Data lake definition

A data lake is a centralized repository or system that stores, processes, and secures large amounts of data. It stores data in its raw format, which can be unstructured, semistructured, or structured. With a data lake, you can process all kinds of data, no matter the size or type. You don’t have to structure your data to store it in a data lake. Also, you can run different types of analytics on it, like dashboards, big data processing, visualization, machine learning, real-time analytics, and more.
