Data in the platform is stored as data objects (a.k.a. data items) within data containers in the platform's data layer ("data store"). The platform uses object attributes to store object-metadata information. You can save and access data objects of any type — such as files, binary large objects (blobs), table items, and stream records. You can also group data objects of any type into collections — such as stream shards, NoSQL tables, or file-system directories — and perform high-level type-specific data manipulation.
