Information system plays a role in every aspect of our lives. In fact, our world is full of lots of information. Information either from the school, from the government, hospital, etc. From your music play list to your mobile phone contents, from your saved computer games to the details in your facebook profile.
Like this, there is a lot of information and it all needs to be stored, categorized and organized for reference and other purposes. This huge amount of data is growing tremendously. So how then do we manage this massive increase in the data we store? We depend on information systems. It helps us create, store, control, access and find this information.
Information system is the combination of users, technology and processes to complete a given goal. It is a set of computer-based tools for collecting, processing and storing data. For businesses, in order to manage their operations, complete maketplace and negotiate with their customers, they rely on information system. Like for example, corporations who want to manage their workforce, process financial accounts and reach their potential customers, they too use information systems with targeted messages over the web.
Governments too use information systems to provide services to citizens, to manage the economy and to gather taxes. Electronic books, online services such as social networking and other digital goods are all provided by and operated by some kind of information system.
Information system is indeed a need. Meanwhile, we call the people who have an interest in information systems as stakeholders.
