摘　　要：UML (Unified Modeling Language) is a visual modeling language used for specifying, visualizing, constructing,and documenting the artifacts of software systems by various diagrams. It has been widely accepted as a standard modeling language in both academic and industrial areas. UML sequence diagrams are mostly used in specifying system requirements. By representing interactions, which are arranged in time sequence,between the objects in a system,sequence diagrams can construct scenarios indicating the system's functions. A UML statechart diagram is a graph shows the sequences of states that an object or an interaction goes through during its life in response to received stimuli,together with its responses and actions. It's useful in the design stage of system development. This essay discusses the computer-aided transformation from sequence diagrams to statechart diagrams,which can offer strong support for the transfering from requirement analysis to system design in the software development process. With OCL (Object Control Language) semantic constrain,a transform algorithm is provided in the paper. And the differences with the related works are also mentioned.UML (Unified Modeling Language) is a visual modeling language used for specifying, visualizing, constructing, and documenting the artifacts of software systems by various diagrams.
