Waarom kiezen voor deze opleiding?

De prestaties van een Oracle-database optimaliseren is van cruciaal belang voor databasebeheerders (DBA’s). Een slecht presterende SQL-query kan aanzienlijke vertragingen en inefficiënties veroorzaken. Deze training biedt de kennis en vaardigheden die nodig zijn om slecht presterende SQL-statements te identificeren en te verbeteren met behulp van geavanceerde tools en methodologieën van Oracle Database 11g en 12c.

Wat je zult leren:

• Oracle Methodologie: Begrijp de systematische aanpak om slecht presterende SQL-statements te identificeren en te optimaliseren.
• Prestatieanalysetools: Leer werken met Oracle-tools zoals de Automatic Workload Repository (AWR) en SQL Performance Analyzer om prestaties te bewaken en te verbeteren.
• Geavanceerde optimalisatietechnieken: Ontdek hoe je Oracle’s ingebouwde functies kunt gebruiken voor efficiënter SQL-tuning.
• Praktische toepassingen: Werk aan praktijkopdrachten die echte uitdagingen simuleren, zodat je direct ervaring opdoet in het oplossen van databaseprestatieproblemen.

Wie zou moeten deelnemen?

Deze opleiding is ideaal voor:

• Databasebeheerders (DBA’s): Professionals die verantwoordelijk zijn voor het beheren en optimaliseren van Oracle-databaseprestaties.
• SQL-ontwikkelaars: Ontwikkelaars die efficiënte SQL-statements willen schrijven en verbeteren.
• IT-professionals: Iedereen die betrokken is bij databasebeheer en -optimalisatie in een Oracle-omgeving.
• Geïnteresseerden in Oracle-certificeringen: Personen die zich willen voorbereiden op geavanceerde Oracle-certificeringen.
