Model
Models are a collection of objects and connections. In this respect, models are graphic representatives of processes, structures, data, etc. of a company. Models, objects and connections are detailed by attributes. While objects represent activities, states, data, etc., connections represent how objects relate to each other.
Models are based on model types that specify certain rules, such as which connections are allowed between objects and thus, how they relate to each other.
Model type
Template for models that defines which objects a model can contain and how these objects relate to other objects. It defines the context in which the derived models are relevant.
The model type Event-driven process chain, for example, defines the context Process because the objects it contains reflect the sequence of states, activities, and changed states, among other things. In contrast, models derived from the model type Organizational chart are located in the context Organization; they visualize the organizational structure of a company, for example, which organizational units exist, how organizational units are linked hierarchically, who manages the organizational units, and who is assigned to them.
