Layer Expansion of Use Case Based on Tree
Xiaohui Cheng · Journal of Guilin University of Technology · 2007
Coarsely granular use case modeling can′t meet the development of large scale software system.UML can not provide a proper detailed method on use case.A tree-based layered expansion of use cases analyses is introduced,which can help use cases thinner and more detailed.The relationships between use cases,such asincludeorextend,are not able to illustrate the new relationship between use case and the new one.Therefore,a new relationship between use cases is put forward to make use cases more detailed.
