Develop essential engineering skills with expert instruction and practical examples.
A data warehouse is a repository of historical data that is queried to answer questions, gain insight from data, and make business decisions. BigQuery is Google's product for data warehouse. It is designed to store and query terabytes, even petabytes of data without we need to setup and manage any infrastructure.
It is not a transactional database for day-to-day operation. BigQuery supports standard SQL, so if you ever develop with relational database like Oracle, PostgreSQL, MySQL, Microsoft SQL Server, etc, it is easy to familiarize yourself with BigQuery. There are a few BigQuery functions to support modern-day requirements, and learning about them will make your job easier.
There is no infrastructure required. We don't need to worry about the size of storage, number of processors, or memory allocation for processing query. BigQuery scales automatically to run query, and then release the resource when it is done.
We don't even charged for memory or processor allocation. Google provides sample database for practice and trial. This course has several topics:an introduction, where we will see what this course aboutwhat is data warehouse and in which part BigQuery take roleshow we can create a simple data pipeline, including data input, data cleansing, and data visualizationtools and methods that can be used for data engineering, particularly on data ingestion from various sources to BigQuerydata visualization using Google Sheets & Data StudioThis course is for people with basic technical knowledge on SQL.
