Today’s Agenda
• Define The “Opportunity”– Where– What– Why– Decision– Challenges– How– Impact
![Page 6: Alabama Association for Institutional Research Annual Conference April 2007 Institutional Research: Is It Rocket Science?](https://reader035.vdocument.in/reader035/viewer/2022062422/56649e7c5503460f94b7e79a/html5/thumbnails/6.jpg)
Where We Were In 2001• Institutional Research
Website 2001– Static pages– Static data
• Ad Hoc Reports– Only in response to a
specific request
![Page 7: Alabama Association for Institutional Research Annual Conference April 2007 Institutional Research: Is It Rocket Science?](https://reader035.vdocument.in/reader035/viewer/2022062422/56649e7c5503460f94b7e79a/html5/thumbnails/7.jpg)
What We Wanted To Accomplish• Information On
Demand– Make many of our ad
hoc reporting mechanisms available as interactive or drill down tools on our website
![Page 8: Alabama Association for Institutional Research Annual Conference April 2007 Institutional Research: Is It Rocket Science?](https://reader035.vdocument.in/reader035/viewer/2022062422/56649e7c5503460f94b7e79a/html5/thumbnails/8.jpg)
Why We Wanted To Accomplish This • Program Review
– Accurate, up to date information
– Aggregate and granular data specific to particular academic programs
– Individual departments need to generate and analyze their own data
![Page 9: Alabama Association for Institutional Research Annual Conference April 2007 Institutional Research: Is It Rocket Science?](https://reader035.vdocument.in/reader035/viewer/2022062422/56649e7c5503460f94b7e79a/html5/thumbnails/9.jpg)
The Decision To Develop Our Own Tools • Packaged vs. Custom
– Crystal Reports, SAS, Cognos, DiscovererCostsLearning curve
– Web ApplicationsMenu basedResult oriented

Challenges We Faced• Technology• Utilization• Communication• Business Practices
![Page 11: Alabama Association for Institutional Research Annual Conference April 2007 Institutional Research: Is It Rocket Science?](https://reader035.vdocument.in/reader035/viewer/2022062422/56649e7c5503460f94b7e79a/html5/thumbnails/11.jpg)
Challenges We Faced• Technology
– Data SourceConsistent, centralized,
localExtract and present
accurate, up to date information
![Page 12: Alabama Association for Institutional Research Annual Conference April 2007 Institutional Research: Is It Rocket Science?](https://reader035.vdocument.in/reader035/viewer/2022062422/56649e7c5503460f94b7e79a/html5/thumbnails/12.jpg)
Challenges We Faced• Technology
– SecuritySecure databaseSecure connectionsSecure presentation
– No personally identifiable information
– .NET won’t serve source files
![Page 13: Alabama Association for Institutional Research Annual Conference April 2007 Institutional Research: Is It Rocket Science?](https://reader035.vdocument.in/reader035/viewer/2022062422/56649e7c5503460f94b7e79a/html5/thumbnails/13.jpg)
Challenges We Faced• Technology
– CompatibilityOracle / Microsoft
connection issuesWe were successful with
ODP.NET and ODBCWe were unable to
employ OLEDB successfully in our environment
![Page 14: Alabama Association for Institutional Research Annual Conference April 2007 Institutional Research: Is It Rocket Science?](https://reader035.vdocument.in/reader035/viewer/2022062422/56649e7c5503460f94b7e79a/html5/thumbnails/14.jpg)
Challenges We Faced• Utilization
– What reports will be most useful?
![Page 15: Alabama Association for Institutional Research Annual Conference April 2007 Institutional Research: Is It Rocket Science?](https://reader035.vdocument.in/reader035/viewer/2022062422/56649e7c5503460f94b7e79a/html5/thumbnails/15.jpg)
Challenges We Faced• Communication
– Must have a good working relationship with database administrators and users
– Systems Development Life Cycle (SDLC)
![Page 16: Alabama Association for Institutional Research Annual Conference April 2007 Institutional Research: Is It Rocket Science?](https://reader035.vdocument.in/reader035/viewer/2022062422/56649e7c5503460f94b7e79a/html5/thumbnails/16.jpg)
Challenges We Faced• Business Practices
– Proactive vs. reactive– Transitioning to a
systems development orientation
– User involvement and education
![Page 17: Alabama Association for Institutional Research Annual Conference April 2007 Institutional Research: Is It Rocket Science?](https://reader035.vdocument.in/reader035/viewer/2022062422/56649e7c5503460f94b7e79a/html5/thumbnails/17.jpg)
How We Developed The Solution• Data Source
– Student Information Reporting System (SIRS)
– Curriculum Inventory (CIR)
– BannerAdmission Enrollment Registration
![Page 18: Alabama Association for Institutional Research Annual Conference April 2007 Institutional Research: Is It Rocket Science?](https://reader035.vdocument.in/reader035/viewer/2022062422/56649e7c5503460f94b7e79a/html5/thumbnails/18.jpg)
How We Developed The Solution• Database
– We Use Oracle 10g v2, 9.2– Other database products,
such as MySQL or SQL Server, will also support dynamic web applications
– MS Access and MS Excel probably won’t support dynamic web applications
![Page 19: Alabama Association for Institutional Research Annual Conference April 2007 Institutional Research: Is It Rocket Science?](https://reader035.vdocument.in/reader035/viewer/2022062422/56649e7c5503460f94b7e79a/html5/thumbnails/19.jpg)
How We Developed The Solution• Data Extraction
Queries– Because we use an
Oracle database, we write our queries in SQL and PL/SQL
– There are effective alternatives such as Java, C#, Visual Basic and others
![Page 20: Alabama Association for Institutional Research Annual Conference April 2007 Institutional Research: Is It Rocket Science?](https://reader035.vdocument.in/reader035/viewer/2022062422/56649e7c5503460f94b7e79a/html5/thumbnails/20.jpg)
How We Developed The Solution• Presentation
– We use ASP.NET, Visual Studio and VB.NET 2003 and 2005
– We run IIS with framework 1.1 and 2.0
– We also employ Extensible Markup Language (XML), Extensible Stylesheet Language (XSL) and Cascading Style Sheets (CSS)
