What is Data Engineering? Becoming a Data Engineer

Data is everywhere, and it’s growing at a faster pace than ever before. As data continues to become more critical in businesses across industry sectors, there arises the need for professionals who can manage and process data effectively. This is where data engineering comes in.

If you are an aspiring professional who is interested in pursuing a career in data science, you have probably heard about the field of data engineering. Data engineering is a crucial part of any data science project and it involves collecting, storing, processing, and managing large sets of data.

In this blog post, we will explore what data engineering is, its purpose, benefits, and the data engineering skills required to become a data engineer.

What is Data Engineering?

Data engineering is a field of data science that focuses on the development, maintenance, optimization, and management of data pipelines from various sources to enable efficient analysis and reporting. As key players in the data management domain, Data Engineers handle collecting, storing, transforming, visualizing, and managing large sets of structured or unstructured data using specialized techniques like ETL (Extract Transform Load), Data Warehousing, Data Mining, and Big Data Analytics.

They create efficient processes for quick extraction from different sources, including databases and APIs (Application Programming Interfaces), enabling data scientists to further analyze the data. Additionally, Data Engineers are crucial in developing robust systems for secure data storage, effectively managing this valuable information in data warehouses, and ensuring its availability when needed.
