This presentation is about information system. It starts with the definition of information systems, parts of information system and its various types. A pictorial representation of each type is also provided. It then moves on with an explanation about each type of information system beginning with transaction process system, its examples and sub-species. Following this is the office automation system and its subspecies, decision support system, Knowledge management system(with scenario representation),executive support system and the management information system. The concluding point will be a discussion on the security issues with each of these ty
