Oracle Database
Architecture
A
database is a collection of data treated as a unit. The purpose of a
database
is to store and retrieve related information. A database server is the
key to
information management. In general, a server reliably
manages a
large amount of data in a multiuser environment so that many users can
concurrently access the same data. A database server also prevents
unauthorized
access and provides efficient solutions for failure recovery.
- Enterprise
grid computing
creates large pools of industry-standard, modular storage and servers.
- With
this
architecture, each new system can be rapidly provisioned from the pool
of
components.
- There is no need to provide extra hardware to support peak workloads, because capacity can be easily added or reallocated from the resource pools as needed.
