T
he architecture of multidimensional databases in many
respects follows the design of relational databases. Similarly
to relational databases, Microsoft SQL Server Analysis
Services supports a variety of architectures for accessing data:
.
Two-tier architecture, in which data is stored on the
server and moved to the client in response to a query
.
One-tier architecture, in which the data is stored on
the same computer as is the client application
.
Three-tier architecture, in which an Internet server sits
between the database server and the client
NOTE
We've used the term
tier
to describe these architec-
tures. We use this term to describe physical layers—
components of each layer are separate applications
and can even run on separate machines. If you choose
to look at the tiers as logical ones—layers of protocols
between components—you would get different
numbers of layers (tiers).
