vif-devel Mailing List for VIF

Hello

Here's the description and specification of the next use case (Use Case 12,
see http://vif.sourceforge.net/RequirementsAndSchdule.html).

The use case starts after the group administrator logged into the VIF
administration application. The list of discussion groups the administrator
is administering is displayed. The group administrator selects one that is
created but doesn't have a starting question yet. Text fields for the
starting question and for additional explanations are displayed in a form.
The group administrator enters the starting question and additional
information and submits the form. The system saves the information and
creates a unique decimal identification for the contribution.
There's no workflow needed at this point since the group administrator has
the right to publish contributions immediately and without review.

The information submitted by the group administrator is added in the tables
tblQuestion (for the starting question) and tblContribution (for additional
information) (see Datamodel). Each discussion group consists of various
questions, which have to be linked to the group by the table
tblLinkGroupQuestion. Each question can be accompanied by various
contributions, i.e. explaining information. Therefore, the table
tblLinkContributionQuestion links contributions to their questions. Each
essential information has to be historised so that changes can be traced
back and rolled back. Therefore we need two additional tables
tblQuestionHistory and tblContributionHistory.

Therefore, the implementation of this use case consists of the following
steps:
a) Model: Create the interfaces for the domain objects Question,
QuestionHistory, Contribution, ContributionHistory, LinkGroupQuestion,
LinkContributionQuestion and their homes QuestionHome, ContributionHome etc.
After creating the interfaces, the implementations QuestionImpl,
QuestionHomeImpl, ContributionImpl, ContributionHomeImpl etc. have to be
created. The implementations of existing domain objects can be taken as
examples.
b) Controller: Create the tasks AdminContributionShowTask and
AdminContributionSaveTask. The first task controls the display of the form,
the second saves the data submitted by the group administrator. Note: The
newly created tasks have to be registered to TaskManagerImpl.
c) View: Create the views (Java classes and XSLT). The Java views prepare
the produced XML for that they can be transformed by the appropriate XSLT
files.
