Online patient information system the difficulties being faced by the patients while going for the check-up and tests to the hospital or medical centers despite of their medical conditions to make their life easier, they can check their updated medical status and billing accounts through the internet. Data flow diagram is a graphical representation of the flow of data through an information system it is one of the most commonly used systems-modeling tools, particularly in the operational system in which functions of the system are the most important and more complex than the data that the system manipulates. Information system analysis study play noun, description (eg patient information) what is a data store - a collection of data that is stored in some way - data flowing out is retrieved from the data store text-based process descriptions provide more information about the process than the dfd alone.

The system has sent out an invoice data flow, a delivery note data flow and goods ('goods' is not information it is shown as a double-headed arrow because it is a physical or resource data flow) payment comes in - ie a payment data flow is received, and a receipt data flow goes out to the customer. After tasks within a system are identified, it is necessary to expand this information into a data flow diagram (dfd) dfds are used to track the flow of data through an entire system the dfd answers the question, “now that the basic processes are defined, what data is needed for the processes to be carried out. Thus the patient management information system in this study ideally consists of integrated approach to maintain patient related administrative and clinical data considering the continuum of care dependent on the services provided4 related case study pioneering secure on line patient record management and collaboration between doctors clinical.

The patient record is the principal repository for information concerning a patient's health care it affects, in some way, virtually everyone associated with providing, receiving, or reimbursing health care services despite the many technological advances in health care over the past few decades.

Patient management system data flow diagram is often used as a preliminary step to create an overview of the patient without going into great detail, which can later be elaboratedit normally consists of overall application dataflow and processes of the patient process. The data flow diagram (dfd) is a graphical representation of the flow of data through an information system it enables you to represent the processes in your information system from the viewpoint of data the dfd lets you visualize how the system operates, what the system accomplishes and how it will be implemented, when it is refined with further specification.
