Abstract
In today’s information and communication age, there is a constant reference to information systems and management of information systems. In the digital age data, storage and retrieval are done through various systems and interfaces. An information system, therefore, can be defined as set of coordinated network of components which act together towards producing, distributing and or processing information. An important factor of computer based information system is precision, which may not apply to other types of systems. In a system, network of components works towards a single objective, if there is lack of co-ordination among components, it leads to counterproductive results. A system may have following features: Adaptability: some systems are adaptive to the exterior environment, while some systems are non-adaptive to the external environment. For example, anti-lock braking system in car reacts depending on the road conditions, whereas the music system in the car is independent of other happening with the car. Limitation: every system has pre-defined limits or boundaries within which it operates. This limits or boundaries can be defined by law or current state of technology. Common definition of information is data. However, data is no true information. Data gets its meaning and significance if only it is information. Information is represented with data, symbols and letters. Information has following properties: Objective: One of the key properties of information is its objectiveness. Objective information is a key component of any modern scientific research. Subjective: Set of information which is useful to science may be abstract or irrelevant for others. Therefore, information is subjective also and Temporary: Information is temporary with every update in the database.
