• Oracle Data Partitioning

• Oracle Advanced Compression

• Hybrid Columnar Compression

Mejoras en Oracle Database 11g Storage Efficiency

2a


Oracle Data Partitioning Option

Partition tables into “smarter” pieces

•Queries execute faster against smaller partitions

•“Mandatory” for DWH operations

Increases performance

•24*7 access to critical data Increases

availability

•Divide large tables into smaller, more manageable subsets.

•DBA operations benefit (data loads, backup, recovery)

•Partitioning Advisor new in Oracle DB 11g

Enables simpler management

•Individual partitions can be assigned to specific storage areas

•Reduces the cost of retaining data

Enables storage

cost optimization

•Applications remain unchanged Transparent to applications

Mejoras en Oracle Database 11g Seguridad

2c


• Transparently encrypts data-at-rest in Oracle

databases and securely manages the encryption keys

• Protects against theft or loss of disks and backup

media

• Stops OS users from inspecting the tablespace files

Advanced Protection for the Oracle Database

Transparent Data Encryption (TDE)

• Locks-down the database network connections

• Prevents network sniffing and replay attacks

Network

Encryption

• Signs-in database users via Kerberos, PKI, or Radius

• Avoids weak passwords that can be stolen or cracked

Find the top 5 stores that are the furthest below forecast

SELECT store_id, loc,

sales, forecast FROM

(SELECT * FROM

(SELECT s.*,

PREDICTION

(CREATE REGRESSION

FOR sales USING *)

OVER () as forecast
