Abstract: A shared database platform implements dynamic masking on data shared between users where specific data is masked, transformed, or otherwise modified based on preconfigured functions that are associated with user roles. The shared database platform can implement the masking at runtime dynamically in response to users requesting access to a database object that is associated with one or more masking policies.

Abstract: Embodiments of the present disclosure may provide a streamlined process for performing operations, such as data sharing and data replication, using multiple accounts. A global identity (also referred to as an organization user) may be employed, where the global identity may have access to multiple accounts across the same or different deployments. The global identity may switch between accounts from its login session and perform various tasks in the context of different accounts without undergoing further authentication.

Abstract: Row-level security (RLS) may provide fine-grained access control based on flexible, user-defined access policies to databases, tables, objects, and other data structures. A RLS policy may be an entity or object that defines rules for row access. A RLS policy may be decoupled or independent from any specific table. This allows more robust and flexible control. A RLS policy may then be attached to one or more tables. The RLS policy may include a Boolean-valued expression.

Abstract: A method of implementing object tagging framework starts with the processor receiving a tag creation command including a tag name. In response to the tag creation command, the processor creates a current tag. The processor then receives an association command, the tag name and a source object identifier. The processor determines a source object associated with the source object identifier. The source object includes a tag value. The processor associates the current tag with the source object. The processor receives a replication command including the source object and a target object. The processor causes replication of the source object to the target object that comprises replicating the current tag with the tag name and the tag value in the source object to the target object. Other embodiments are also described herein.

Abstract: Using container-centric managed access, an administrator is enabled to define a set of future grants for each object that will be created in the future in a container managed by the administrator. When a user creates a database object, the system checks the future grants to determine if any apply to the user, the database object, or the combination. Any applicable future grants are applied to the database object before the user is allowed to modify it. As a result, the administrator is enabled to control the privileges associated with the database object even before the database object is created, while restricting individual object owners from managing privileges on their owned objects.
