数据工程基础知识讲解Data Engineering Essentials – SQL, Python and Spark

作为本课程的一部分，您将学习与使用SQL，Python和Spark建立数据管道有关的所有数据工程基础知识。

关于数据工程

数据工程不过是根据下游需求处理数据。作为数据工程的一部分，我们需要构建不同的管道，例如批管道，流管道等。与数据处理相关的所有角色都在“数据工程”下合并。通常，它们被称为ETL开发，数据仓库开发等。

Description
As part of this course, you will learn all the Data Engineering Essentials related to building Data Pipelines using SQL, Python as well as Spark.

About Data Engineering

Data Engineering is nothing but processing the data depending up on our downstream needs. We need to build different pipelines such as Batch Pipelines, Streaming Pipelines etc as part of Data Engineering. All roles related to Data Processing are consolidated under Data Engineering. Conventionally, they are known as ETL Development, Data Warehouse Development etc.
