Abstract: A storage integration object is created in a database of a data warehouse system. The storage integration object identifies a storage location in a storage platform of a cloud storage provider system and a cloud identity object maintained by a network-based data warehouse system. The cloud identity object is associated, at the storage platform of the cloud storage provider, with a proxy identity object granted permission to access the storage location. An external stage object is created based on the storage integration object. The external stage object identifies the storage location and includes an association with the storage integration object. A command to load or unload data at the storage location is received. In response to the command, the data is loaded or unloaded, via the proxy identity object, at the storage location using the external stage object.

Abstract: Various systems and methods for air gesture-based composition and instruction systems are described herein. A composition system for composing gesture-based performances may receive an indication of an air gesture performed by a user; reference a mapping of air gestures to air gesture notations to identify an air gesture notation corresponding to the air gesture; and store an indication of the air gesture notation in a memory of the computerized composition system. Another system used for instruction may present a plurality of air gesture notations in a musical arrangement; receive an indication of an air gesture performed by a user; reference a mapping of air gestures to air gesture notations to identify an air gesture notation corresponding to the air gesture; and guide the user through the musical arrangement by sequentially highlighting the air gesture notations in the musical arrangement based on the mapping of air gestures to air gesture notations.
