Abstract
General System Theory recognizes a useful distinction in modelling the functionality and structure of the systems. Both concepts are applied tradionally in the development of Software Systems. The aim of this paper is to show the homogeneity between the functioning and the structure in a system and metasystem level in the MEDES software development method. Moreover, we will show how the management of the structural and functional histories can be carried out in a similar way allowing the realization of the necessary queries required in the evaluation of preconditions over the actions. In order to do that we define two kinds of queries (temporal and general queries) and we distinguish between the expressions that must be evaluated and their results. In order to manage these queries in an homogeneous way we have designed an object-oriented hierarchical structure of classes which can be used at the system and metasystem levels.
