Modeling languages are specialized languages used to create abstract representations of systems, processes, or structures. They help in visualizing, specifying, and documenting complex systems in a clear and understandable way. Common examples include UML (Unified Modeling Language) for software design and BPMN (Business Process Model and Notation) for business processes. These languages provide a set of symbols and rules that allow users to create diagrams and models that convey information effectively. By using modeling languages, teams can communicate ideas, identify issues, and collaborate more efficiently, ultimately leading to better design and implementation of systems.
