Abstract: An enterprise database server may store enterprise information. An application layer server, coupled to the enterprise database server, may use an application programming language (e.g., ABAP) to access the enterprise information. The application layer server may execute a plurality of domain runtimes, each associated with a domain service (e.g., transactional, SQL, analytical, search, etc.). The application layer server may also access, by a first domain runtime, a first data service entity in an infrastructure for data modelling (e.g., CDS) that enables data models to be defined and consumed on the enterprise database server. Similarly, the application layer server may access, by a second domain runtime, a second data service entity in the infrastructure for data modelling. According to some embodiments, the first data service entity includes a first provider contract and the second data service entity includes a second provider contract (different than the first provider contract).

Abstract: A remote drive with a support element for a top-hat-rail mounting. Opposing actuators disposed on the support element alternatingly act on a displaceably mounted slider by rod-shaped anchors. A slider passage receives a first lever arm of a rocker lever pivotable about a rotational axis parallel to the top hat rail length and nearly passes through a rotational point of a shift lever of a switching device. A carrier rail on a second lever arm is parallel to the top hat rail length, the shift lever engaging the carrier rail to the side of the second lever arm. When the slider is displaced, the rocker lever flips simultaneously activate the shift lever. In a remote drive assembly, two remote drives are disposed adjacent to one another on a top hat rail with a locking mechanism. Alternatively, individually controlled actuators act on first and second legs of a T-shaped rocker switch.
