Data warehousing is a very mature, well-defined, and structured application of BI. Extract, transform, and load ETL processes are created that copy, clean, and load data from source systems into the data warehouse.
A data warehouse implementation often focuses on business processes that generate data. Once in the DW this data can be easily consumed by many other applications and tools all with consistent results.
The benefits of Data Warehouses are: Easier and more efficient query writing Reduced resource contention for operational systems Ability to easily query across data from multiple source systems Ability to easily query point-in-time snapshots of historical data Rigid data quality processes that ensure consistent, trustworthy data The trade off of a Data Warehouse is that the benefits of performance, convenience, and consistency come at the cost of up-front effort of design and implementation.
DWs are evolving databases. Data Warehouses are undeniably essential to any medium-to-large-scale BI ecosystem, but can be cost- or time-prohibitive for an organization just beginning to dip their toe in the BI waters.Data Warehouse Tutorial For Beginners - Data Warehouse Concepts - Data Warehousing - Edureka

Once every slicing and dicing of the data is done along with applied business rules, this data is ready for loading into the target tables.
This process is called Loading.

One line difference between Data Warehouse and Business Intelligence: Data Warehousing helps you store the data while business intelligence helps you to control the data for decision making, forecasting etc.
Data warehousing using ETL jobs, will store data in a meaningful form.
