An information system can be a mainframe, mid-range or network computer concept that allows distributed processing for a group of users accessing the same software application. These systems provide management with control over their data, with various tools to extract data or view data structures and records. The role of an information system is to foster a data management environment that is robust and can be expanded according to an organizations’ strategic plan for information processing. An information system also satisfies diverse information needs in an organization.
With an increasingly competitive and expanding market, the amount of information needed daily by an organization is profound. Thus they have to establish a Marketing Information system. Upgrading the computer information system is not an option in this technology-driven era; it is a requirement. Companies that use an up-to-date information system to gather, assimilate, and evaluate internal as well as external information are gaining competitive advantage over other firms. Management is quicker to cater to customer’s needs and complaints. With the growth of communication networks, there are almost no barriers between the firm’s management, employees, customers and suppliers. Networked computing systems have made new modes of work possible.
A sophisticated computer information system enables companies to monitor employees, to keep managers and employees informed, to coordinate activities among divisions, or even to sell their products to customers via the internet. Moreover, in the era of information technology like this, information has become valuable organizational asset just like human resources and inventories.
I hope this has given you an insight into understanding Information Systems.
