Computer Based Information Systems

The information system I chose from chapter one is computer-based Information Systems (CBIS). Wikipedia defines CBIS as, “an IS using computer technology to carry out some or all of its planned tasks” (1). There are parts of this system including, hardware, software, databases, networks, and procedures. Types of these systems include transaction processing system, Management Information System, Decision Support Systems, and Office Automation Systems according to MBA Knowledge Base (2). I use these types of systems on a daily basis for my job. Digital systems are where information systems continue to go toward, all electronic. At my job, I have to input property information into a CBIS software database program called Mitchell Humphrey. That system keeps track, and organizes crucial information such as lot size, property owner, property value, and more for quick access later on. Hilton Hotel group describes the importance of hardware in a CBIS by stating, “...a fast, reliable connection to the Internet was the second most important factor” (textbook). Without internet hardware, CBIS would not exist. There must be a network in place using routers as hardware for the information systems to communicate. Network also be included with telecommunications. In a Transaction Processing System, hardware, and software must work together to process data such as sales information. California State University discusses the histories of the computer, information systems, and their histories (3). In 1955 IBM releases and sells the first commercial computer that is much larger and less efficient than anything today. in 1962 airlines start a reservation intranet information system to keep better track of the passengers, maintenance, and other commercial aviation data. In 1971, Intel released their first processor furthering the evolution of CBIS. In 1988 60% of workers used computers, and the first portable laptop is released. This all leads to the “dot-com” boom in the late 1990’s. With more people online than ever, CBSI was implemented in small and large businesses across the U.S. and the world. CBSI is used daily by millions of people. The importance of these systems cannot be stressed enough. From Transaction Processing Systems in stores to Decision Support Systems used by business professionals CBSI plays an intricate part in the function of those particular systems. CBSI allows data and information in databases to be accessed through the internet at businesses and more commonly today in the cloud.
