Oracle SQL performance

It is extremely hard to write efficient SQL without having a thorough understanding of the Oracle optimizer. We therefore first discuss its characteristics, and determine where, and how, we can influence its behaviour. A number of techniques are discussed: creation and use of indexes, use of hints, the importance of statistics gathering. The tools available to evaluate the optimization process and the queries we write, are discussed as well: Explain, SQL Trace, autotracce.

Finally, the impact of the use of PL/SQL as an alternative to writing SQL statements is introduced, and its advantages discussed.

Participants have the opportunity to practise all the discussed topics during practical labs.

Reviews

     
ok, maar in ons geval meer als achtergrondinfo (, )
     
Ok, doch eerder ervaren als een overview dan een echte cursus. Vele items vragen nog veel uitzoekwerk achteraf. (, )
     
Er zou een elektronische versie beschikbaar moeten zijn, met referentiemateriaal. (, )
     
tres interessant - donné un peu rapidement - pourrait etre étalé sur 3 jours? (, )
     
good, have seen a lot (, )
     
Goed niveau. Zeer interessant en direct toe te passen (, )
     
zeer interessant, misschien niet alles van toepassing in onze situatie (, )
     
Ter inleiding goed, echter ik was in de veronderstelling dat er meer SQL-tuning met opdrachten aan bod kwamen. (, )
     
Deze cursus heeft zeker toegevoegde waarde, maar is redelijk theoretisch. (, )
     
one extra day -> exercises (, )
