What is the purpose of having two folders in Azure Data-lake Analytics

Question

I am a newbie to Azure Data lake.

The below screenshot has 2 folders (Storage Account and Catalog), one for Datalake analytics and other data lake store.

My Question is why is the purpose of each folder and why are we using U-SQL for transformations when this can be done in the data factory.

Please explain the data flow process from the data store to the data lake.

Thanks you, Addy
