The data warehouse technical architecture is a formal specification describing how
the warehouse system will be organized. It is a blueprint with the major components,
capabilities, and linkages required to meet the business requirements. The technical
architecture is not product-specific. A good architecture loosely couples components,
allowing for the replacement of one part without major disruption of other connected
parts.
It can be difficult to rise above the excitement of your first implementation to
plan the warehouse configuration for long term success; however, it's crucial. Architecture
planning helps avoid the unforeseen costs of re-work, missed deadlines, and unexpected
capital expenditures.
The TobiasGroup takes a four-step approach to creating a warehouse architecture:
describe the business context and systems environment; define the basic architecture;
identify standards; and define a product evaluation process that supports the architecture
and standards. Our engagements combine architectural expertise with project facilitation
to guide your IT professionals and business stakeholders to agreement on the warehouse
architecture.
In addition, TobiasGroup conducts architecture review engagements for clients
who wish to extend, tune, or modernize their existing data warehouse technical architecture.
Our focus during architectural reviews is tactical and practical. The Architecture
Review deliverable highlights the current architecture's strengths and shortcomings,
and delivers practical advice on overcoming those problems.
