The uses of SCHEMA and DATABASE are interchangeable – they mean the same thing. CREATE DATABASE was added in Hive 0.6 (HIVE-675).  The WITH DBPROPERTIES clause was added in Hive 0.7 (HIVE-1836).

MANAGEDLOCATION was added to database in Hive 4.0.0 (HIVE-22995). LOCATION now refers to the default directory for external tables and MANAGEDLOCATION refers to the default directory for managed tables. Its recommended that MANAGEDLOCATION be within metastore.warehouse.dir so all managed tables have a common root where common governance policies. It can be used with metastore.warehouse.tenant.colocation to have it point to a directory outside the warehouse root directory to have a tenant based common root where quotas and other policies can be set.
