Big data has created a huge impact in a wide variety of industries such as finance, banking, manufacturing, healthcare, logistics, and government. With such a large volume of data, companies can make more informed and better business decisions.
That’s why it is no surprise to see that big data is also generating numerous job opportunities. According to the Bureau of Labor Statistics, the demand for math-skilled professionals is expected to increase exponentially by 2026 due to big data. Yet, this exponential growth also means that you need to have an industry-relevant resume.
Now, what is big data? It is the collection of a large volume of structured, unstructured, and semi-structured data. Big data is also characterized by the speed at which it’s generated. Generally, big data is produced in real-time. This information is used for data analysis, predictive analysis, and machine learning. Big data comes from a wide variety of sources, depending on the industry and project. For example:
People usually define it as too complex datasets that can’t be processed with traditional relational databases, which is true. Big data is stored in data lakes, which can support multiple data types. These data lakes are usually based on Hadoop clusters and NoSQL databases. That’s why including your knowledge of those tools in your resume is crucial for big data careers.
