Big data has gained popularity in recent years, with increased interest from both public and private organisations including academics. The automation of business processes led to the proliferation of different types of data at various speeds through information systems. Big data is generated at a high rate from multiple sources that can become complex to manage with challenges to collect, manipulate, and store data with traditional IS/IT. Big data has been associated with technical non-technical challenges. Due to these challenges, organisations deploy enterprise architecture as an approach to holistically manage and mitigate challenges associated with business and technology. An exploratory study was done to determine how EA could be used to manage big data in healthcare facilities. This study employs the interpretive approach with documentation as the analysis. Findings were governance, internal and external big data sources, information technology infrastructure development, and big data skills. Through the different EA domains, big data challenges could be mitigated.

Enterprise Architecture Framework

The Mobile Enterprise is a new form of enterprise in the contemporary mobile era. Although several well-known enterprise architecture frameworks are used by enterprises, it is apparent that there is no industry standard available to enable an enterprise to transform its business processes to incorporate mobile technologies to advantage. This article presents a conceptual Mobile Enterprise Architecture Framework and supporting methodology and process model which can aid enterprise decision makers to evaluate the business values, and analyze the risks and other critical business and technical factors for enterprise mobile initiatives and mobile transitions. The framework covers both the enterprise and mobile enterprise architecture domains that represent the Enterprise, Business, and Mobile Adoption levels. The goal at the Enterprise Level is to obtain a mobile enterprise and the technologies adopted at the Mobile Adoption Level are the different mobile technologies to be incorporated. Each level contains some important components impacting the mobile enterprise transformation. The methodology and process model cover the Strategy, Analysis, Design, Implementation, and Maintenance stages for each mobile initiative, and were validated in a research project against some Ontario Government mobile initiatives.

Enterprise Architecture Framework

The modeling of Information Systems in general, and Web Information Systems (WIS) especially, is a permanent issue so that there have been already several attempts and proposals for representing various facets of WIS. In our proposed approach, we focus on the organizational and business activity modeling and we concentrate on documents that represent the information of enterprises in the form of unstructured and semi-structured documents. The compilation of documents mirrors implicitly or explicitly the structure of enterprises, the interrelationship of business processes, and activities and tasks within processes. The documents represent, at the same time, the system roles along with tasks and activities. Our modeling approach concentrates on the co-existence and co-operation of documents and activities of business. The Story Algebra, or more generally the process algebra approach provides a formal framework that promises a formal describing method for modeling precisely the event triggered processes coupled with data in document format within an Enterprise Architecture Framework.

Enterprise architecture has had a resurgence of interest in the IT community in the past ten year; in part because of a mandate for federal agencies of the United States government and in part because of the complexity of managing today’s information systems environments. It has become a critical component of an overall IT governance program to provide structure and documentation to describe the business processes, information flows, technical infrastructure and organizational management of an information technology organization. Many different enterprise architecture frameworks have emerged over the past ten years. Two of the most widely used enterprise architecture frameworks (the Zachman Framework and the Federal enterprise architecture framework) are described and their ability to meet the security and privacy needs of an organization is discussed. These frameworks represent a contrast of industry and government perspectives in addressing issues of key importance to senior IT leadership.

A Company

Utilization of information systems and information technology is needed in supporting business processes of a company, because the information system is one of the important things in the key to success of a company. Along with the development of information systems have an information system architecture model, where the information system architecture is necessary to plan the information system architecture to be built in the future, where the information system architecture as a spear to improve the competitiveness of a company with other companies.             PT. Ma'soem Arias is one of Pertamina lubricant distributor in West Java. The business activities carried out are to sell Pertamina lubricants to direct customers and direct lubricant procurement from Pertamina's producers. PT. Ma'soem Arias until now in carrying out its business process has not used the information system so needed an Enterprise Architecture planning for PT. Ma'soem Arias.Enterprise architecture model used in this research is by using Oracle Enterprise Architecture Framework (OEAF) model. The advantages of OEAF is to use object oriented concept, where the concept approaches the problem from the perspective of the object and not the perspective of the functional so it is easy to be understood. The method used is Oracle Architecture Development Process (OADP) method, where OADP method has several stages, ie from start of study about business architecture, architecture vision, current state architecture and future state architecture.The result of this research is recommendation of information system of PT. Ma'soem Arias is a blueprint for enterprise architecture planning that succeeds in defining 4 main business processes, the data architecture produces 24 entities, 4 applications and for its technological architecture produces technology architecture proposal.

It has become a critical component of an overall IT governance program to provide structure and documentation to describe the business processes, information flows, technical infrastructure, and organizational management of an information technology organization. Many different enterprise architecture frameworks have emerged over the past 10 years.

In its commitment towards Sustainable Development Goals, India envisages comprehensive primary health services as a key pillar in achieving universal health coverage. Embedded in siloed vertical programmes, their lack of interoperability and standardisation limits sustainability and hence their benefits have not been realised yet. We propose an enterprise architecture framework that overcomes these challenges and outline a robust futuristic digital health infrastructure for delivery of efficient and effective comprehensive primary healthcare. Core principles of an enterprise platform architecture covering four platform levers to facilitate seamless service delivery, monitor programmatic performance and facilitate research in the context of primary healthcare are listed. A federated architecture supports the custom needs of states and health programmes through standardisation and decentralisation techniques. Interoperability design principles enable integration between disparate information technology systems to ensure continuum of care across referral pathways. A responsive data architecture meets high volume and quality requirements of data accessibility in compliance with regulatory requirements. Security and privacy by design underscore the importance of building trust through role-based access, strong user authentication mechanisms, robust data management practices and consent. The proposed framework will empower programme managers with a ready reference toolkit for designing, implementing and evaluating primary care platforms for large-scale deployment. In the context of health and wellness centres, building a responsive, resilient and reliable enterprise architecture would be a fundamental path towards strengthening health systems leveraging digital health interventions. An enterprise architecture for primary care is the foundational building block for an efficient national digital health ecosystem. As citizens take ownership of their health, futuristic digital infrastructure at the primary care level will determine the health-seeking behaviour and utilisation trajectory of the nation.
