The warehouse may be distributed for load balancing,
scalability, and higher availability. In such a distributed
architecture, the metadata repository is usually replicated with
each fragment of the warehouse, and the entire warehouse is
administered centrally. An alternative architecture,
implemented for expediency when it may be too expensive to
construct a single logically integrated enterprise warehouse, is
a federation of warehouses or data marts, each with its own
repository and decentralized administration.
Designing and rolling out a data warehouse is a complex
process, consisting of the following activities5.
