Chapter Summary
|
To enable a company to achieve its objectives, it is essential that the
management has a clear understanding of the kind of information that needs
to be collected, stored, and analyzed. This information should be consistent
with the requirement of the organizational level at which it is targeted.
Information systems that process data generated from the occurrence of
business transactions are called transaction processing systems.
Information systems in many large organizations are combinations of various
functional information systems like marketing information systems,
manufacturing information systems, human resource information systems,
accounting information systems, and financial information systems.
An MIS can be defined as an integrated, user-machine system that provides
information to support the managerial, operational, and decision-making
functions in an organization. |

The characteristics of an MIS are that it is management-oriented,
management-directed, an integrated system, enables maintenance of a common
database, and is flexible. The functions of an MIS are data collection, data
storage, and information presentation.
DSSs are used to help in managerial decision making. A DSS is flexible,
based on simple models, and uses a database. An EIS aims at providing timely
information to the top management. For the successful implementation of the
EIS, a consensus between a senior management person and a project leader is
essential. OLAP helps in multidimensional analysis and provides timely
information. A well-designed OLAP can help in efficient data management.
Information systems can be used by businesses to achieve strategic
advantage. Improving business processes, reengineering of business
processes, agile competition, creating virtual companies, and knowledge
management are some of the advantages of using information systems in
business.
