....medicine. 7. It is possible to have an surveyable list of selected products on screen and to print this list on paper. Fig. 3 Example of User Requirements As pioneered by the J.S.D. methodology, modelling the real world or domain allows to construct a solid nucleus for a software system [4]. The complexity of most systems is driven by the complexity of the reality that it has to deal with. In addition, statements about the required functionality always have some underlying assumptions about the real world which should be made explicit. On the other hand, there is no sense in ....

....be returned if it has not previously been borrowed. In order to specify this kind of constraints, each object is equipped with a life cycle state variable and a description of allowed sequences of event types. The latter are described by means of a regular expression, a Jackson Structure diagram [15] or a Finite State Machine. From a mathematical point of view, these three techniques are perfectly equivalent. Fig. 19 depicts how sequence, choice (exclusive and exhaustive selection) and iteration are modelled in each of the first three techniques. In this paper we will use any of these ....

....all and only the event types in S A P. The partitioning of the alphabet in creating, modifying and destroying event types imposes a default life cycle which must be respected by the sequence restrictions. GRAPHICAL REPRESENTATION The structure diagram is drawn according to the notations of JSD [11]. In this kind of diagrams a indicates the iteration of a structure and a o indicates an alternative in a selection structure. A in a box symbolizes the do nothing event. Structure diagrams are transformed to regular expressions in the following way: selection is denoted by , sequence ....
