Reverse engineering Web applications: the WARE approach

ones. For example, a use case exclusively included by another one will be grouped with it to provide a more abstract use case belonging to a higher level use case diagram. As for the UML sequence diagrams abstraction, for each use case (i.e. validated cluster) it is possible to produce a sequence diagram whose objects derive from classes associated with the cluster’s entities, while interactions among objects can be deduced both from the relationships between classes in the class diagram and from the results of the dynamic analysis. Dynamic analysis results are indispensable in order to deduce the sequence of messages exchanged between entities involved in a given relationship. Each message exchange will be associated with a label indicating the corresponding action type (such as load, build, submit, etc.), and may have a list of parameters deduced by analysing the data flow between interconnected items in the Web application.
