The healthcare sector produces an enormous amount of data every single day, ranging from electronic health records (EHRs) and lab results to information from wearable devices and imaging systems. Thanks to big data technologies, healthcare providers can gather, store, and analyze this wealth of information to enhance patient care, cut costs, and push forward medical research. By harnessing the power of big data, the healthcare landscape is evolving to become more predictive, personalized, and efficient.
