Advanced T-SQL for Data Analysts (English)

€ 699,- (excl. VAT) 1 day Online

Description

In the training "Advanced T-SQL for data analysts" you will learn the very powerful concepts of windowing , ranking , subqueries and CTEs in one day. As a data analyst you can efficiently perform and solve all kinds of analyzes with this. In the course of the afternoon, work on the "challenge", in which all knowledge comes together. These are a number of larger SQL commands, where you have to decide for yourself which technique you can use best to find the solution. In this way, the training is really a whole, and you as a student are challenged to constantly apply the entire "toolset" learned. This training can be followed separately, but it is also the next step after the two-day basic training "T-SQL for data analysts".

De trainer weet ontzettend veel van T-SQL en weet dit goed over te brengen met een gezonde dosis enthousiasme. Tijdens de training bleef geen vraag onbeantwoord. Dit kon ik erg waarderen. De training heeft me geleerd dat er ontzettend veel mogelijk is met deze taal. Het is echter wel noodzakelijk om het meteen toe te passen in de praktijk anders zakt de kennis weg. Hier liep ik een beetje tegen aan tijdens de training. Er zat veel variatie op het gebied van kennis en ervaring met sql in de groep waarmee ik de training volgde. Om er voor te zorgen dat iedereen het uiterste uit de training kan halen, zou ik adviseren om de groepen op dit gebied wat meer homogeen te houden.

Hoop geleerd in de cursus van de trainer. Er is veel ruimte voor flexibiliteit, inbreng van eigen onderwerpen. De trainer past zijn programma daar op aan. De cursus is niet alleen theorie, het geleerde kan meteen in praktijk geoefend worden. Door de flexibele insteek helaas alleen geen syllabus om terug te lezen, maar ook na afloop van de cursus kunnen vragen nog gemaild worden.
