A Service Oriented Information System: A Model Driven Approach

Generally the information system development is designing the systems with the use of visual design tools and takes the target modelling artefact as a basis to manually define the software application code. The process of mapping business requirements to the application code involves several parts that make the whole development process again very sensitive to errors. In this paper, we present a model-driven approach to overcome the gap between business requirements on one hand and service oriented architecture on the other. For this, we focus on the development of service oriented information system (SOIS) and a set of model transformation rules. Different ways of transforming a model into another exist. The choice of a target model differs according to quality criteria and is determined on the basis of specific requirements. The development process proposed is based on a BPMN meta-model, SOAML meta-model and a component meta-model. The approach leading elements are: the meta-modelling and automated mapping rules. Finally, we illustrate our proposal with a case study.
