5. Habitat for Humanity PURDUE UNIVERSITY Rev. 01 Fall 2004 National Database Team John Horst Jeff Ross Noah Solomon Arthur Thompson

6. Habitat for Humanity PURDUE UNIVERSITY Problem Statement Problems for HFHI –No centralized survey administration and data collection system. Some local affiliates do their own surveying, but data is not shared. –There is no concrete quantitative data, currently, to show the benefits of the Habitat program to the community, both locally and nationally. –Homeowner information and responses must be securely collected, transferred, and analyzed to be in line with Habitat’s organizational mission.

7. Habitat for Humanity PURDUE UNIVERSITY Methodology Proposed Solution –Having a centralized secure server database for survey information and homeowner responses –Homeowner ID’s will be requested from the server but will be kept in paper records as to ensure the security of the information being recorded. –The web-based program will consist of three main parts: A Survey Generator Homeowner Response Collection\Input Statistical Analysis

8. Habitat for Humanity PURDUE UNIVERSITY Technical Solution The current program relies on a single centralized database to hold the surveys, responses, and a list of questions and answers. It also relies on a web application to act as the front end to the database. HFHI standards are to use Microsoft products. We have adhered to HFHI standards. We are using ASP.net and MS SQL for this tool.

9. Habitat for Humanity PURDUE UNIVERSITY Tasks Completed –Beta Version Written (Spring 2004) –Reestablished communication (Fall 2004) –Design Documentation (Fall 2004) –Server up and running (Fall 2004) –Team has software (Fall 2004) –Documentation for all Previous Design Steps (Fall 2004) Outstanding –Version 1.0
