We live in a data-driven world where data has an impact on the way people live. As a matter of fact, the quantity of digital data that exists is growing rapidly at a brisk, twinning every two years, and changing the way we live. And it’s already becoming increasingly unstructured. Multiple avenues have emerged in the Big Data landscape field with this data, including Data Science and Data Analytics.
Nowadays various frameworks have resolved the problem of storage, the main focus on data has shifted to processing this huge amount of data. Even though people tend to use these terms correspondently, they execute very significant but varied jobs, and there are many differences among these concepts. There has always been skepticism among these factors when it comes to the comparison of Big Data, Data Analytics, and Data Science.
Data Science is an amalgamation of various tools, algorithms, and machine learning principles with the target to discover hidden patterns from the original data. It also includes solving a problem in different ways to reach the solution and on the other hand, it includes designing and constructing new processes for data modeling and production using different prototypes, algorithms, predictive models, and custom analysis.
Roles and Responsibilities of Data Science
Data Scientists execute a probing analysis to discover insights from the data. They also use several advanced machine learning algorithms to identify the occurrence of a particular event in the future. This includes identifying hidden patterns, unknown correlations, market trends, and other useful business information. Following are the responsibilities of a Data Scientist:
- Data Cleansing and processing
