Fault Tolerance in Intranet Information Systems for Tertiary Health Institutions

Abstract

The critical nature of information and data in some systems like health sector requires a system that gives optimal tolerance to fault without trading off or compromising system integrity, availability and security in order for the system to afford greater efficiency. The main thrust of this work is to examine health system information flow and application(s) in the light of fault tolerance and come up with application software of higher tolerance to fault that can be deployed as an intranet in a tertiary health institution for sharing Patients’ Case Notes among care givers. Besides extensive literature review on the work, Ladoke Akintola University of Technology Teaching Hospital, one of the teaching hospitals in Nigeria, was chosen as a case study. The various departments and users are interviewed and interacted with in order to, among other things, gather system requirements. The software development technologies used are ASP.NET with Visual Basic as language and Microsoft SQL 2005 Express Edition. The platform used is Visual Web Developer 2008 Express Edition. The web server used is Internet Information System (IIS).
