Description

Introduction

Google BigQuery is a fully managed and serverless data warehouse from Google Cloud. It is designed for high-performance analytics on massive datasets.It uses a distributed architecture. In addition, it separates storage and compute layers. This allows fast and scalable SQL-based querying. Moreover, it ensures efficient processing of large workloads.

This training focuses on internal architecture and query execution workflows. It also explains system-level processing concepts in detail.

Learner Prerequisites

• Basic knowledge of SQL (SELECT, JOIN, GROUP BY)
• Understanding of relational database concepts
• Familiarity with data warehousing fundamentals
• Basic awareness of cloud platforms and services
• Introductory understanding of analytics or ETL pipelines
