  1. Rose-Hulman Archive Project Team 2 Eric Lewandowski Joseph Richey Jeremy Barton Todd Windler Jonathan Knez Steven Gregory JP Gonzalez

  2. Our Client • Logan Library • Richard Bernier • John Robson • IAIT • Sonny Kirtley

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

  4. The Old System

  5. Database Diagram of Old System Query: select * from IAIT.OBJECT “Samuel + 1985” Client Web Server Table of Results Formatted Results

  6. 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!

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

  8. Diagram of New System

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

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

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

  12. Demo • We will now see a search using our script

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

  14. Current Status • System Completed – Add Cosmetic Changes

  15. 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

  16. Time Distribution for Spring Quarter

  17. Time Analysis for Winter Quarter

  18. Risk Analysis Identification and Estimation High Probability E Moderate Probability A Low Probability D B, C Low Impact Moderate Impact High Impact

  19. 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
