3. Motivation Why computer minor/certificate?
6 among top 10 are computer related! ( and-worst-jobs-of-2013/2013/05/03/fccd6a8e-b1ab-11e2-bbf2- a6f9e9d79e19_gallery.html#photo=1)

4. Why this section? Job hunting Something help you to stand out!
WCU graduated
vs.
UPenn, Temple, Drexel, …
Something help you to stand out!
How can I introduce you?

5. Tell you what I see at Temple
Knowledge?
Communication?
Abstraction & critical thinking
Passion and motivation
I just need 3 credits
How much I need to do for getting an ‘A’
I need to care my GPA

6. Critical thinking, abstraction, motivation
How can I obtain all these
How can I prepare myself
How can I prove myself

7. Research project
Critical thinking, communication, etc.
Real competition, deadline, pressure
More realistic system, complex programming, for instance,
Student opportunities:
Sponsorship
NSF, NSA, etc
Industry interns

8. No pain, no gain Happy ending
Need to handle those things coming from pressure: frustration, upset, madness, etc.
Looking for solution, not excuse.
Deadline!

9. Deadline of assignment
Class website (including ppt)+ google search
Hands-on experience
Group discussion

10. Topics and schedule
See syllabus
Database
data
Query request
DBMS

11. Integration
Administration
Security & encryption
Privacy & inference
Transaction & injection
Sketching & hashing

12. Know how simply the system works, rather than memorizing all those in the manual.
Use those generally supported phases, statements, or rules, rather than focusing on trick plays (For instance, no join operator!)
Use class design to better organize the data relationship, reducing the data vulnerability while fully maintaining all the query requirements.

13. Advanced SQL (nested SQL) Normalization
ACCESS -> SQL
How this GUI interface works?
Advanced SQL (nested SQL)
Who can have the control of table?
Normalization
Easy to do
Ambiguous in use for real application
Class design (UML) – alternative design
Use case
Class diagram
Multiple layer
Indirect Database
Server – MySQL
Client – JDBC

14. API integration

15. Databases Relational DB Non-relational DB NonSQL DB
The dependency relation among data
Non-relational DB
Without such a relation
NonSQL DB
More complicate relation structure
e.g., Kobo, Playtika (mobile service)
Fast third-party data aggregation
Globally distributed data repository
E-commerce and internet burstness
Game (data intensive applications)
Ad targeting (social networks)

16. Data information
Share the experience of data processing: Word, Power point, Excel, IE, and etc.

17. Word <Insert> <Copy> & <Paste> <Ctrl><p>
<Symbol> ≥ 
<Copy> & <Paste>
<Ctrl> <c>  <Ctrl> <v>
<PrtSc> & <Alt> <PrtSc>  <Ctrl> <v>

31. Problem
How to manage and locate the wanted information?

32. Directory & files
