Zachman Framework Enterprise Modelling of the Estonian National Health Information System

Abstract

The desire by various societies, organizations and countries of the world to ensure a much better healthy status and systems has led to the development of information systems. Many a time, these systems have been treated as individual entities rather than as an enterprise resulting in a lack of clear cut goals and definition of what these systems are meant to do. The Zachman Framework is a good modeling tool to identify the purpose, goals and components of any enterprise. The framework has successful modeled the Estonian National Health Information System leading to the identification of the Estonian government, healthcare institutions, Estonian insurance fund, information technology specialist and industries, citizens and legal residents among the many stakeholders of the national health information system. Existing relationships among these stakeholders, the many different data and service functions provided by health information systems were also identified
