Abstract:

In view of the lack of full life-cycle management and poor reusability and extensibility of current IT project management systems,this paper proposes a domain model for IT project life cycle management with a design of loosely coupled POJO core domain entities and a dynamic and flexible object combination technology to meet the individual needs or management.Custom label technology is introduced as the technical specifications of page codes.The practical application shows that the framework effectively improves the standardization,reusability and scalability of the system design.
