Azure Data Lake includes all the capabilities required to make it easy for developers, data scientists, and analysts to store data of any size, shape, and speed, and do all types of processing and analytics across platforms and languages. Compared to a hierarchical data warehouse which stores data in files or folders, a data lake uses a different approach; it uses a flat architecture to store the data. The typical data lake is a storage repository that can store a large amount of structured, semi-structured, and unstructured data. On the contrary, a data lake is a very useful part of an early-binding data warehouse, a late-binding data warehouse, and a Hadoop system. A data lake is usually a single store of data including raw copies of source system data, sensor data, social data etc and transformed data used for tasks such as reporting, visualization, advanced analytics and machine learning. A data warehouse is a repository for structured, filtered data that has already been processed for a specific purpose. This process allows you to scale to data of any size, while saving time of defining data structures, schema, and transformations. © 2020, Amazon Web Services, Inc. or its affiliates. They also give you the ability to understand what data is in the lake through crawling, cataloging, and indexing of data.
