A data warehouse is an integrated collection of data that can include seemingly unrelated information, no matter where it is stored in the company.
An enterprise data warehouse (EDW), sometimes referred to as a data warehouse (DW or DWH) in computing, is a system used for reporting and data analysis and is regarded as a key element of business intelligence.
data warehouse DWs serve as a central repository for combined data from a variety of sources.
They keep both recent and old data in a single location that is utilized to provide analytical reports for employees across the whole company.
The operational systems upload the data that is kept in the warehouse (such as marketing or sales).
Before being used in the data warehouse for reporting, the data may go via operational data storage and require data cleansing for extra activities to ensure data quality.
