By: Newton Alex

Overview of this book

Azure is one of the leading cloud providers in the world, providing numerous services for data hosting and data processing. Most of the companies today are either cloud-native or are migrating to the cloud much faster than ever. This has led to an explosion of data engineering jobs, with aspiring and experienced data engineers trying to outshine each other. Gaining the DP-203: Azure Data Engineer Associate certification is a sure-fire way of showing future employers that you have what it takes to become an Azure Data Engineer. This book will help you prepare for the DP-203 examination in a structured way, covering all the topics specified in the syllabus with detailed explanations and exam tips. The book starts by covering the fundamentals of Azure, and then takes the example of a hypothetical company and walks you through the various stages of building data engineering solutions. Throughout the chapters, you'll learn about the various Azure components involved in building the data systems and will explore them using a wide range of real-world use cases. Finally, you’ll work on sample questions and answers to familiarize yourself with the pattern of the exam. By the end of this Azure book, you'll have gained the confidence you need to pass the DP-203 exam with ease and land your dream job in data engineering.

Chapter 8: Ingesting and Transforming Data

Welcome to the next major section of the book. In this section, we will focus on designing and developing data processing systems.

In the last chapter, we learned about implementing the serving layer and saw how to share data between services such as Synapse SQL and Spark using metastores. In this chapter, we will focus on data transformation—the process of transforming your data from its raw format to a more useful format that can be used by downstream tools and projects. Once you complete this chapter, you will be able to read data using different file formats and encodings, perform data cleansing, and run transformations using services such as Spark, SQL, and Azure Data Factory (ADF).

We will cover the following topics in this chapter:

  • Transforming data by using Apache Spark
  • Transforming data by using Transact-SQL (T-SQL)
  • Transforming data by using ADF
  • Transforming data by using Azure Synapse pipelines
  • ...
