摘要：
Architecture that defines a logical database that shares physical resources with a containing physical database. The architecture isolates the relational engine system metadata parts of a database in horizontal scopes to form separate namespaces, and shares the underlying storage engine system metadata. Sharing physical database resources enables efficient input/output (I/O) utilization and instantaneous database creation and growth. In addition, logical databases can be backed up as a single transactionally consistent unit.
