The data is delivered in 1 table. Each dimension or metric is represented by a single column. Each row is equal to a hit. A hit is either a Page View, Screen view, Event, Transaction or Other.
The schema is designed to be fact only. This means it is trimmed for deducted/filtered dimensions. But there are some filtered metrics (bounces, goals) which we added for your convenience – but we recommend bulding these metrics  in SQL or favorite query language. Google Analytics metrics are very broad-purposed and typically not what your business needs.
