Our Client Logan Library –Richard Bernier –John Robson IAIT –Sonny Kirtley

The Project Redo the web interface for the RHAP Create a friendly user interface Fix search engine.

The Old System

Diagram of Old System Client Web Server Database “Samuel ” Query: select * from IAIT.OBJECT Table of Results Formatted Results

Dislikes of Old System Too slow. –Client receives entire database then does its own searching –Memory intensive Too complicated Theme inconsistent with rest of Library page Does not work!

Requirements of New System It must work It must use the existing database Make it easily expandable The rest is up to us

Diagram of New System

Completed Work Search Database Fully Functional Web Interface Return Results and Display in Meaningful Way

Implemented Extras Static Web Portions Contained In Templates Audio Streaming Supported Help Synopsis Wildcard Search Capability

Extras (In Progress) Functional Browsing Tree Limit Results (10 per page)

Demo We will now see a search using our script

Approach Split Into Two Teams Individual Parts Done By Sub-Teams Workload Dynamically Allocated Amongst Team Members Based on Availability

Current Status System Completed – Add Cosmetic Changes

Lessons Learned Maintenance and Modification Is Tougher Than Creation Constraints Dictate Design Decisions Communication With Client Is Necessary Complete Core Project First, Add Extras As Time Permits

Time Distribution for Spring Quarter

Time Analysis for Winter Quarter

Risk Analysis Identification and Estimation IDRiskProbabilityImpactA Decision to change the DB field structure MH B IAIT decides to stop supporting Perl LH C Client does not approve of final project LH D The client or IAIT might need to modify Perl code LM E Modifying our Perl code breaks the system HH A E DB, C Low Probability Moderate Probability High Probability Low Impact Moderate Impact High Impact

Risk Analysis Mitigation A - Decision to change the DB field structure –Modify parsing script and searching script –Migrate records from old DB to new DB field structure B - IAIT decides to stop supporting Perl –Re-write scripts in other languages IAIT supports C - Client does not approve of final project –Meeting were held after implementing each feature D - The client or IAIT might need to modify Perl code –Heavy documentation in Perl code E - Modifying our Perl code breaks the system –Code is documented –In-depth Technical Document
