Migrating a Legacy Application to the Web: the Sinfor Project

Abstract

Various approaches can be used to enable legacy applications to the Web. In particular, a number of data-intensive legacy applications as traditional application for business management, can't be simply described and structured in terms of html pages and links because of their complexity. In this scenario, new methodologies are devoloped to support the migration process.

The Ubiquitous Web Applications (UWA) Project is a research project founded by European Community about conceptual modeling of modern on-line applications: in this paper we describe the application of UWA in a real experience about the migration of a legacy data-intensive stand-alone application for customer's order management. Some of the possible migrating approachs and strategies are considered and discussed. Both design and implementation issues are considered in the paper, referring to a complete prototype we developed.

The results are rather general and can be easily applied to other migration projects.
