Data Warehouse is collection of data from different operational systems in to one place.we can read,write,modfy the data as per requirement similar like the database.but main difference between database and datawarehouse is that we use data warehouse for decision support and analysis purpose.
Number of the ETL tools are available for the data warehouse like
1.Informatica
2.Data Stage
3.Abintio
as reetasharma108 has defined datawarehoue.that is the simplest and great way to understand.and also tools described are most appropriate.
at last,it completely depends upon u ,how conveniently u take up the tool.so go ahed ....great luck.....!!!!!
