Overview of this book

Large volumes of data are generated daily from applications, websites, IoT devices, and other free-text, semi-structured data sources. Azure Synapse Data Explorer helps you collect, store, and analyze such data, and work with other analytical engines, such as Apache Spark, to develop advanced data science projects and maximize the value you extract from data. This book offers a comprehensive view of Azure Synapse Data Explorer, exploring not only the core scenarios of Data Explorer but also how it integrates within Azure Synapse. From data ingestion to data visualization and advanced analytics, you’ll learn to take an end-to-end approach to maximize the value of unstructured data and drive powerful insights using data science capabilities. With real-world usage scenarios, you’ll discover how to identify key projects where Azure Synapse Data Explorer can help you achieve your business goals. Throughout the chapters, you'll also find out how to manage big data as part of a software as a service (SaaS) platform, as well as tune, secure, and serve data to end users. By the end of this book, you’ll have mastered the big data life cycle and you'll be able to implement advanced analytical scenarios from raw telemetry and log data.

Technical requirements

To reproduce the examples and content in this chapter, you will need an Azure subscription and an Azure Synapse workspace. If you choose to load the data we offer as an example in this chapter, you will need to download the drone telemetry dataset from GitHub (approximately 123 MB) on your local machine. This dataset is stored as a comma-separated values (CSV) file and contains fictional data that was created specifically for this book. It can be found at https://github.com/PacktPublishing/Learn-Azure-Synapse-Data-Explorer/blob/main/Chapter%2003/drone-telemetry.zip. Make sure you extract the drone-telemetry.csv file from the compressed folder before using it.

The queries demonstrated in this chapter use Kusto Query Language (KQL). In addition to KQL, we will explore data in Synapse notebooks using Python. While these queries and notebooks are simple and we will describe what they do, teaching KQL or Python is not in the scope of this book. You should have...
