一个系统是一组之间的相互关联和实体和它们的属性,形成一个整体。在正确地定义系统中,组件(大致可输入、处理、输出和反馈)结构在一起展示一个特定类型的行为影响系统行为的(Laudon & Laudon,2011)。系统中存在一个预定义的环境,它可能包含子系统,一起接受输入和交互产生转换后输出。
A system is a set of entities and the associations with each other and between their attributes so as to form a whole. In a properly defined system, components (broadly which can be input, processing, output and feedback) are structured together to demonstrate a particular type of behaviour which affects the system behaviour at large (Laudon & Laudon, 2011). A system exists in a predefined environment and it may contain sub-systems, which interact together to receive input and produce output after transformation.
Most of the systems (we will discuss organisation as a system) use information for its smooth operation. Accurate and timely information in an organisation is very critical for employees to perform task effectively. Organisations understand the importance of information flow and develop a system which enables providing information in an effective way. This helps employees in building more efficient internal processes. It also helps in assimilating various business functions and linking with customers and vendors in a better way. A computer based information system is more than just computers and software; it rather involves many other systems within from human activity systems to organisational systems and hardware and software systems (Alter, 1998). Computer based IS has become a very critical part of organisations. With advents in technology and increasing importance of information, IS has taken the foreground. An IS can be defined broadly as a set of interconnected components that assembles, manipulates and disseminates data and information and provides feedback to meet an objective. In organisation context, IS is more than computers; it is rather a nucleus which enables meaningful interaction of management, technology and organisation (Delone, 2003).
