—Hospital information system, as an integrated system consists of complex, diverse, and heterogeneous information systems, which supports all clinical, administrative, and financial activities of patients; therefore, it faces interoperability problems, which is a critical feature of data sharing and integration. In this regard, a reference architecture will be presented for the integration of different systems in the hospital which comprises system, information and software architecture. This architecture emphasizes interoperability with eight layers of user interface and application, services, data collection and storage, integration, external application systems, communication and information infrastructure, management, and security/privacy, based on service orientation. It will be evaluated by ATAM method, based on ten scenarios. It shows the presented architecture will satisfy all functional and non-functional requirements such as interoperability between different information systems, reduction of information redundancy and development cost and time, scalability and accessibility.

Nowadays in the business world, all levels of all organizations need a concise planning. Regarding high-speed growth in globalization and competition trend, moving the organizations to the creation of integrated software systems with using latest technologies is a necessity. One of the most significant among the above-mentioned software systems is ERP. Both SOA and cloud deals with delivering services to business with improved agility increased speed and reduced cost that can lead to greater innovation and effective returns on investment. In this paper, after study about functional and nonfunctional requirements of ERP systems, by a framework, It will be study and research about achievement in ERP systems after engaging SOA and cloud computing and their impacts on ERP. Such that these impacts will resolve so many of shortages and needs of conventional ERP as well as reduction of risks and costs of implementation of ERP in organizations. Finally, we used ATAM for evaluating the framework. The idea of the experts in both business and ICT gathered by questionnaire and the data analyzed via TOPSIS method. Similar research for using strength of SOA and cloud computing in traditional ERP in shipping industry is a novelty.
