Business Intelligence and Data Warehousing
Often BI applications use data gathered from a data warehouse or a data mart. However, not all data warehouses are used for business intelligence, nor do all business intelligence applications require a data warehouse.
To distinguish between the concepts of business intelligence and data warehouses, Forrester Research often defines business intelligence in one of two ways:
Using a broad definition: "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." When using this definition, business intelligence also includes technologies such as data integration, data quality, data warehousing, master data management, text and content analytics, and many others that the market sometimes lumps into the Information Management segment. Therefore, Forrester refers to data preparation and data usage as two separate, but closely linked segments of the business intelligence architectural stack.
Forrester defines the latter, narrower business intelligence market as, "...referring to just the top layers of the BI architectural stack such as reporting, analytics and dashboards."

Famous quotes containing the words business, intelligence and/or data:
“Dishonesty in government is the business of every citizen.... It is not enough to do your own job. There’s no particular virtue in that. Democracy isn’t a gift. It’s a responsibility.”
—Dalton Trumbo (1905–1976)
“If woman alone had suffered under these mistaken traditions [of women’s subordination], if she could have borne the evil by herself, it would have been less pitiful, but her brother man, in the laws he created and ignorantly worshipped, has suffered with her. He has lost her highest help; he has crippled the intelligence he needed; he has belittled the very source of his own being and dwarfed the image of his Maker.”
—Clara Barton (1821–1912)
“Mental health data from the 1950’s on middle-aged women showed them to be a particularly distressed group, vulnerable to depression and feelings of uselessness. This isn’t surprising. If society tells you that your main role is to be attractive to men and you are getting crow’s feet, and to be a mother to children and yours are leaving home, no wonder you are distressed.”
—Grace Baruch (20th century)
