PPT: Data Warehousing with Oracle Database 11g Release 2

There are several exciting new features with 11.2 on BI topics. But it is sad to see hybrid columnar compression NF at beta and now to know that it is only available with Exadata: ORA-64307: hybrid columnar compression is only supported in tablespaces residing on Exadata storage
