… two primary goals for students; the first goal is to learn the fundamentals of relational, object-relational and object-oriented database systems and the second goal is to have hands-on experience on database design, implementation, management and programming. http://mercury.pr.erau.edu/~siewerts/cs317/ http://mercury.pr.erau.edu/~siewerts/cs317/CS317-Syllabus-Fall-15.html Sam Siewert 5

File System and DBMS Code Take Poll on Who has had CS125 [C programming], CS225 [C++ programming] ALL must Learn SQL and Use PRCLab Web Interface and Command Line Interface Assignment #5 Option to Work with C/C++ for B-Tree Assignment #5 Option to Dig Deeper into SQL Security [Non C/C++ Programmer Option] ALL must Learn OOA/OOD and Basic OODBMS Concepts Sam Siewert 7

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-

MySQL on Linux (LAMP) Skills

Introduction Session (File System vs. DBMS)

File System Concepts – Review? Name Space Meta-Data File-Data I-nodes Blocks with Byte Offsets Belong to Name Space Files

Sam Siewert 13

Make a File System mkfs –t ext3 /dev/sdb1 Install Name Space and Metadata on Volume

Sam Siewert 14

Use a File System Block Access via dd in Linux – e.g. Clone Volume Name Space Access via Shell or Browser

MySQL Command Line and PHPAdmin Why and How is a RDBMS Different?

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 Connolly-Begg 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
