• What is Oracle Database In-Memory?

A new option for Oracle Information base 12c,
Oracle Information base In-Memory optimizes both
statistics and combined amount of work OLTP,
providing outstanding efficiency for dealings
while at some point supporting real-time
statistics, business intelligence, and
reviews. Oracle Information base in-Memory
provides a unique dual-format structure that
enables platforms to be at some point represented
kept in storage space using traditional row
structure and a new in-memory line structure.

The Oracle SQL Optimizer instantly routes
analytic concerns to the line structure and OLTP
concerns to the row structure, transparently
providing best-of-both-worlds efficiency. Oracle
database source 12c instantly preserves full
transactional reliability between the row and the
line formats, just as it preserves reliability
between platforms and indices today. The new line
structure is a pure in-memory structure and is
not persistent on hard drive, so there are no
additional storage space costs or storage space
synchronization issues.

Unlimited Scale Oracle Information source
In-Memory does not require all database data to
fit kept in storage space. Users can choose to
fill only efficiency delicate platforms or
partitions into storage space. Less efficiency
delicate data can reside on cheaper display or
hard drive. Queries execute transparently on data
residing on all three tiers storage space,
display and hard drive allowing Oracle
Information source In-Memory to be used with
databases of any size.

Real-Time Performance Oracle Information source
In-Memory implements state-of-the-art algorithms
for in-memory scans, joins and aggregation. These
optimizations enable Oracle database In-Memory to
run concerns at the astounding rate of billions
of rows per second for each CPU core. Analytics
that previously took hours or longer to run can
now complete in seconds, allowing real-time
business decisions.
5
Mixed Workload OLTP Mixed amount of work
databases run reviews and ad hoc concerns in
addition to OLTP dealings. It is common to create
dozens of indices on important platforms purely
to speed up reviews. The In-Memory line structure
eliminates the need for most of these analytic
indices by providing efficiency similar to having
an index on every line, but with much less
transactional overhead.Removing analytic indices
speeds up OLTP operations since the analytic
indices no longer need to be maintained by every
transaction.
