Most companies today are finding it difficult to compete without some kind of integrated data source to supply the information needed for
business analysis.
A data warehouse supplies this integrated data source in an easy to use manner. Business managers and analysts can design and run
their own queries and reports without having to rely on other support staff.
A data warehouse will most likely identify existing data quality issues. It is important that the data warehouse and operational
system teams work together to either clean this data or make other arrangements in the presentation of this data.
