As previously stated, data marts are far less costly than data warehouses. A typical
data mart costs less than $100,000, compared with $1 million or more for a data
warehouse. Also, data marts can be implemented more quickly often in less than 90
days. Further, because they contain less information than a data warehouse, they
have a more rapid response and are easier to learn and navigate. Finally they support
local rather than central control by conferring power on the using group. They also
empower an SBU to build its own decision support systems without relying on a
centralized IS department.
