A Meta-Model for Migrating a Legacy Information System based on Procedural Software Architecture towards Service Oriented Architecture

During several years, the computing environments became more complex and more heterogeneous because of the diversity of customer’s needs and of the technological evolutions. The agreement between applications and different technologies became a critical activity. So, to face this problem of interoperability, companies often resort to the solutions of enterprise application integration (EAI). In what concerns us, we consider the EAI as being at the same time the strategy and the process that companies allow to reach a solution of optimal integration of the various heterogeneous, autonomous and distributed applications. In this context, this paper consists on presenting a generic meta-model for integrating legacy applications with service oriented architecture. Indeed, to resolve the problem of interoperability between applications, this meta-model aims at capitalizing on procedural legacy applications and their integration into modern environments.
