  First we shortly review the different kinds of network modelling methods for
systems biology with an emphasis on the different subtypes of logical models,
which we review in more detail. Then we show the advantages of Boolean networks
models over more mechanistic modelling types like differential equation
techniques. Then follows an overlook about connections between different kinds
of models and how they can be converted to each other. We also give a short
overview about the mathematical frameworks for modelling of logical networks
and list available software packages for logical modelling. Then we give an
overview about the available standards and ontologies for storing such logical
systems biology models and their results. In the end we give a short review
about the difference between quantitative and qualitative models and describe
the mathematics that specifically deals with qualitative modelling.
