• Data from multiple heterogeneous data
sources and is used for analytical reporting
and decision making. Data Warehouse is a
central place where data is stored from
different data sources and applications.

6. OLTP vs OLAP
• ETL & Reporting Tools
An ETL tool extracts the data from all these
heterogeneous data sources, transforms the
data (like applying calculations, joining fields,
keys, removing incorrect data fields, etc.), and
loads it into a Data Warehouse.

8. The data mart is a subset of the data
warehouse and is usually oriented to a specific
business line or team. Whereas data
warehouses have an enterprise-wide depth,
the information in data marts pertains to a
single department. In some deployments,
each department or business unit is
considered the owner of its data mart
including all the hardware, software and data

Data Visualization Tools available in the market.

which the questions are asked. Parameter
values provide the answers to the questions. If
you include reports from different packages in
an interactive dashboard that uses global
filters, ensure that you use the same
parameter name for the prompt in all the
reports.
