Business Intelligence with Databricks SQL

By: Vihag Gupta

Overview of this book

In this new era of data platform system design, data lakes and data warehouses are giving way to the lakehouse – a new type of data platform system that aims to unify all data analytics into a single platform. Databricks, with its Databricks SQL product suite, is the hottest lakehouse platform out there, harnessing the power of Apache Spark™, Delta Lake, and other innovations to enable data warehousing capabilities on the lakehouse with data lake economics. This book is a comprehensive hands-on guide that helps you explore all the advanced features, use cases, and technology components of Databricks SQL. You’ll start with the lakehouse architecture fundamentals and understand how Databricks SQL fits into it. The book then shows you how to use the platform, from exploring data, executing queries, building reports, and using dashboards through to learning the administrative aspects of the lakehouse – data security, governance, and management of the computational power of the lakehouse. You’ll also delve into the core technology enablers of Databricks SQL – Delta Lake and Photon. Finally, you’ll get hands-on with advanced SQL commands for ingesting data and maintaining the lakehouse. By the end of this book, you’ll have mastered Databricks SQL and be able to deploy and deliver fast, scalable business intelligence on the lakehouse.

User-facing table access control

Diving further into the security model, let’s discuss table access control. In essence, table access control requires programming a user’s privileges to perform operations on a data object/asset. The owners of data objects or administrators will implement this programming with standard database security statements.

First, we will discuss users, objects, operations, and privileges. Then, we will bring them all together and see how we can program them with user-facing table access control.

Users, groups, and service principals

Databricks SQL inherits users and groups from the Databricks Lakehouse platform. Users and groups can be managed from the Admin Console area of the Databricks platform.

Note to Administrators

At the time of writing, user and group management is only available from the Data Science & Engineering and the Machine Learning persona experiences.
