The academic program The Intensive English Language Program (IELP) at the University of New Orleans (UNO) offers one of the most effective and diverse language programs in the United States. This thesis is to report the development of the Webbased database application that manages admissions, students learning progress, and course offering of this program. The system development followed a simplified Unified Process for Software Development (UP) using the Unified Modeling Language (UML) models such as the requirement catch model – use cases, the analysis model – activity diagrams, and the design model –communication diagrams. The new system has met and exceeded all the business requirements and has been operating to support the further growth of the IELP at UNO. Significant attention has been given to information security; multiple techniques have been applied in addition to the security measures enforced in the hosting environment – the University Computing Center.
