In diesem zweistündigen Projekt wirst du Daten aus Datenbanktabellen mit dem SQL-GROUP-BY-Statement in Verbindung SQL-Aggregationsfunktionen abrufen. Wir werden die Aggregationsfunktionen COUNT(), SUM(), MIN(), MAX() und AVG() kennen lernen. Aggregationsfunktionen werden verwendet, um Zeilen einer Tabelle in einen einzigen Wert zusammen zu fassen. Außerdem wirst du lernen, wie du das gruppierten und aggregierten Ergebnis mit HAVING filtern kannst.
Hinweis: Du musst kein Data Analyst sein, um in diesem angeleiteten Projekt erfolgreich zu sein! Grundlegende Kenntnis von SQL SELECT- und WHERE-Statements sollte genügen.
