To develop information processing systems requires effective and efficient communication between many people. In order to understand requirements and design decisions, there is a need for a common conceptual model of the system: one that represents the architecture of the system. Communication between experts from different domains requires a common terminology and notation that is easy to apply. This is where Fundamental Modeling Concepts (FMC) steps in. Primarily FMC is a consistent and coherent way to think and talk about information processing systems. It enables people to communicate the concepts and structures of complex information systems in an efficient way. FMC provides you with a powerful
