BPMN And Business Process Management - Introduction to the New Business Process Modeling Standard
BPMN consists of one diagram - called the Business Process Diagram (BPD). The BPMN Business Process Diagram has been designed to be easy to use and understand, but also provides the ability to model complex business processes. It has also been designed specifically with web services in mind. BPMN is only one of three specifications that the BPMI has developed - the other two are a Business Process Modeling Language (BPML) and a Business Process Query Language (BPQL).
All have been developed using a solid mathematical foundation, which enables a BPMN Business Process Diagram to map directly to BPML, in the same way that a physical data model maps directly to Data Definition Language (DDL).
There are competing standards to BPML, chief among them is the Business Process Execution Language For Web Services (BPEL4WS) created in a joint venture by BEA, IBM, Microsoft, and others. However, BPMI has created BPMN so that it maps readily to any business process execution language.
BPMN provides a number of advantages to modeling business processes over the Unified Modeling Language (UML). First, it offers a process flow modeling technique that is more conducive to the way business analysts model. Second, its solid mathematical foundation is expressly designed to map to business execution languages, whereas UML is not. BPMN can map to UML, and provide a solid business modeling front end to systems design with UML.
