The Server
In today’s clients/server architectures, the mainframe functions as another
server on the network, offering reliable and available processing power, data
storage, and security. Organizations can processes mainframe data and
store
them on other servers. Some transactions and legacy system that are not as
frequently accessed also can be stored this way.
In addition to the mainframe, client/server architectures contain many
other
types of applications-specific servers, such as
data
warehouses,
file servers
and SQL databases.
Data warehouses separate real time data used by production online
transaction processing application
from
the historical data
used by office
worker
to
analyze
business
trends
and
produce
reports.
Production data
can
be
transferred to a data warehouse at intervals and restructured into a format
specifically designed for ad hoc query, analysis and reporting (Watson,
Houdeshel & Rainer, JR, 1997 p.146).
