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 the authors, they 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.
