 Packages
 Triggers for each row
 Synonyms
 Snapshots
 Flashback

 Pluggable databases (since 12c in Oracle)
 Auto-increment values (since 12c in Oracle)

10. Transaction Control
11-7-2016
SQL Server

SQL Server
Commits on default after every command. It is complex to
change this behavior.
Oracle
Commits when you commit. More control.

11. Transactionlog

SQL Server

Oracle
Archivelog / noarchivelog
Oracle is using redo-logs. When a redo-log is full, it makes
a copy to a archivelog and rotates to the next member of
the redo-log.
SQL Server
Full Recovery / simple mode
SQL Server writes transaction-data to the transactionlog.
In full recovery it maintains this data until a backup has
been made. In simple mode it maintains the transaction-
log data during the transaction.

rman

SQL Server
Via SSMS (SQL Server Management Studio)
tool from supplier (ie NetBackup SQL client)

15. Monitoring
Oracle: Oracle Enterprise Manager (OEM) / Grid Control
SQL Server:
- Alerts
- System Centre Operations Manager (SCOM)
In OEM you can modify settings of the database, in SCOM
that is not possible. SCOM is only for monitoring. If you
want to change settings, use SSMS.

Page Life Expectency (PLE)
PLE is the time in seconds how long the page stays in the
bufferpool. This is related to the memory-pressure. If the page
has been flushed from the bufferpool, it needs to be loaded
from disk.
