Abstract: Embodiments relate to manipulating a multi-tenant database, wherein the multi-tenant database comprises one or more source databases for storing tenant data. An aspect includes receiving a database operation request for one or more tenant-specific logic views, wherein the tenant-specific logic views are created for respective tenants based on mapping information pointing to the one or more source databases included in the multi-tenant database and multi-tenant metadata. Another aspect includes acquiring the mapping information related to the database operation request and pointing to the one or more source databases included in the multi-tenant database. Yet another aspect includes performing a database operation corresponding to the database operation requested for the one or more source databases based on the acquired mapping information.
