CHAPTER - 1 INTRODUCTION The application of information technology to healthcare has become increasingly important in many countries in the recent years. As on several applications has been ruminate in electronic healthcare (e-health), e.g., electronic health records, accounting and billing, medical research, and trading intellectual property .In particular Personal Health Records(PHRs) are believed to abate costs in healthcare and to improve personal health management in general. Healthcare organizations also must comply with multiple standards and regulations regarding patient data privacy, including those issued by the Joint Commission, the Health Insurance Portability and Accountability Act (HIPAA), and individual states.

Be independent of particular programming languages and development process. 4. Provide a formal basis for understanding the modelling language. 5. Encourage the growth of OO tools market. 6. Support higher level development concepts such as collaborations, frameworks, patterns and fundamentals. 7. Integrate best practices. 5.3 CLASS DIAGRAM: In software engineering, a class diagram in the Unified modelling Language (UML) is a type of static structure diagram that describes the structure of a system by showing the system's classes, their attributes, operations (or methods), and the relationships among the classes. It explains which class contains information. 5.4 USE CASE DIAGRAM: A use case diagram in the Unified Modeling Language (UML) is a type of behavioral diagram defined by and created from a Use-case analysis. Its purpose is to present a graphical overview of the functionality provided by a system in terms of actors, their goals (represented as use cases), and any dependencies between those use cases. The main purpose of a use case diagram is to show what system functions are performed for which actor. Roles of the actors in the system can be depicted. PHR USE CASE
