The development process of web information systems nowadays improved a lot
regarding effectiveness and tool support, but still contains many redundant
steps for similar tasks. In order to overcome this, we use a model-driven
approach to specify a web information system in an agile way and generate a
full- edged and runnable application from a set of models. The covered aspects
of the system comprise data structure, page structure including view on data,
page- and workflow within the system as well as overall application structure
and user rights management. Appropriate tooling allows transforming these
models to complete systems and thus gives us opportunity for a lightweight
development process based on models. In this paper, we describe how we approach
the page- and workflow aspect by using activity diagrams as part of the agile
modeling approach MontiWIS. We give an overview of the defined syntax, describe
the supported forms of action contents and finally explain how the behavior is
realized in the generated application.Comment: 12 pages, 6 figure
