predict future trends and behaviors, allowing businesses to
make proactive, knowledge-driven decisions. This is also
known as data surfing.

business rules, semantics, and definitions. A Dependent
Data Mart reads meta data from a central meta data
repository to define local meta data. This ensures that
all components of the architecture are linked via common

- Desktop Applications
- Query and analysis tools that access the source database or data warehouse across a network using an appropriate database interface. An application that manages the human interface for data producers and information consumers.
- A dimension is a structural attribute of a cube that is a
list of members, all of which are of a similar type in the
user's perception of the data. For example, all months,
quarters, years, etc., make up a time dimension; likewise
all cities, regions, countries, etc., make up a geography
dimension. A dimension acts as an index for identifying
values within a multi-dimensional array. If one member of
the dimension is selected, then the remaining dimensions in
which a range of members (or all members) are selected
defines a sub-cube. If all but two dimensions have a single
member selected, the remaining two dimensions define a
spreadsheet (or a "slice" or a "page"). If all dimensions
have a single member selected, then a single cell is
defined. Dimensions offer a very concise, intuitive way of
organizing and selecting data for retrieval, exploration
