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

sockets

• 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

Data Compression for All Applications
