1DATA AND SYSTEM INTEGRATION
Introduction:
This report mainly focuses on the Preparation of the e-Health system so as to maintain a
proper integration of the system and manage the data. The enterprise architecture has been
designed for the purpose of showing the link that exists between the different strategies of the
business as this has been integrated with the different applications of the business along with
the different layers of the infrastructure and also all the information. For the improvement of
the consistency and predictability of the project the information has been divided into various
layers and lastly information centric approach has been adopted for the purpose of developing
the EIA RA (Enterprise Information architecture reference architecture).
Enterprise Information Architecture Reference Architecture:
The different components that has been identified for the purpose of development of the
EIA RA includes the following:
 IT strategy
 IT infrastructure
 It architecture
 Business processes
 Business Information
 Business drivers
External applications:
This applications are mainly used for the purpose of managing the different types of
services which the individuals using the information system get which is followed by responding
according to the query of the users which is mainly regarding the health related information of
a patient. The identified goal of the e-health is the entire health related information of the
patients inside the information system. The external applications mainly includes the data
providers, platforms and the supply chain. This applications have a great influence over the
architecture of the information system. In case of absence of the external applications might
lead to different types of error so it is very much necessary to maintain this applications in
order to increase the efficiency and reduce the time needed for response.
Management of the Information:
There exists different types of data services and for the development of a general
framework there is a need of different standards, technology and users. The general framework
mainly consists of the:
 Master data service
 Data service
 Meta data service
 Content service
 Analytic service
Integration of the Data:
This is very much important as this helps in increasing the accuracy of the entire system.
Along with this there is a need of integration of the data for the purpose of using the data with

2DATA AND SYSTEM INTEGRATION
the same meaning and also for the purpose of using it in the different sources. All this data
needs to be integrated with the data sources as well as the different units of the business.
Lastly, all this integration would greatly help in the making of the decisions by the teams by
providing a combined view of all the information.
Program Application:
Different types of problem has been identified in the standalone system and the
functionality of the information system can also be increased by understanding the
Interoperability. Along with this reduction of the various types of complexities should also be
done and for doing this there exists different types of applications can be used.
Services related to security and Privacy:
The Information system consists of different data stored in it and all this data need to be
secured form any types of unauthorized access. One of the way by which this can be done is by
encryption of the data. Along with this accessing of the sensitive data in the database should
also be restricted in order to see that this data are not misused and the privacy of the patient is
maintained.

Logical over view of the new Model:
Fig 2: Logical Architecture
The main reason for including the delivery service is for the purpose of connecting the
end users and also consists of the external data service providers, user interface which are
collaborative in nature, and many more. The main use of the information channel includes the
representation of the different data blocks and eth storage of the data which is mainly
associated with recording the e-Health records. The enterprise information represents the
connection that exists between the services of the enterprise and the information services
which are mainly provided by the e-Health Information system.
The flow of the data mainly starts from the data collection from different sources. For
improving the efficiency data is to be collected from the laboratories and is to be added to the
information system. The collection of the data is to be done at single place and also a block
diagram is to be made in order to demonstrate the flow of data.
In this architecture the domain and the database are associated with acting as the
central component of the whole IS. This is to be managed in a proper way in order to
implement all the data services. Due to the fact that the system would be present in different
locations it is to be made sure that the design is made in such a way that accuracy of the system
is increased.
The EIA RA has several benefits and this happens due to the reason that facilitation of
the common understandings is done which is mainly required by the business lines while
application of various models. This models are generally created with a wide point of view. The
implementation of the corporate data model it is possible to analyze the data framework which

4DATA AND SYSTEM INTEGRATION
is existing and this is mainly used for the reengineering purpose in order to maintain the
integration of the different sets of data along with this the implementation of the new model
would be helping in the mapping and integration of the data with the data models of different
database.
Integration of the Enterprise Information:
This is mainly done by the software which is mainly associated with combining of the
different information and data from different sources. Associated with this is the recording of
the different health related information. The main use of the service is done for the purpose of
monitoring of the data which is followed by representation of those data and the services by
the information system. Integration of other applications of business like the ERP and many
more can be used for the purpose of managing the information of the patients and the staffs
which would be very much beneficial.
Integration of the Components:
Fig 3: Component Relation Diagram
Master Index: This is mainly used for the purpose of creating the interaction between
the government and the constituents and this mainly includes the information about the LAB
reports, billing, pharmacy and many more. This master index is also associated with acting as
the collaborative service along with acting as the main database for the healthcare providing
organizations in order to maintain the records of the patients and the accuracy of the data.
Along with this it also acts as the main component for the security and the privacy. All the
patients get their unique identification code which can be used for identifying them any time.
Interfaces:
Presentation should be done only after updating and integrating the data with the other
information which is very much helpful while responding to the various types of queries. It is

5DATA AND SYSTEM INTEGRATION
very much essential to look into the matter that the data is correct and the interfaces are acting
as the hub between various collaborative services. There are various way in which the problems
related to integration can be mitigated and this includes the enrichment of the data,
development of agile frameworks and application of eth new innovative technologies.
Management of the Information and Integration:
Various type of difficulties are there in the healthcare industry which needs to be
addressed. In the e-Health service there is an essential need of including the various hospitals
so as to address any type of disparities present in healthcare sector. The quality of the service
can be greatly increased by including eth various organizations. Along with the challenges there
are also various types of opportunities. One such opportunity includes the reduction of the
errors and increase of flexibility. There is a need of improving the way in which the data is
collected along with enhancing the storage options so as to create a platform for the purpose of
sharing the information.
Besides all this there exists dissimilarities in the systems nature and the entities. They are
analyzed in order to develop the logical architecture of the system. Along with this evalution of
the technical functionalities and the functional services are done in order to establish the
relationship between the presentation layer and the application layer. The main reason for the
development of the component diagram is for the purpose of delivering the functionality of the
logic model.
Different types of tools are used for the purpose of analyzing the structured as well as
the unstructured data. Along with this the tools also helps in the identification of the different
patterns and the items which has been searched. Relational database is used for the purpose of
managing the structured data where clear and defined data types are used. Data hadoop is
mainly used for the purpose of handling the unstructured data and this is done mainly because
it is designed for the purpose of supporting the big data.
Generally the representation of the structured as well as the unstructured data is done
by making use of the operational model as it is associated with taking the components form the
component model and then distributing it across various locations. There are more than one
component in the node and this are known as the deployment units. The design of the
component model is to be done in such a way that there is continuous availability and reliance.
The management data is greatly challenged due to sensitive data. In order to maintain
the privacy the VPN technology can be used as it is associated with providing a secure channel
for communication. User authentication is present along with this so as provide the users with
authentic access to the data present at different locations. VPN is greatly affected by the
internets speed. Along with this there also exists various protocols which are very much helpful
in establishing the connection. The use of gateway helps in identifying the user and also helps
the user in reaching the internal resources located at different locations.
Integration is generally used for the purpose of combining the data which is generated
from different sources rather than storing the information by making use of different new
technologies. It is very much important to combine the different subsystems in order to have a
unified view of the whole system. Development of data warehouse and migration of the data

6DATA AND SYSTEM INTEGRATION
from different sources is very much important. The hardware can also be improved so as to
make the migration of data much more easy and merging the new data with the existing one so
as to create a common view.
Conclusion:
The report helps in concluding to the fact that there is a need of analysis so as to
develop the new enterprise architecture. This ERA RA template has been used for the
purpose of designing of the architecture diagram and identification of eth various
capabilities in order to create the block diagram and how the e-Health service is used.
And from the architectural diagram the overview of the conceptual level is analyzed and
after this it has been broken down into different logical levels which mainly consists of
the logical architecture and the model of the components. By making use of the
operational model different nodes have been identified which are located in different
locations along with the various data connections. The information of eth enterprise is
gathered in order to develop the reference architecture.
