Kurzfassung
In retail information systems it is common practice to subsume the
data of products into product groups, which offers organizational
advantages for example when new branches are opened, because they
are assigned product groups instead of single products. Inspired
by this approach, this paper focuses on business processes and
proposes the usage of workflow modules stored in a workflow
warehouse, which represent reusable, standardized components that
are used to build more complex workflow models. In particular, the
paper provides a formal foundation for such compositions in form
of a workflow algebra based on Petri nets, which has similar
operators known from relational algebra in databases. In addition,
the need for a concept of workflow normalization is presented,
which arises during the composition of workflow modules. Finally,
it is shown how the algebra can also be applied in the context of
Web service composition.
