What is Data Science?
Data science is an interdisciplinary field that houses the scientific methods, processes, algorithms, and systems to extract knowledge. By studying this information, data scientists can gain insight. This profession integrates techniques from statistics, computer science, and domain-specific knowledge to analyse and interpret complex data sets for the purpose of making future predictions or strategies.
Today, data science is the key driver of decision-making in various sectors, enabling them to get useful insights from data. Data science helps businesses improve their understanding of consumers, making it possible to offer better services, enhance operations, and develop new products through innovation.
Healthcare also benefits from this since it enables the identification of diseases before they become serious enough to administer personalised care. Conversely, some nations have embraced it as a tool for making policies and improving public service delivery. The fact of the matter is that data science converts raw figures into something worthwhile, which leads to progress.
History of Data Science
Data science evolution is traced back to the 1960s when the term data began gaining prominence. Data science was born from statistics and data analysis and then developed through the utilisation of computers and databases during the 1980s, leading to more advanced forms of data manipulation and storage in the 1990s. It was after this that data mining came into existence, followed closely by the surge in big data during the early 2000s which relied heavily on the use of the internet as well as social media platforms. These days, data science remains a comprehensive discipline incorporating modern technologies.
