A multi-layered software architecture model for building software solutions in an urbanized information system

The concept of Information Systems urbanization has been proposed since the late 1990’s in order to help organizations building agile information systems. Nevertheless, despite advantages this concept, it remains too descriptive and presents many weaknesses. In particular, there is a lack useful architecture models dedicated defining software solutions compliant with systems principles rules. Moreover, well-known do not provide sufficient resources address requirements constraints urbanized paper, we draw on “information city” framework propose model - called 5+1 Software Architecture Model which helps solutions. This improves well-established allows integration new architectural paradigms. Furthermore, contributes implementation several ways. On one hand, devotes specific layer applications reuse. other system agility scalability due its conformity separation concerns principle.
