An extension naming approach for avoiding naming collisions in de-normalized view on a business object can include accessing a reference field bundle, which includes reference field(s) corresponding to a core business object defined in a core software platform of a software architecture, from a metadata repository. A user can define an extension to the business object based on the core business object, for example via a development environment. The reference field(s) can include a defined path from a node in a peripheral object to a corresponding node in the core business object. A unique and reproducible name for the extension field can be generated based on the reference field, and the extension field with the unique and reproducible name can be added to the business object and to a data model of the peripheral object.
