Differenze
•
Oracle Database 11g Enterprise Edition (EE) provides efficient, reliable,
secure data management for mission-critical on-line transaction
processing applications, query-intensive data warehouses, and content
management and Web2.0 applications. It’s available on single and
clustered servers with no socket limitation.
•
Oracle Database 11g Standard Edition One (SE) delivers unprecedented
ease-of-use, power, and price/performance for workgroup, departmental,
and web applications on single servers with maximum capacity of two

Composite Partitioning
Virtual Columns - Partitioning
• Base table with all attributes ...
• ... is extended with the virtual (derived) column
• ... and the virtual column is used as partitioning key
CREATE TABLE accounts
(acc_no
number(10)
not null,
acc_name
varchar2(50) not null, ...
acc_branch number(2)
generated always as
(to_number(substr(to_char(acc_no),1,2)))

Data Compression for All Applications
• Oracle 9i Data Compression comprime i dati
solamente durante le operazioni “bulk load”, quindi
utile per DW e ILM
• Oracle 11g Advanced Compression comprime
anche su operazioni di insert e update
• La “compression ratio” tipica e’ 2x to 3x
