Let’s say you’re the type of person to commit to a course from start to finish, from beginner to expert. This course may be for you. Offered by IBM, this data engineering course is a professional certificate consisting of 16 series and can be completed in 6 months if you commit 10 hours a week.
In this course, you will learn the most up-to-date practical skills and knowledge data engineers use in their daily roles. You will then dive into creating, designing and managing relational databases & applying database administration (DBA) concepts to RDBMSs such as MySQL, PostgreSQL, & IBM Db2. Over time you will develop a working knowledge of NoSQL & Big Data using MongoDB, Cassandra, Cloudant, Hadoop, Apache Spark, Spark SQL, Spark ML, and Spark Streaming.
By the end of the course, you will be able to implement ETL & Data Pipelines with Bash, Airflow & Kafka; architect, populate, and deploy Data Warehouses; and create BI reports & interactive dashboards.
Wrapping Up
In this blog, I aimed to walk you through learning the fundamentals of data engineering from bite-sized courses to the complete certification. Everybody learns at different levels and we all learn in different ways too. Choosing a course that is right for you is important in learning the fundamentals of data engineering.
