When reading a tag according to the data retrieved from it this agent performs the appropriate operations . if the tag belongs to a family doctor general practitioner it creates the proper physician agent or if the tag identifies a patient it displays its own medical records. This agent is used for the authentication of multi-agent system users. The update of the patient s electronic health records with information from HL7-compliant or non-HL7 servers is performed automatically at a particular time set to the Supervisor Agent. To achieve this task the Supervisor Agent extracts from the database the identification numbers of patients who have performed medical investigations outside the medical unit where they are registered and the list of server addresses of healthcare units where such medical examinations were performed. For each patient the Supervisor Agent creates an Integration Agent which receives as parameters his identification number and the list of non-HL7 servers corresponding to the medical units in question along with the names of the DB Agents which they will communicate with for getting the necessary information. The Integration Agent sends REQUEST messages containing the patient s identification number to the DB agents of the partner medical units and then waits for answers from those agents. Each of these DB agents is familiar with the login details to the database from which information about the patient has to be retrieved such as database type address user and password and the database structure. Thus based on the received identification number the DB agent will extract data from the database tables containing the results of medical examinations undergone by the patient and will send them to the Integration Agent that requested it. The Integration Agent will mark in the database that it received the
