Software Modernization of Legacy Systems for Web Services Interoperability

Abstract

Software maintenance is an inevitable process due to program evolution (Lehman & Belady, 1985). Adaptive maintenance (Schenidewind, 1987) is an activity used to adapt software to new environments or new requirements due to the evolving needs of new platforms, new operating systems, new software, and evolving business requirements. For example, companies have been adapting their legacy systems to Web-enablingenvironments of doing business that could not have been imagined even a decade ago (Khosrow-Pour & Herman, 2001; Werthner & Ricci, 2004).
