Abstract: Systems and methods include creation of a first instance of a tenant object in a database instance, association of the first instance of the tenant object with a first plurality of database artifacts including first data associated with the first instance of the tenant object, creation of a second instance of the tenant object in the database instance, association of the second instance of the tenant object with a second plurality of database artifacts including second data associated with the second instance of the tenant object, and reception and response to queries on the first data associated with the first instance of the tenant object and to queries on the second data associated with the second instance of the tenant object.

Abstract: A database system includes a persistent storage system, a memory storing metadata defining a tenant object and a plurality of database artifacts, a first instance of the tenant object, the first instance associated with a first plurality of the database artifacts including first data associated with the first instance of the tenant object, and a second instance of the tenant object, the second instance associated with a second plurality of the database artifacts including second data associated with the second instance of the tenant object. A processing unit is to execute program code of a database instance to cause the database system to encrypt the first data associated with the first instance of the tenant object using a first public encryption key and store the encrypted first data in the persistent storage system, and encrypt the second data associated with the second instance of the tenant object using a second public encryption key and store the encrypted second data in the persistent storage system.
