The availability of such information enables a rapid reaction when necessary as well as sustained decision making based on processing of the massive accumulated data.
Extensive networking infrastructure supports the growing move to cloud computing, with the information-system resources shared among multiple companies, leading to utilization efficiencies and freedom in localization of the data centres.
Software-defined networking affords flexible control of telecommunications networks with algorithms that are responsive to real-time demands and resource availabilities. Many information systems are primarily delivery vehicles for data stored in databases. A database is a collection of interrelated data organized so that individual records or groups of records can be retrieved to satisfy various criteria. Typical examples of databases include employee records and product catalogs.
Databases support the operations and management functions of an enterprise. Data warehouses contain the archival data, collected over time, that can be mined for information in order to develop and market new products, serve the existing customers better, or reach out to potential new customers. Anyone who has ever purchased something with a credit card—in person, by mail order, or over the Web—is included within such data collections.
Big data enables innovative business models. For example, a commercial firm collects the prices of goods by crowdsourcing collecting from numerous independent individuals via smartphones around the world. The aggregated data supplies early information on price movements, enabling more responsive decision making than was previously possible.
The processing of textual data—such as reviews and opinions articulated by individuals on social networks, blogs, and discussion boards—permits automated sentiment analysis for marketing, competitive intelligence, new product development, and other decision-making purposes.
Qualified people are a vital component of any information system. Technical personnel include development and operations managers, business analysts, systems analysts and designers, database administrators, programmers, computer security specialists, and computer operators. In addition, all workers in an organization must be trained to utilize the capabilities of information systems as fully as possible.
Billions of people around the world are learning about information systems as they use the Web. Procedures for using, operating, and maintaining an information system are part of its documentation.
For example, procedures need to be established to run a payroll program, including when to run it, who is authorized to run it, and who has access to the output. In the autonomous computing initiative, data centres are increasingly run automatically, with the procedures embedded in the software that controls those centres.
Information systems support operations, knowledge work, and management in organizations. The overall structure of organizational information systems is shown in the figure. Functional information systems that support a specific organizational function, such as marketing or production, have been supplanted in many cases by cross-functional systems built to support complete business processes, such as order processing or employee management.
The information-system categories described here may be implemented with a great variety of application programs. We welcome suggested improvements to any of our articles.

The paper suggests that while computer science finds the formative aspect, of shaping, structuring, processing, of central interest, and business and organizational fields find the economic and social aspects of central interest, the Information Systems field can find the lingual aspect of central interest, while making links with the aspects of the neighbouring disciplines.
