OneLake is a unified data lake included with every Microsoft Fabric tenant, designed to handle large volumes of data from various sources. It serves as a central hub for all your analytics data, ensuring one accessible copy for multiple analytical engines. This setup enhances collaboration and reduces management overhead by eliminating the need for multiple data lakes. With Microsoft Fabric, every tenant automatically gets a single OneLake, simplifying setup and management.

I’m Snorre

I’m a Data Engineer and Business Analyst with a background in Economics. I love diving into data and turning it into something meaningful using tools like Microsoft Fabric, Power BI, and Azure Data Factory. Over the years, I’ve worked on everything from data migrations to building reports and dashboards that help organizations really make the most of their data.

I’ve had the chance to work in a variety of environments, and I’m all about creating solid, scalable solutions that drive digital transformation. I also enjoy sharing what I know through training sessions and webinars, always looking to help others get more comfortable and skilled with data.


When I’m not working on data projects or teaching, you’ll probably find me outdoors—whether I’m working in the forest, traveling, or just hanging out with friends and family. I also like getting involved in testing out new Microsoft features, giving feedback to make sure they’re as useful as possible before they’re released.
