Transcript of "CISA - Web based Course Information System software"

  1. 1. Web-based Course Information System supporting Accreditation using ASP.NET Master’s Project by Vidhya Sampath Kumaran Division of Computing Studies Committee: Dr. Timothy Lindquist (Chair) Dr. Kevin Gary Prof. Richard Whitehouse
  2. 2. Problem Statement <ul><li>Lack of Dynamic Course Information web pages in Div. of Computing Studies (DCST) </li></ul><ul><ul><li>Maintenance </li></ul></ul><ul><ul><ul><li>Requires HTML skilled user </li></ul></ul></ul><ul><ul><ul><li>Becomes time consuming </li></ul></ul></ul><ul><li>Lack of software tool in DCST for ABET Accreditation of programs </li></ul><ul><ul><li>Demonstration of Program outcomes satisfying ABET criteria (“Outcome-based evaluation”) </li></ul></ul>
  3. 3. Related Work <ul><li>TrueOutcomes: Web-based commercial software for outcome assessment </li></ul><ul><li>ASU BlackBoard and TrueOutcomes Integration </li></ul><ul><ul><li>Students of DCST </li></ul></ul><ul><li>EAssessment System </li></ul><ul><ul><li>University of Bridgeport school of Engineering </li></ul></ul><ul><li>Course Information System </li></ul><ul><ul><li>East Tennessee University </li></ul></ul>
  4. 4. <ul><li>Web-based Database-driven Course Information System supporting Accreditation (CISA) tool for DCST that provides: </li></ul><ul><ul><li>Single database to store course information and outcomes </li></ul></ul><ul><ul><li>Secured view of web pages to insert, update, and delete information </li></ul></ul><ul><ul><li>Public view of web pages to display dynamic course information and outcome mappings </li></ul></ul>Project Solution
  5. 5. <ul><li>Technologies Used </li></ul><ul><ul><li>ASP.NET 2.0 </li></ul></ul><ul><ul><li>ADO.NET </li></ul></ul><ul><ul><li>Languages : C# </li></ul></ul><ul><li>Software Used </li></ul><ul><ul><li>Visual Studio .NET 2005 </li></ul></ul><ul><ul><li>PostgreSQL 8.1 </li></ul></ul><ul><ul><li>Npgsql -.net data provider for PostgreSQL </li></ul></ul><ul><ul><li>Internet Information Services (IIS) 6.0 </li></ul></ul>Technologies & Software
