Executive Summary
The following report is all about an analysis of electronic health record system which has been
developed by the approach of Enterprise architecture reference. This particular approach is
used on large scale basis for controlling the project from initial or beginning phase to closing
phase. In a sequential way the diagrams have been provided and they have used for describing
the essential part which is required for the development of the required system. Various
drawbacks and issues of enterprises information architecture has been described along with
possible strategies. In the end various challenges are mitigation techniques has been described
in details.

Introduction
EIA stands for Enterprise information Architecture is considered to be an essential part
of enterprise architecture. It is designed in such a way that is can provide a framework for
sharing of data in various departments of a firm by making use of cost effective techniques
(Adenuga, Kekwaletswe and Coleman, 2015). The information system of EIA is designed in such
a way that it can take care of various issues of privacy and security which contains right kind of
information. At present various government bodies round the globe are addressing issues due
to transparency, accountability of the citizen, business and community (Adler-Milstein, Bates
and Jha, 2013). This particular report deals with EIA RA is mainly focused for developing
Electronic health record system which can easily help the various government and citizen.
In the coming pages of the report an idea has been provided regarding EIA RA
(Enterprise
Information Architecture Reference Architecture). This particular not only works in systematic
way but it is also associated with various kinds of true methods and pattern which can be used
for design of information system. A conceptual architecture, logical architecture, relationship
and interaction diagram of various component has been provided. After that an operation
model, challenges, possible strategies for overcoming problem along with recommendation has
been provided.
Enterprise Information Architecture Reference Architecture for EHR system
The benefits of EIA RA (Enterprise Information Architecture Reference Architecture)
used for development of record related to electronic health are:
Integration of various enterprise: The ultimate goal of electronic health record system
can be easily achieved by the help of EIA RA. In this architecture various components of
enterprise are checked or ensured (Bender and Sartipi, 2013). Integration of various approaches
in done at various levels. The first layer is all about interconnection of various machines and
devices. The second layer is all about business integration which comprises of controlling of
business function and various processes associated with it.
Data domains of enterprises – The approach made by EIA RA is considered to be very
helpful for providing accurate kind of response by making use of single source and providing
accurate information through a single source and accurate kind of information to the eHealth
department of the organization (Da Xu, 2014). Various kinds of services like metadata services,
operational data and lastly content data is considered to be unstructured to the single central
system by making use of single approach related to domain of data. Integration helps in achieve
central kind of services along with management of enterprise.
