Analysis of the service
This phase implies that a preliminary study has been carried out and that the
personalized service to be implemented has been identified. It follows the analysis
model of the 2TUP method [ROQ 07] to meet the evolution constraints of the
service. The analysis phase therefore comprises four stages:
- The
capture of functional needs
describes the service to be developed. It
consists of an exhaustive description of the functional and operational needs for the
modeling of behaviors expected of the service. Certain use cases can be specified by
scenarios, in particular through sequence and/or activity unified modeling language
(UML) diagrams.
-
Functional analysis
describes the structure of the service based on functional
needs. It consists of structuring and representing objects of the business domain of
the service through a series of class diagrams. The behavior of the service is then
described using dynamic diagrams (sequence, activity and transition-state
diagrams). It is also in this stage that data models (modeled by class diagrams)
exchanged between the service and the PS are defined.
