Uma abordagem de desenvolvimento baseada em modelos de arquitetura organizacional de TI: da semântica ao desenvolvimento de sistemas

Abstract

The management of organizations is a highly complex activity, since it requires the use of knowledge from several knowledge domains (including business process, information technology and infrastructure). In order to analyze how these domains are interrelated an Enterprise Architecture is essential. The main benefits of using Enterprise Architecture are: (i) to capture the essence and evolution of a business and its information systems; and (ii) to manage the alignment between the business and information systems in a cost-effective manner, possibly by revealing how business processes and information systems are interrelated. To address the alignment between business processes and information systems, several Model-Driven Development approaches enable designers to derive process-oriented systems directly from the business process models through automatic transformation. However, most of these approaches do not enable designers to explore the semantic richness of many Enterprise Architectural models (using only the control flow of business process models), and further define rather inflexible transformations. Moreover, many of these approaches to not clearly separate the development process into platform-independent and platform-specific steps, polluting business process models with platform concerns. This work proposes a novel Model-Driven Development approach to address the aforementioned issues. This approach enable the designers to (i) profit from the semantics of Enterprise Architecture models throughout the system development process; (ii) to apply parameterization in pre-defined transformations and; (iii) to clearly divide the development process into platform-independent and platform-specific steps.
