Data Lake

A data lake is a centralized repository where large volumes of structured, semi-structured, and unstructured data are stored for further processing. Data lakes can store vast amounts of raw data in their native format whereas traditional databases store data in hierarchical table format. Data lakes are scalable and cost-effective. They facilitate organizations to harness data from different sources such as social media, business applications, IOT devices, etc. It helps them work on advanced analytics, predictive analytics, Machine Learning (ML), and such data related activities leading to data-driven decisions.
