Hi,

 

Greetings Guys !! I am wondering and kind of lost with giant SAP newly introduced database SAP HANA. I have been informed that HANA is developed for fast query processing mainly.The older method of query processing involves lot of time ,i.e . the request should go to database and will retrieve information . If HANA have shown IMDB ( In- Memory database ) technology , Dataware house concept also solves waiting time of query processing .

 

Could some one explain me why HANA is introduced if Dateware house concept was already born ??
