If several Top-Logic applications and third-party platforms are to communicate with each other in an organization, as well as share information and data, they can be organized through the specific One-Logic model. Top-Logic communicates via BUS interfaces, with which apps can publish or consume data and service information. These BUS interfaces are controlled by the application’s information distribution model. Via suitable configurations in the delivering and receiving application, distributed applications can be created, whereby the inter-app interface is realized purely declaratively via the information distribution models of the participating applications. Distributed data and their linked applications can be fully automated over their complete life cycle from planning, modeling and configuration to application generation and operation, as well as usage. Top-Logic supports the paradigm shift in the digitization of information technology – from automatic application creation to the highly automated orchestration of entire application landscapes.
