Concepts for Modelling Enterprise Architectures : Research initiative that aims to provide concepts and techniques to support enterprise architects in the visualisation, communication and analysis of integrated architectures. Depth study of SOA , ROA And EDA. Study the Domain Driven Design methodology to ensure that software architecture becomes a cross-cutting concern. The choice of technology and architecture can be fixed in the middle of the project therefore the Dev team has enough knowledge to choose the right one. Put a hexagonal architecture in which the domain is central and technologies are used as adapters and ports. Depth study of the pattern MVC2, MVP, MVVM. Develop a micro architecture MVC2 in aspect-oriented so that the architectural style is isolated in aspects and woven on runtime. This solution has solved the dispersion and the tangle of pattern s code.
