 Data sources
 The sources consist for the most part of data belonging to
operational systems, but may also include unstructured
documents, such as emails and data received from external
providers.
 Generally speaking, a major effort is required to unify and
integrate the different data sources.

 Data Warehouses and Data Marts
 Using extraction and transformation tools known as extract,
transform, load (ETL), the data originating from the
different sources are stored in databases intended to
support business intelligence analyses.
 These databases are usually referred to as data warehouses
and data mart.

 Business intelligence methodologies
 Data are finally extracted and used to feed mathematical
models and analysis methodologies intended to support
decision makers.
 In a business intelligence system, several decision support
applications may be implemented.
