A data lake is an infrastructure that permits different data sets from within a group to be combined and analysed together.

To analyse a data lake under GDPR, it is helpful to think of a data lake in two phases, which we analyse in our user guide.

The infrastructure phase

Here, the guide covers:

• Identify the entity that is hosting the data lake.
• Implement an intragroup data processing agreement.
• Check data localisation rules.
• Data protection impact assessment.
• Data lake governance committee.

The applications phase

Specifically, we look at:

• Data lake service provider becomes data controller.
• Instructions from each affiliate as (original) data controller.
• Mapping value transfers from data lake applications.
• Data lakes and applicable law.
• Anonymisation.
• Additional purposes that are "compatible".
• Data protection impact assessments.
