ODS : Operational Data Source. IT is just like OLTP. It will
maintain day to day transactions. In Some Organizations will
consider this as Data Back up or Data Recovery. When we are
loading the data we will take ODS tables as Source tables.
IT is Fully Normalized. Since it is normalized retrieving
the data will take time.Depend on the Organization they will
refresh the ODS.
