Understanding Data Science and Data Analytics: An Overview
what is data science and data analytics
Data Science is an interdisciplinary field that utilizes statistical analysis, computational skills, and domain expertise to extract insights and knowledge from structured and unstructured data. It encompasses a broad range of techniques, including machine learning, data mining, and big data technologies, to make predictions and inform decision-making. Data Analytics, on the other hand, is a subset of data science that focuses specifically on examining data sets to draw conclusions about the information they contain, often involving descriptive, diagnostic, predictive, and prescriptive analytics. While data science looks at the overall process of extracting value from data, data analytics is concerned with the techniques and tools used to analyze data and provide actionable insights.
