According to one general aspect, a method of retrieving data entities from a backend data device may include maintaining a data model of data entities employed by a user interface. The data model may include a hierarchical relationship between a leading data entity and at least one child data entity. The method may also include authorizing, with an authorization device, when retrieving the leading data entity. The method may include instructing the authorization device that data retrievals of subsequent data entities are to be authorized based upon the authorization of the leading data entity. The method may also include retrieving at least one child data entity of the leading data entity without providing additional authorization credentials.
