A data warehouse (short DW) is a huge database. This data is used for reporting, decision making and forecasting.
A data mart is a subset created from a data warehouse, focussed on a specific area within the business (dependent data mart).
Working with data marts improves the performance of the system due to the smaller amount of data.
Analyses and forecasts can be adjusted to specific requirements more easlily.
