Data warehouses are mainly used for our analyzing. Normally it is used for Top N Analysis of our company data.

Time Variant
Want to introduce new trend in your product then need to analyze large amount of data. This type totally helps us to introduce new tricks in our business.
Nonvolatile
Once data’s enter into the warehouse, then it should not be changed. Mainly data warehousing concepts use to analyze what has occurred.
Integrated
Integrated is almost equal to subject oriented characteristics. Put data in consistent format which we got from different sources.
Need to trouble shoot the naming conflicts in this process.
