   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.
