Method for communicating data requests to one or more data sources and for processing requested data from one or more data sources in an application

A computing unit configured to communicate data requests to one or more data sources, the computing unit configured to:

• receive a data request, with which data of one or more data types are requested, from an application;
• check availability of one or more data sources that are able to provide the one or more requested data types;
• send, based on at least one of the one or more data sources being available, a request to each available data source for the requested associated data type that the data source can provide;
• and
• send, based on no data source being available for at least one of the requested data types, a request for the data type to a placeholder module.

A non-transitory machine-readable storage medium on which is stored a computer program for communicating data requests to one or more data sources, the computer program, when executed by a computer, causing the computer to perform the following steps:

• receiving a data request, with which data of one or more data types are requested, from an application;
• checking availability of one or more data sources that are able to provide the one or more requested data types;
• sending, based on at least one of the one or more data sources being available, a request to each available data source for the requested associated data type that the data source can provide;
• and
• sending, based on no data source being available for at least one of the requested data types, a request for the data type to a placeholder module.
