EHR SYSTEM USING EIA RA
Executive Summary
The purpose of the report is to propose Enterprise Information Architecture Reference
Architecture approach for development of electronic health record system through various
templates. The templates of Enterprise Information Architecture Reference Architecture consists
of different diagrams to illustrate the development of the overall project from starting phase to
closing phase. The diagram are provided this report to describe the detailed aspect of electronic
health record system. The advantages and limitations are provided in this report to understand
the enterprise architecture more briefly. The report finally concludes possible strategies that
should be adopted to mitigate the limitations of Enterprise Information Architecture Reference
Architecture approach for development of electronic health record system.

EHR SYSTEM USING EIA RA
Introduction
The management and maintenance of health information technology has been legislated
and proposed by United States Government. The health information technology is electronic
health record system that is proposed to be managed and maintained by health providers,
customers and patients. The facilitation of data integration and sharing will be achieved by the
electronic health record system proposed by the Government. United States Government requires
brief description and analysis of Enterprise Information Architecture Reference Architecture, a
framework that provides different templates as a design for developing any system or project.
Enterprise Information Architecture Reference Architecture helps in providing information
centric design for electronic health record system in this report. The architecture provides
different templates that are used in a systematic way of processes which has assumptions that the
processes are true and also tried methods. Enterprise Information Architecture Reference
Architecture provides benefits to organizations to design a system that helps to manage and
maintain a system from its initial phase to closing phase. The purpose of this report is to provide
an analysis of electronic health record system through approach of Enterprise Information
Architecture Reference Architecture templates along with its benefits and issues/challenges.
The structure of this report is Enterprise Information Architecture Reference Architecture
templates consisting of conceptual architecture, logical architecture, component relationship
diagram, component interaction diagram and operational model diagram. The benefits and
issues/challenges are also provided in this report with reference to Enterprise Information
Architecture Reference Architecture.
Enterprise Information Architecture Reference Architecture
Enterprise Information Architecture Reference Architecture provide following benefits
for designing and development of electronic health record system.
 Integration- Enterprise Information Architecture Reference Architecture helps to achieve
goals and objectives of electronic health record system. The interaction is enabled and
ensured between the component and entities of enterprises. The integration approach is
achieved differently at all levels of enterprise. The levels of integration are application
level, business level and physical level.
 Interoperability- The information in the form of conflicting and distributed databases, in
different locations are stored. The two information systems in interoperability approach
are characterized by each other’s functionality two improve the understanding between
them. The interaction among various information systems are facilitated by the approach
of this architecture. The benefits provided are at three levels and they are services, data
and procedures.
 Data domains- The accurate response via a particular individual source is provided in this
architecture where the correct information at a particular give time is provided to
electronic health record system. The data domains comprising of unstructured operational
data, content data, master data and meta-data, which are central system is provided
benefits from data domain approach. The enterprise management and integration of
central services in enterprise is achieved by integration.
 Interaction of information system- The operational and functional benefits are provided
to electronic health record by the approach of enterprise architecture (Charter and
Tischner 2017). This benefit provides to accomplish the respective tasks and services of
