST210 21

Grading

• Five Homework Assignments: 15%• Three Programming Assignments: 9%• Project: 35%• Exams: 35% = 10% (Midterm) + 25% (Final)• Class attendance: 6%

IST210 22

Grading: Project• Group grade– 3% for each progress report (total 15%)– 10% for the final report– 10% for the final presentation

• Individual adjustment– For each report: 30% is related to individual

contribution and involvement.• Done your part of work: 15%• Participation: 15%

IST210 23

Some Challenges You Will Face …• Individual assignments

– Some are time-consuming– Make good use of the office hours

• Programming– HTML, PHP, SQL– Do not worry about grading if zero experience

• 9% individual programming assignments• Projects are done as a team • No programming (HTML/PHP) in midterm exam and final

• Team project– This project is not something you can finish within 3 days, not even 3

weeks!– Team work is the key.

Team Work: Case Study

• Every semester, after finishing the project, I asked each team to write down what they have learnt… and here’s what one team say:

StudentA (the “zero-experience” guy): I haven’t had very much coding experience. … However, working in this smaller group helped allow me to ask specific questions that I maybe didn’t know how to ask before. [StudentB] was extremely helpful with the SQL statements. [StudentC] helped clarify all of the PHP trouble that I was having in the beginning of the semester…. All in all it was a great experience and I’m really proud of the end result.

Team Work: Case Study

StudentB (the “average” guy): …Working with [StudentA] and [StudentC] helped clarify some of the questions I had and really gave me the addition hands on experience that I needed in working with PHP…. To complete this project a lot of teamwork was needed. Each team member was able to use their strengths and help others with their weaknesses.

StudentC (the “genius”): Obviously coming into this class with an extensive programming background and years of coding under my belt, much of the HTML and PHP was not at all a challenge to me. Early on I knew this would be the case and so I really pushed myself to do something really awesome, something that would actually be a rewarding challenge for myself, and hopefully my team as well…. I was extremely impressed with the results…including backend PHP and SQL done exclusively by the oh so awesome [StudentA] and [StudentB].
