Laying the Foundation for Web Services over Legacy Systems
Abstract
As the use of the World Wide Web becomes more pervasive within our society,
businesses and institutions are required to migrate a wide range of
services to the web. Difficulties arise where there are requirements to
integrate existing systems within the migrated and often-extended web based
services. The Institutionally Secure Integrated Data Environment (INSIDE)
project is addressing the problems and issues surrounding the development
and delivery of web based services for "joined up systems" for institutions
within Higher Education (HE). The project is working with a variety of
existing information systems, e.g. student record systems and managed
learning environments, at two universities. To better understand the
requirements for an integrated web based service, a common business
process, the registration of new undergraduate students, has been analysed
and modelled at both sites. Progressing from initial informal models to
more formal models in a systematic way, following a meta-process
incorporating good practice from domain analysis and requirements
engineering has allowed the project to lay the foundation for its
development of web-based services.
