Information system: an
integrated set of components for collecting, storing, and
processing data and for providing information, knowledge, and digital
products.
“Information systems are combinations of hardware, software, and
telecommunications networks that people build and use to collect, create, and
distribute useful data, typically in organizational settings.”
Business firms and other organizations rely on information systems to carry out
and manage their operations, interact with their customers and suppliers, and
compete in the marketplace. Information systems are used to run inter-
organizational supply chains and electronic markets. For instance, corporations use
information systems to process financial accounts, to manage their human
resources, and to reach their potential customers with online promotions. Many
major companies are built entirely around information systems. These
include eBay, a largely auction marketplace; Amazon, an expanding electronic
mall and provider of cloud computing services; Alibaba, a business-to-business
e-marketplace; and Google, a search engine company that derives most of its
revenue from keyword advertising on internet searches.
Information systems Need in Banks:
The need of information was first realized in the banking industry. Being in the
service sector, banks needed to store information to better their services and gain a
competitive edge over their competitors. Basic services include the book keeping
records of the customers while the luxurious ones include the facility of an IVR
(Interactive Voice Recording) through which customers can get answers to their
F.A.Q’s. However, developing an information system needs huge investments,
responsibility of non-leakage of information (robustness of the system), and
various other security measures. Banks therefore need information at every stage
possible. The benefits of information are many. Today, decision making systems
are also used by banks for purposes of marketing newer loan schemes.
