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
[...] DSS has Greater analytical power than other systems, incorporate modelling tools, aggregation and analysis tools, and support what-if scenarios Must provide user-friendly, interactive tools Knowledge Management system Knowledge management is an integrated, systematic process for identifying, collecting, storing, retrieving, and transforming Information and Knowledge assets (including previously unarticulated expertise and experience held by individuals) into Knowledge that is readily accessible in order to improve the performance of the organisation. Examples Knowledge work professional systems Automotive engineers use computer-aided engineering (CAE) software together with “virtual reality” systems to design and test new models for fuel efficiency, handling, and passenger protection before producing prototypes, and later they use CAE in the design and analysis of physical tests.

Interrelationship and interdependencies between IS Security Issue Bibliography Definition The term information system (or computer-based information system) refers to the specific application software that is used to store data records in a computer system and automates some of the information-processing activities of the organization. Parts of information systems Input Output Processor Memory Types Transaction processing systems Decision support systems Knowledge management systems or knowledge work professional support system Executive Support system Management information systems Office automation system Transaction Process System Transaction Process System it is a type of information system that collects, stores, modifies and retrieves transaction of an organization.

[...] Management Information Systems A management information system is mainly concerned with internal sources of information. MIS usually take data from the transaction processing systems (see below) and summarize it into a series of management reports. Transactions recorded in a TPS are analyzed and reported by an MIS. They have large quantities of input data and they produce summary reports as output. Used by middle managers. An example is an annual budgeting system. MIS reports tend to be used by middle management and operational supervisors. [...]
[...] Security Issue Information systems security measures The first step in creating a secure information system is to identify threats. Once potential problems are known, the second step, establishing controls, can be taken. Finally, the third step consists of audits to discover any breach of security.

[...] Also known as an Executive Support System it provides executives information in a readily accessible, interactive format. Used by top level (strategic) management. They let the CEO of an organization tie in to all levels of the organization. They are very expensive to run and require extensive staff support to operate.
