Tabular data is stored in a Spark SQL database, and retains the same data structure as data released in baskets (1 row per participant, with field-instance-array columns). Bulk data is stored in a folder structure. Please see here for more information, and here for our Github notebooks which give some examples of how to query and extract Spark SQL and bulk data.
