Motivation Why computer minor/certificate? 6 among top 10 are computer related! (http://www.washingtonpost.com/business/economy/the-10-best- and-worst-jobs-of-2013/2013/05/03/fccd6a8e-b1ab-11e2-bbf2- a6f9e9d79e19_gallery.html#photo=1)

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?

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 http://www.youtube.com/watch?v=lYtxA_IfQMk

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

Research project Critical thinking, communication, etc. Real competition, deadline, pressure More realistic system, complex programming, for instance, http://www.cis.temple.edu/~jiang/RSU_van.pptx. Student opportunities: http://www.cs.wcupa.edu/~zjiang/student_info.htm Sponsorship http://www.cs.wcupa.edu/~zjiang/ISC2013.pptx. NSF, NSA, etc Industry interns

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

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

Topics and schedule See syllabus Database data Query request DBMS

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

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.

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

API integration

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)

Problem How to manage and locate the wanted information?

Directory & files Multiple descriptors/requirements  single name, single index, single data entity

Database Systems & Access Shelly, Cashman, Pratt, “Microsoft Office Access 2007 Comprehensive Concepts and Techniques”, Course Technology Page: AC14 Page: AC44 Exercise 1: http://www.cs.wcupa.edu/~zjiang/cst221_l ab1.doc
