amazon web services - What kind of data gets stored in data warehouses? -


looking @ services amazon redshift, meant storing petabytes of data. forms of data meant stored here? logs, raw data?

the question data warehouse not kind of information store in rather how store , inted use for. data organisation needs analyze , compare may put data warehouse.

define data warehouse difficult , you'll many definitions people ask. i've seen lots of different implementations , no 1 can data warehouse , not. there number of key points data warehouse should fulfill, namely should time variant (i.e. store datapoints on time) , should non-volatile (i.e. never update data in data warehouse, insert).

following these rules allow common data warehouse analysis, namely analyze data on time, e.g. compare seasons sales last season.

i'm not sure amazon redshift do, if data warehouse or not think more question of how use it.
