A telecommunication method for accessing data in a cloud database system by a mobile communication device via a digital cellular mobile telecommunication network, said method comprising: initiate on said mobile telecommunication device a request configured to access data organized according to a first database schema in said cloud database system; sending said request from said mobile telecommunication device to said cloud database system via a first transmission channel in said digital cellular mobile telecommunication network; receiving said request in said cloud database system by an interface to said first transmission channel; using, in a first database server node, the received request to generate a first data view of a first instance (ERP1; 104a) of the first database schema in the cloud database system, including referencing, looking-up a first view variant (310a, 410a, 506; ERP_1) being stored in a data table in reference to the mapped request and the first instance of the first database schema, one or more data tables included in the first instance of the first database schema to generate the first data view; and using, in a second database server node, the received request to generate a second data view of a second instance (ERP2; 104b) of the first database schema in the cloud database system, including referencing, looking-up a second view variant (310b, 410b, 510; ERP_2) being stored in a data table in reference to the mapped request and the second instance (ERP_2) of the first database schema, one or more data tables included in the second instance of the first database schema to generate the second data view; receiving a schema defining a third data view; and modifying the third data view based on one of the generated first data view and the generated second data view wherein modifying the third data view includes: determining a dependence between the third data view and one of the generated first data view and the generated second data view based on a look-up in a data table to return one of the first view variant (ERP_1; 506) and the second view variant (ERP_2; 510); and changing the schema defining the third data view to reference one of the generated first data view and the generated second data view based on the determined dependence. initiate on said mobile telecommunication device a request configured to access data organized according to a first database schema in said cloud database system; sending said request from said mobile telecommunication device to said cloud database system via a first transmission channel in said digital cellular mobile telecommunication network; receiving said request in said cloud database system by an interface to said first transmission channel; using, in a first database server node, the received request to generate a first data view of a first instance (ERP1; 104a) of the first database schema in the cloud database system, including referencing, looking-up a first view variant (310a, 410a, 506; ERP_1) being stored in a data table in reference to the mapped request and the first instance of the first database schema, one or more data tables included in the first instance of the first database schema to generate the first data view; and using, in a second database server node, the received request to generate a second data view of a second instance (ERP2; 104b) of the first database schema in the cloud database system, including referencing, looking-up a second view variant (310b, 410b, 510; ERP_2) being stored in a data table in reference to the mapped request and the second instance (ERP_2) of the first database schema, one or more data tables included in the second instance of the first database schema to generate the second data view; receiving a schema defining a third data view; and modifying the third data view based on one of the generated first data view and the generated second data view wherein modifying the third data view includes: determining a dependence between the third data view and one of the generated first data view and the generated second data view based on a look-up in a data table to return one of the first view variant (ERP_1; 506) and the second view variant (ERP_2; 510); and changing the schema defining the third data view to reference one of the generated first data view and the generated second data view based on the determined dependence.
