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 deals with the development, maintenance, optimization, and management of data pipelines from various sources to enable efficient analysis and reporting. Data Engineers are heroes of the data management domain.

It is an essential part of any data science project as it involves 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.

Data engineers create efficient processes for quick extraction from different sources including databases and APIs (Application Programming Interfaces) so that the information can be used for further data analysis by a data scientist.

What is Data Engineering?

Data Engineers play a vital role in developing robust systems for secure data storage of this valuable information in data warehouses effectively thereby ensuring its availability when needed.

Skills required to become a Data Engineer

  • Knowledge of programming languages such as Python, Java, JavaScript, and SQL
  • Proficiency in using big data technologies like Hadoop, Spark, and Hive
  • Knowledge of data modeling techniques, such as relational, dimensional, and NoSQL
  • Experience with distributed systems such as Cassandra and MongoDB
  •  Familiarity with cloud platforms (AWS or Azure)
  •  Understanding of software engineering principles such as CI/CD data pipeline
  • Good knowledge of machine learning algorithms and their application to real-world problems.
  • Ability to interpret raw data for insights and making accurate projections.
  • Strong analytical and problem-solving skills to identify data-related issues, troubleshoot problems, and optimize data workflows
