What is Data Lake?

Data lake is a centralised repository which stores enormous amounts of structured, semi-structured, and unstructured data in its native format. It is typically used for Master Data Management – MDM cleans and enriches data, ensuring that the data is accurate, complete, and consistent before it is loaded into the data lake. This is then used to store and process the data, making it available for advanced analytics and machine learning tasks. Data lakes can manage raw data from various sources, such as IoT devices, social media, and transactional systems, at a lower cost compared to traditional data warehouses. They support advanced analytics, machine learning, and data discovery initiatives.
