Architecture in based on a distributed approach and on the utilization of standard software products complying with the industrial and market standards must be utilized.(such as :UNIX operating systems, MS-Windows, local area network based on Ethernet and TCP/IP protocols, relational database management systems based on SQL language or Oracle database, C programming language) Aim of the Hospital Information System

As an area of medical informatics the aim of an hospital information system is to achieve the best possible support of patient care and outcome and administration by presenting data where needed and acquiring data when generated with networked electronic data processing.
