How Business Modeling Rationalizes Data Warehousing
A Kalido White Paper by Neil Raden, Hired Brains, Inc.

Abstract
Data warehouses were conceived as orderly, mostly static databases,
accessed in a controlled way to service business reports. With ever
shortening business cycles, the externalization of business brought on
by the Internet, the massive scale and relatively low cost of computing
hardware and the flattening of the competitive playing field as a
result, the mission of data warehouses is changing dramatically.
Existing tools and methodologies cannot provide the speed and agility
that is needed. A better way to model and manage these assets is
needed. An alternative to a data-centric approach is a model-driven
approach or, in practice, a model-driven architecture. Model-driven
architecture has proven to be highly effective in delivering useful
results with good ROI in a short period of time. In particular, a
model-driven architecture can excel at providing high levels of
reusability, flexibility and maintainability. The concept behind
model-driven architectures is to build declarative models, and separate
the impositions of current data structures, applications and sources
from the definitions of the business. This allows for business users to
discuss the business in terms that they understand.
