A Data Lake is similar to that of a data warehouse, but it allows for the flow and storage of unstructured data sources in addition to the structured data in an enterprise data warehouse or data mart. The idea of a lake is such that water flows from various paths into the reservoir and then flows out.

Functions of a Data Lake

  • Data Ingestion
  • Data Storage and Retention
  • Data Processing
  • Data Access
