Is your data lake open enough? What to watch out for

A facts lake is a program or repository that merchants facts in its uncooked structure along with reworked, reliable facts sets, and delivers both equally programmatic and SQL-based mostly entry to this facts for numerous analytics jobs these types of as facts exploration, interactive analytics, and machine discovering.
