Data Lake

What is a data lake?

A data lake is a central storage location in which large volumes of structured and unstructured data are collected in their original raw format. Unlike a data warehouse, where data is transformed before storage, a data lake enables flexible analysis without prior data modeling. This flexibility makes it ideal for big data analyses and artificial intelligence.

Advantages and areas of application

The main advantages of a data lake are cost efficiency, flexible data processing and the ability to use different analysis tools. Data lakes are used in areas such as marketing, research and IoT, where large amounts of data need to be collected and analyzed. They provide an optimal basis for machine learning and predictive analytics, as all data sources are available in a central repository.
