Business intelligence is an
integrated framework of an information system that provides the
business with a complete view of business activities and
operations. Data warehousing is frequently used for decision
support within a company or organization and provides the
organization with organized, updated and coordinated data that
provides a view of relationships between information obtained from
different sections of the organization.
data warehousing design involves generating, manipulating and
mapping models with business intelligence focus on an overall view
through one front regardless of data storage style, number and
locations. The models are physical, logical, and conceptual
representations of the business data and end-user information
a data warehouse requires the mapping of data between source to
target models, capturing the details of the transformation in the
data warehouse by utilization of tools that support these
activities which are known as data warehouse mapping and
transformation design tools.
definition a "Data Warehouse" is a very massive database
that frequently provides access to all of an organization's data
(information). Data could be distributed over several databases on
multiple computers and may contain information from numerous
sources in different formats and varieties. The user data access
to data source (regardless of location, format, type or hardware
etc) should be transparent.
warehouses also contain information about how the warehouse is
structured (it has data about the data stored in it) and
organized, where the information is and the relations between the

this task, it is best to make some form of mapping tool or to
find an off the shelf one to fetch, transfer and load the data
from the various applications. Such tools identify the
information contained in data source systems and identify where
that information needs to be loaded into the data warehouse.
