File System and DBMS Code Take Poll on Who has had CS125 [C programming], CS225 [C++ programming], CS315 [Data structures] ALL must Learn SQL and Use PRCLab Web Interface and Command Line Interface

Assignment #5 Options [Teams] – Dig Deeper into DBA SQL Security [Non C/C++ Programmer

Option] – DBE Design to Deploy a DDL Schema and Populate with DML Test

Data – Build a C/C++ Connector [or Java JDBC]

ALL must Learn OOA/OOD and Basic OODBMS Concepts

PRClab – Linux for C/C++ Option #1 – Use PRClab, prclab.pr.erau.edu via SSH – Recommend Putty connection with SSH and X11 forwarding – Code Development (GCC/g++, Make, etc.) -

http://mercury.pr.erau.edu/~siewerts/cs317/documents/Linux/ – Debugging C/C++ Source Code using DDD

(http://www.gnu.org/software/ddd/manual/html_mono/ddd.html ) – Verification and Validation of C/C++ Implementations – General Linux System (RHEL 6.5) – http://prclab.pr.erau.edu/adminer.php (PHPAdmin login) – servicedesk@ellucian.com – For Help with PRClab login, etc.

Option #2 – Use Virtual-Box Linux with Centos 6.5 Install of Ubuntu 14.04 LTS (Both Supported) – Must Have Windows, Macintosh or Linux Personal PC – http://mercury.pr.erau.edu/~siewerts/cs317/documents/Linux/Linux-

Login to MySQL via Web http://prclab.pr.erau.edu/adminer.php

Sign up for account today!!! Explore Read Tutorial Docs - http://dev.mysql.com/doc/index-topic.html

Login to MySQL via SSH Shell (Putty)

In Case You Want More (NOT REQUIRED) Install Oracle Virtual Box Install Centos 6.5 or Ubuntu 14.04 LTS Install MySQL Install Apache and PHP Setup PHPAdmin on localhost

Next Time … DBMS vs. File System (read DBMS Chapter #1) – Come to Class Prepared to Discuss – Why is DBMS Better then File System – Why do we Use File Systems still? – What is NoSQL? (Not in Book, http://en.wikipedia.org/wiki/Nosql) – Structured vs. Unstructured Data? – For Discussion

Assignment #1 Discussion – I will Post Every Other Wednesday, We’ll Discuss, Due

Following Week on Friday – Late Assignments – 10% Penalty for Monday Turn-in, After

Monday, only with Instructor Permission
