According to Solomon Negash and Paul Gray, business intelligence (BI) can be defined as systems that combine: •
Data gathering •
Data storage •
Knowledge management with analysis to evaluate complex corporate and competitive information for presentation to planners and decision makers, with the objective of improving the timeliness and the quality of the input to the decision process." According to
Forrester Research, business intelligence is "a set of methodologies, processes, architectures, and technologies that transform raw data into meaningful and useful information used to enable more effective strategic, tactical, and operational insights and decision-making." Under this definition, business intelligence encompasses
information management (
data integration,
data quality, data warehousing, master-data management, text- and content-analytics, et al.). Therefore, Forrester refers to
data preparation and
data usage as two separate but closely linked segments of the business-intelligence architectural stack. Some elements of business intelligence are: • Multidimensional
aggregation and allocation •
Denormalization, tagging, and standardization • Realtime reporting with analytical alert • A method of interfacing with
unstructured data sources • Group consolidation, budgeting, and
rolling forecasts •
Statistical inference and probabilistic simulation •
Key performance indicators optimization •
Version control and process management • Open item management Forrester distinguishes this from the
business-intelligence market, which is "just the top layers of the BI architectural stack, such as
reporting, analytics, and dashboards."
Compared with competitive intelligence Though the term business intelligence is sometimes a synonym for
competitive intelligence (because they both support
decision making), BI uses technologies, processes, and applications to analyze mostly internal, structured data and business processes while competitive intelligence gathers, analyzes, and disseminates information with a topical focus on company competitors. If understood broadly, competitive intelligence can be considered as a subset of business intelligence.
Compared with business analytics Business intelligence and
business analytics are sometimes used interchangeably, but there are alternate definitions.
Thomas Davenport, professor of information technology and management at
Babson College argues that business intelligence should be divided into
querying, reporting,
Online analytical processing (OLAP), an "alerts" tool, and business analytics. In this definition, business analytics is the subset of BI focusing on statistics, prediction, and optimization, rather than the reporting functionality. ==Unstructured data==
