Research On Software Process Modeling Technology

China's emerging software development firms by the software development technology continues to mature,but its software development process management software company with international lags far behind,this appearance is largely due to the process of construction of China's software model to fall behind technologically. Is therefore necessary to examine a set of software development suited to China's enterprises software process model in order to improve its software R & D management level, and enhance their competitiveness.Software process model is a kind of abstract description for the information such as the activities,products, resources,constraints,personnel information in the software development process.In the support of distributed DDS-oriented architecture,the article is on the research of software process modeling technology for the described elements needed in the software process modeling. The thesis abstracts the model of process modeling by analyzing the relation between the meta model of process modeling and the domain model under the environment of oriented to Distributed Denial of Service architecture.This paper also defines the formalization of domain model and describes the relationship of domain model using object constraint language.In terms of the process modeling methods,this paper presents a kind of activity-based modeling method,which can define a phase of implementation steps and principles of ending,thus reduce the complexity of the system model design.By analyzing the relationship between entities of the activity-based modeling approach, this paper reaches a solution about the functional relationship of activities,tasks and functions.This paper gives an example of modeling process whick combine this modeling method with SysML language.Through the constraints and cooperative relations between the domain models,this paper raised three validation rules:being consistency verification,matching consistency checking and mapping completeness validation.According to an instance to verification of the completeness of maps.Finally,this paper introduced the function of the IDP platform which is based on the distributed DDS architecture and described GEF framework based on MVC pattern and its implementation,this paper design the activities of the process model system.
