Big Data is one of the leading tech trends that is benefiting businesses by allowing them to understand their customers better, effective fraud and anomaly detection, improving efficiency, cost optimization, and subsequently leading to an effective decision-making process. The demand for Big Data professionals is almost in every sector whether it be IT, finance, manufacturing, retail, etc. Other than that, there are various job roles that fall under the Big Data domain like Big Data Engineer, BigData Architect, etc. Hence, if you’re considering making a career in Big Data, you can surely go for it.
What is Big Data?
Big Data is concerned with the collection of huge data associated with characteristics like large variety, more velocity along with increased volume simply known as 3 Vs. There are primarily 3 types of Big Data – Structured data, Unstructured data, and Semi-structured data. This voluminous structured, semi-structured, or unstructured data is processed to gather useful insights for subsequently making effective business decisions, etc.
Is Big Data in Demand?
According to numerous research, it has been found that data science-related jobs have a very high demand and will grow by 31 percent in the next few years. Many top companies are always in need of professionals who have knowledge of data science along with a proper skill set. Also, these highly demanding jobs have good pay for those with the right expertise.
