Gleich vorweg: ich kenne die Autorin und arbeite mit ihr zusammen.Das Buch enthält Mini-Projekte, sog. "Rezepte" für alle Bereiche, mit denen man als Power BI / Power Query-Entwickler*innen im täglichen Leben konfrontiert wird. Als Leser*in bekommt man im Rezept zunächst alle notwendigen "Zutaten" (technische Anforderungen/Voraussetzungen) präsentiert und kann dann direkt an die Umsetzung gehen. Diese Strukturierung erlaubt es auch erfahreneren Lesern*innen flexibel zu den fortgeschritteneren Themen zu springen, da die Kapitel voneinander unabhängig gestaltet sind.Auch Fortgeschrittene PowerBI / PowerQuery-Entwickler*innen werden von diesem Buch profitieren. Andrea konzentriert sich auf das Notwendige und lässt die Schnörkel aus. Damit kann man ein Thema schnell erfassen und umsetzen.Aus meiner Sicht ist das Buch definitiv eine Referenz für alle, die sich mit dem Thema Power Query beschäftigen. Es hilft Anfängern*innen und Fortgeschrittenen gleichermaßen und sollte in jedem Regal stehen, wo mit Power BI, Synapse Pipelines und Azure Data Factory gearbeitet wird.
