Object Oriented Analysis and Design

Notes
Electronic Data Interchange (EDI) networks. Thus, developers and systems integrators
have a simple guidebook for, say, labeling “penicillin” as an adverse-reaction drug in the
field “allergies,” so patient records in a hospital database and the Web browser in a
pharmacy both know where to store the data.
XML also works with existing Web standards. Hypertext Markup Language (HTML)
determines how data is displayed on screen. The data passes from the Web to a variety of
hardware that connects to the network via TCP/IP. XML labels incoming data so any
application knows how to handle it. Because XML can exchange data among different
computing platforms it helps solve the inter-operability problems of middleware. Getting
various back-end systems that use CORBA or COM components to work together.

The component technologies described in this article are being standardised through
various organisations in the US.
Conclusion

Thus, many “flavours” or interpretations of the standard exist today. The problems with
standards are that there are so many! This has led many healthcare IT professionals to
view standards with some skepticism. However, there is not a great deal of overlap
among these standards, and development tries to make use of the best features of existing
standards, rather than compete with them.
While it is true that the many standards activities within the healthcare arena are not
perfectly aligned, they are generally not competitive. Healthcare IT professionals are not
faced with a choice of standards, but a set of standards to use in different circumstances.
HL7 will continue to dominate in the host world, although CORBA could play a role,
particularly where the retention of data ownership rights is an issue. CORBAmed should
provide the standards for client-host computing, as CORBA middleware is robust and
proven in enterprise-scale applications.
DICOM should provide the model for observational reporting as well as the representation
for medical image data, particularly for primary diagnosis; ASTM on healthcare
applications standards; ASC X12 on billing standards and various organisations on coding
and vocabulary standards.
Users should insist that they continue to cooperate toward greater reuse and
inter-operability.

Healthcare IT can be run by those who have gained experience and success in non-healthcare
IT, where IT experts learned to use IT to support organisational goals. The future path to
management advancement in healthcare may be through enterprise IT.
Question
Discuss the use of CORBAmed in healthcare industry.

2.5 Summary

Object-oriented Analysis and Design (OOAD) is a software engineering approach that
models a system as a group of interacting objects.

Object-oriented Analysis (OOA) looks at the problem domain, with the aim of producing
a conceptual model of the information that exists in the area being analyzed.
Modeling is used frequently, during many of the phases of the software life cycle such as
analysis, design and implementation.
