Die Welt wird von Daten angetrieben, aber welche Sprache spricht sie? Sie spricht SQL. Für jeden, der in die Welt der Technologie, Datenanalyse oder Business Intelligence einsteigen möchte, ist die Beherrschung der Structured Query Language (SQL) keine Option mehr – sie ist eine Notwendigkeit. Dieses Buch ist Ihr Schlüssel, um diese Sprachkompetenz zu erlangen.
SQL Sprechen entmystifiziert die Sprache der Daten und verwandelt sie von einer einschüchternden technischen Hürde in ein zugängliches und leistungsstarkes Werkzeug. Dieser Leitfaden verfolgt einen methodischen, praxisorientierten Ansatz und verwendet die kostenlose und leichtgewichtige SQLite-Datenbank-Engine sowie die bekannte Chinook-Beispieldatenbank, sodass Sie durch praktische Anwendung lernen. Sie werden nicht nur über Konzepte lesen; Sie werden innerhalb von Minuten Ihre ersten Abfragen schreiben und von Grund auf praktische Fähigkeiten aufbauen.
Im Inneren lernen Sie:
-
Die Grundlagen meistern: Beginnen Sie mit der zentralen SELECT-Anweisung und bauen Sie Ihre Fähigkeiten beim Filtern, Sortieren und Manipulieren von Daten schrittweise aus.
-
Informationen verbinden: Erlernen Sie die Kunst des JOIN, um Daten aus mehreren Tabellen zu verknüpfen und komplexe Geschäftsfragen zu beantworten.
-
Daten formen und transformieren: Verwenden Sie Funktionen und bedingte Logik, um neue Werte im laufenden Betrieb zu bereinigen, zu formatieren und zu berechnen.
-
Zusammenfassen und analysieren: Lernen Sie, Aggregationen, GROUP BY und fortgeschrittene Fensterfunktionen zu nutzen, um Rohdaten in aussagekräftige Erkenntnisse zu verwandeln.
-
Von Grund auf neu erstellen: Gehen Sie über das Abfragen hinaus und lernen Sie, Ihre eigenen Datenbanktabellen mit robusten, integritätssichernden Nebenbedingungen zu entwerfen und zu CREATE.
-
Professionell schreiben: Schaffen Sie eine solide Grundlage für das Schreiben von sauberem, lesbarem und effizientem Code – eine Fähigkeit, die Amateure von Profis unterscheidet.
Dieses Buch, dessen Kern die Klarheit ist, folgt einer logischen Progression von einfachen Konzepten zu fortgeschrittenen Techniken. Es ist der perfekte Ausgangspunkt für angehende Datenanalysten, Softwareentwickler, BI-Profis oder jeden, der mit Daten interagieren muss. Sie lernen nicht nur Befehle, sondern verstehen auch die Prinzipien dahinter.

Store description
We first started out as “The Paperback Exchange,” a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become “PBShop.” This transition has only allowed us to blossom as we now ship thousands of titles to book lovers across the globe. We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first visit or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book. We are a company who put our customers at the centre of everything we do as we understand the importance of reading because once you learn to read, you will forever be free. There are a whole lot of things in this world of ours that we are yet to explore, which is why we will forever inspire curious minds.…
