1. A computer-implemented method, comprising: generating, by a computing system, an interactive display of a business network meta model graph that illustrates a business network, the interactive display of the meta model graph including nodes and edges that are displayed between the nodes, wherein each of the nodes represents a real world participant in the business network, and each of the edges represents a real world interaction between two of the participants of the business network, wherein some of the edges are peer to peer message flow edges that represent a direct communication between two of the participants in the business network without a middleware participant between the two participants, some of the edges are integration flow edges that represent a communication between two of the participants in the business network that involved a middleware participant between the two participants, and each of the integration flow edges is displayed with a particular graphical notation that is different than a graphical notation displayed for the peer to peer message flow edges; presenting, by the computing system, the interactive display of the business network from a business application perspective in which each of the participants is identified as being a business entity; presenting, by the computing system, the interactive display of the business network from an information technology perspective in which each of the participants is identified as being an application system; and receiving, by the computing system, user selection of a particular one of the integration flow edges that is shown as connecting a first participant of the participants in the business network to a second participant of the participants in the business network, and as a result causing the particular one of the integration flows to disappear from the display, and instead having the display present one or more middleware participants in connection to the first participant and the second participant with one or more of the peer to peer message flow edges.
