Answer / lakshminarayana

intermediate area between source system and data warehouse.it is temporary schema/user.after completion of each session we have to delete the previous data from staging area(table) before going to load data into staging area.it is used mainly for the purpose of increase the performance of source system means we perform join condition it will take lot of time to execute because join perform on the total data of table.but staging area required particular condition data means it required small amount data not the total copy of source data.and it used for clean the data before loading.it is relational data base.no end user can't access the data and no transformation perform on the staging area.if the session will failure then we directly receive particular data from staging area.means we can decrease the burden on source by using staging area.
