Db2 for z/OS SQL performance

Quality and efficiency are the main concerns for application developers. This also applies to the aspects of data access. After following this course, participants will be able to understand how the Db2 optimizer is able to optimally implement SQL queries, and they will be able to apply techniques to further optimize those SQL queries.

Query optimization and a good concurrency are emphasized. Also discussed are some aspects of logical and physical design, and the statistical information in the Db2 catalog used by the optimizer.

During the practical sessions the participants will have ample opportunity to practise all the discussed topics.

Ik heb een goed inzicht gekregen in de nieuwe mogelijkheden van DB2. Peter weet ook heel veel en geeft (soms zelfs teveel) achtergrondinformatie. (, )
Prima, weer een boel opgestoken (, )
prettig en zeer leerzaam (, )
Erg goede inhoud. Wel veel; gelukkig is de documentatie goed te gebruiken als naslagwerk (, )
goede docent, goede inhoud (, )
This training helped me understand DBA and Datamanager implementations and decisions or choices (, )
This training will help me with request dev (, )
Bon cours en général, assez difficile mais qui apporte un réel plus à la programmation future au niveau professionnel.J'ai vraiment appris des choses. (, )
Très bons tips pour écrire le DB2, comprendre l'implémentation et l'exécution du DB2. (, )
Aanvankelijk vond ik het moeilijk te volgen, het werd mij pas vooral duidelijk na de eerste oefening. Misschien iets te vlug over de theorie gegaan, en te lang bij misschien minder belangrijke zaken voor ons? (, )
