A Process-Aware Information System (PAIS) is a software system driven by explicit Business Process (BP) models. A basic PAIS provides at least an execution engine, a Business Process Modeling Language (BPML) and a graphical editor. The editor is mainly used to design new BP models, maintain existing ones and check their correctness. BPMLs typically embrace an unstructured control-flow paradigm that allows one to create a BP model by connecting the available elements without following any specific construction pattern.
