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.

Native multi-tenancy for database system

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.

Native multi-tenant encryption for database system

Techniques are described for providing sign-on within a trusted environment across multiple application servers. For example, a method can be provided for a single sign-on within a trusted environment across application servers. The method comprises, by a first application operating within the trusted environment, connecting to a first application server via a first access channel, and retrieving an authentication token from the first application server via the first access channel. The method further comprises, by a second application operating within the trusted environment, connecting to a second application server via a second access channel, and authenticating with the second application server with the authentication token.

Self-single sign-on

A system may include reading a provider database mapping of file identifiers to page numbers of the provider database, determining one or more shared database objects of the provider database based on the provider database mapping, and registering the one or more shared database objects in a local namespace of a reader database.

Sharing of database objects

A system may include a provider database, a reader database, and a database management system. The provider database may include a provider data area having a plurality of provider block addresses, and the reader database may include a reader data area having a plurality of reader block addresses, and a mapping of provider-specific identifiers to block addresses of the plurality of provider data pages and of reader-specific identifiers to block addresses of the plurality of reader data pages. The database management system may modify a database object of the reader database, the object being is associated with a provider-specific identifier; and modify the mapping to map the provider-specific identifier to a first block address of one of the plurality of reader data pages.
