Introduction to Big Data

Before diving into How to Become a Big Data Engineer, it's essential to understand the term ‘Big Data.’

In the early 2000s, data generation was relatively limited. However, with the rise of social media platforms and multinational corporations, data generation has surged exponentially. According to Statista, global data volume is projected to reach 180 zettabytes by 2025—a staggering amount. 

Here are the different types of Big Data:

a) Structured Data

b) Unstructured Data

c) Semi-structured Data

Big Data refers to enormous datasets that are too large to be stored, processed, and analysed using traditional methods. To manage Big Data, frameworks like Hadoop, Spark, Cassandra, and Apache Storm are employed.

Big Data Engineers use these frameworks to handle and analyse massive datasets. Now, let's explore the role of a Big Data Engineer and how to pursue this career path.

Who is a Big Data Engineer?

A Big Data Engineer is a professional responsible for developing, maintaining, testing, analysing, and evaluating a company's data systems. Big Data refers to extremely large data sets that companies commonly collect during their business operations.

When used effectively, Big Data can significantly enhance an organisation's efficiency, profitability, and scalability. However, without a Big Data Engineer to build systems for collecting, maintaining, and extracting data, the potential benefits of Big Data remain untapped. Thus, Big Data Engineers play a crucial role in helping companies manage and leverage their Big Data for maximum advantage.

What is the Role of a Big Data Engineer?

As an essential part of a data-focused organisation, a Big Data Engineer holds an array of responsibilities. Below, we provide a breakdown of these key responsibilities, including the design, development, and implementation of robust and scalable data pipelines for various Data Engineering Projects:
