What's A Data warehouse
Data Warehouse is a repository of integrated information, available for queries
and analysis. Data and information are extracted from heterogeneous sources as
they are generated....This makes it much easier and more efficient to run
queries over data that originally came from different sources.
Typical relational databases are designed for on-line transactional processing
(OLTP) and do not meet the requirements for effective on-line analytical
processing (OLAP). As a result, data warehouses are designed differently than
traditional relational databases.
