Introduction to Information Systems and Informatics
What is Information Technology?
Study, design, development, implementation, support or management of a computer-based information systems, particularly software applications and computer hardware.
Prof. Carlos Ortiz - (2009)
What is Information Systems?
Information System is a combination of people, hardware, software, communication devices, network and data resources that processes data and information for a specific purpose including research, analysis and decision making.

Origins of the Term: Informatics
informatics- informa-tiks.[Russ. “Informatika”, French. “Informatique”]-OED.
1967 – “Informatics” is the discipline of science which investigates the structure and properties (not specific content) of scientific information, as well regularities of scientific information activity, its theory, history and organization”- OED.
1977 – “Informatics” change to “Medical Informatics” refers to the application of computer technology to all fields of medicine, medical care, medical research and medical teaching”- Collen, 1977.
1990- “Medical (Health) Informatics” is the scientific field that deals with biomedical and clinical information, data and knowledge, storage, retrieval, analysis and optimal use for problem-solving and decision-making”- Shortliffe and Blois, 1990.

What is Informatics?
Informatics is the science of information, the practice of information processing, and the engineering of information systems. Informatics studies the design, structure, behavior, and interactions of natural and artificial systems that store, process, access and communicate information (Example: Databases).
