Where should the ETL be ?
As I understand in organisational IT architecture there are 3 tiers.
1st tier(Data storage layer) : All the databases .
2nd tier(Business Tier ): All the middleware applications that include ETLs, messaging middleware , object oriented middleware etc
3rd tier(Client layer/Presentation layer) : Front end applications .
My question is why should ETL remain in the second tier instead of the first tier .
