Summary
You can't build on data you can't find. OneLake gives your organization one storage layer where all Fabric data lives. The OneLake catalog shows you what exists across workspaces, and shortcuts let you connect to it without creating copies. For data that flows continuously, Real-Time hub provides the same discovery experience for eventstreams and KQL tables.
Now you know how to find stored data, evaluate whether it fits your needs, and connect to it. You also know where to look when data arrives in real time instead of batches.
