Research On The Transformation Method Of UML Model Based On Domain Ontology Requirement Model

Practice has proved that the requirements engineering is the most important part of software engineering.It is generally believed that the requirements engineering activities include:requirement acquisition,requirement modeling,requirement analysis,etc.There are a lot of methods to obtain and model the requirement,among which the Chinese Academy of Sciences Academician Lu Ruqian advocated the knowledge based requirement method is the leading edge of the current domestic requirement engineering field.Although there are many researches of requirement elicitation,and the establishment of the requirement model to guide the actual software development research,among which a lot of research commitment to put forward new requirement analysis and model construction method,and less on these methods and the actual development of the project design document docking.This thesis proposed a set of methods from the information system of enterprise organization ontology model to UML model transformation based on the domain knowledge requirements model.These methods include the transformation from concept instance to UML static diagram(Use Case Diagram,Class Diagram)and the transformation from the Event Flow Model(EFM)to the UML dynamic diagram(State diagram,Activity diagram).1.This thesis presents a method that from domain ontology model of enterprise organization to UML Activity Diagram transformation,the method using ontology model of enterprise organization in the Event Flow Model(EFM).After the analysis of the similarities and differences of EFM and Activity Diagram,this thesis is given a set of transformation rules convert a flow of events as objects are related to the activities of the process,the results can be directly used for drawing the UML activity diagram.2.On the construction of enterprise organization ontology to create a concept instance based,form to analysis the characteristics of enterprise ontology and UML model,this thesis proposed a conversion method from concept instance to UML model elements.By using the enterprise ontology formalization expression,this method convert the enterprise ontology related concepts and the associated to UML primitives and their relations.With the conversion algorithm,the business situation of the requirement provider can be converted to element of the UML Use Case Diagram and the Class Diagram.Conversion results show that the conversion rules generated UML graphics format specification,the process is clear,has a certain guiding significance for the field of demand analysis to guide the follow-up development.
