Foundations of Data Science

The beginnings of data science can be traced back to traditional statistics, where researchers relied on mathematical formulas and manual computation. The arrival of computers in the mid-1900s marked a turning point, making it possible to process information faster and more accurately. This blend of statistical theory and computational technology laid the groundwork for what would later evolve into the modern data science ecosystem.

The Rise of Big Data

The digital revolution brought an unprecedented surge of information. The internet, mobile devices, and social media collectively created an explosion of data that traditional systems couldn’t manage. This gave birth to the concept of big data vast, complex datasets requiring advanced tools for processing and analysis. Technologies like Hadoop and Spark emerged to handle this data wave, allowing organizations to generate real-time insights and strategic value.
