Data Engineering Essentials - SQL, Python and Spark

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 upon 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.

• Experienced application developers to gain expertise related to Data Engineering.

• Conventional Data Warehouse Developers, ETL Developers, Database Developers, PL/SQL Developers to gain enough skills to transition to be successful Data Engineers.

• Testers to improve their testing capabilities related to Data Engineering applications.

• Any other hands-on IT Professional who wants to get knowledge about Data Engineering with Hands-On Practice.

Prerequisites

• Logistics

  • Computer with decent configuration (At least 4 GB RAM, however 8 GB is highly desired)

  • Dual Core is required and Quad-Core is highly desired

  • Chrome Browser

  • High-Speed Internet

• Desired Background

  • Engineering or Science Degree

  • Ability to use computer

  • Knowledge or working experience with databases and any programming language is highly desired

Training Approach

Here are the details related to the training approach.

• It is self-paced with reference material, code snippets, and videos provided as part of Udemy.

• One can either use the environment provided by us or set up their own environment using Docker on AWS or GCP or the platform of their choice.

• We would recommend completing 2 modules every week by spending 4 to 5 hours per week.

• It is highly recommended to take care of the exercises at the end to ensure that you are able to meet all the key objectives for each module.

• Support will be provided either through Udemy Q&A.

Self Evaluation

The course is designed in such a way that one can self-evaluate through the course and confirm whether the skills are acquired.

• Here is the approach we recommend you to take this course.

  • The course is hands-on, you should practice as you go through the course.

  • You should also spend time understanding the concepts. If you do not understand the concept, I would recommend moving on and come back later to the topic.

  • Go through the consolidated exercises and see if you are able to solve the problems or not.

  • Make sure to follow the order we have defined as part of the course.

  • After each and every section or module, make sure to solve the exercises. We have provided enough information to validate the output.

• By the end of the course, then you can come to the conclusion that you are able to master essential skills related to SQL, Python, and Spark.
