...INTRODUCTION An information system is a collection of hardware, software, data, people and procedures that are designed to generate information that supports the day-to-day, short-range, and long-range activities of users in an organization. The history of information systems coincides with the history of computer science that began long before the modern discipline of computer science emerged in the twentieth century. Regarding the circulation of information and ideas, numerous legacy information systems still exist today that are continuously updated to promote ethnographic approaches, to ensure data integrity, and to improve the social effectiveness & efficiency of the whole process. In general, information systems are focused upon processing information within organizations, especially within business enterprises, and sharing the benefits with modern society. The 'classic' view of Information system of the 1980’s was pyramid of systems that reflected the hierarchy of the organization, usually transaction processing systems at the bottom of the pyramid, followed by management information systems, decision support systems and ending with executive information systems at the top. Although the pyramid model remains useful, since it was first formulated a number of new technologies have been developed and new categories of information systems have emerged, some of which no longer fit easily into the original pyramid model. Some examples of such systems are: *......

...TYPES OF INFORMATION SYSTEMS An information system is a collection of hardware, software, data, people and procedures that are designed to generate information that supports the day-to-day, short-range, and long-range activities of users in an organization. Information systems generally are classified into five categories: office information systems, transaction processing systems, management information systems, decision support systems, and expert systems. The following sections present each of these information systems. 1. Office Information Systems An office information system, or OIS (pronounced oh-eye-ess), is an information system that uses hardware, software and networks to enhance work flow and facilitate communications among employees. Win an office information system, also described as office automation; employees perform tasks electronically using computers and other electronic devices, instead of manually. With an office information system, for example, a registration department might post the class schedule on the Internet and e-mail students when the schedule is updated. In a manual system, the registration department would photocopy the schedule and mail it to each student’s house. An office information system supports a range of business office activities such as creating and distributing graphics and/or documents, sending messages, scheduling, and accounting. All levels of users from executive management to nonmanagement employees utilize...

...Reaction Paper Submitted by: Santos, AB Information Systems and Developing Countries: Failure, Success, and Local Improvisations Richard Heeks Institute for Development Policy and Management, University of Manchester, Manchester, United Kingdom Information system is the lifeblood of communications. It is a network defining linkages among various individuals, groups, and entities. Information system operates in ever-changing medium – land, air, water, light, electromagnetic waves, and cyberspace. It has only one objective: establishment of relationship. There is no relationship if there is no communication. With communication becoming more and more complex every day, information system is following suit. Information system, however, like standard of living, is unique in any peculiar way for a particular place where it functions. And it is this observation and situation that the author of this article, Mr. Richard Heeks, is earnestly trying to impart. Not being biased for industrialized countries, Mr. Heeks discusses information systems as applied in the developing countries although he does not dwell on some phenomenon common to both industrialized and developing countries alike. The bulk of the discussion is about what he meant in his title, i.e., failure, success, and local improvisation of information system. Seemingly hidden are at least two things perhaps because it is considered fait accompli - resistance to change and staff rivalry. Posed...

Types of Information Systems and How They Are Used Effectively

...XACC/210C The information systems that are used in the office I work at include an office information system, and a transaction processing system. Everything in my office is performed electronically. I submit all claim forms through EDI on a daily basis. EDI (electronic data interchange) is used for electronic exchange of text, graphics, audio and video. Submitting my claim forms this way creates less waste, as with the paper and mail format. It also saves money. The hardware that is used includes my computer, copy machine, and a facsimile. All of these things used make the process a lot easier. Rather than having to send and receive everything through snail mail. When submitting through an EDI, I can receive my payments back within two weeks. If I was to send through the mail, I would have to wait up to 6 weeks to receive something back from an insurance company. A transaction processing system is another information system that I use on a daily basis. I record all patient payments all with the click of a button. I also enter in patient updates and new patient data into this system. I can also remove any unwanted or unnecessary information. All transaction data is saved into this system. So at the end of the day all I have to do is print a daily payment/transaction report, and make sure I balance out at the end of the day. I suppose that this all would be included as an online transaction processing system? I feel that with the everyday use of doing......

...Like other networks, the Intranet is mainly used to share data, information, resources, company programs, software applications. Intranet improves the data sharing capability and overall knowledge base of the company’s employees (Difference between Intranet and Extranet). Extranet, is an internal network that can be accessed externally. The extranet is the extension of the company’s intranet where People from outside the company can have a limited access to the company’s internal network for business related purposes. This access is usually granted to the organization’s partners, vendors and potential customers etc (Difference between Intranet and Extranet). Security-wise, Intranets are a lot more secure due to the limited interface with the Internet. Extranets are made less secure not only by the use of the Internet as a medium but also by the fact that the administrators of the Intranet have no control over the networks that connect to the Extranet. When sensitive information is being transmitted on the Intranet, all parties need to take all security precautions to prevent spying and other similar activities (Difference between Intranet and Extranet). The main difference between an intranet and an extranet is that the intranet is the network that is limited for use on the organizations computers, whereas the extranet is an extension of the company’s intranet. The extranet make available some of the information of the intranet to people not directly connected to the......

...Types of Information Systems Bailey, Sarah XACC/210 January 17, 2016 Vincent, Richard Types of Information Systems Transaction Processing Systems (TPS) According to “McDonald’s Information Systems” (n.d.), The first transaction happens when two people make an exchange, and collecting data about it is called transaction processing, so transaction processing is collecting, storing, modifying, and retrieving the transactions of an organization. Transaction system is important to answer routine questions, and it helps to conduct business such as payroll, employee record keeping or paying an employee.
