Systems And Analysis and Design - Case Study Example The next step is to merge the pairs of state-transitions into fragments as well as to put up a state machine diagram together with the states in the right succession. Step four entails looking for simultaneous paths. The last step seeks for extra transitions (Satzinger, Jackson & Burd, 2012). The UML diagram employed to indicate the states and transitions of an object is the state machine diagram. It can be made for any problem domain classes with intricate behavior or for keeping track of status conditions (Satzinger, Jackson & Burd, 2012). The guard-condition is a test or qualifier on the transition and it is a true/false condition that should be satisfied prior to the transition firing. In order for a transition to fire, the trigger must take place, and the guard has to estimate to true (Satzinger, Jackson & Burd, 2012). The domain model class diagram is a particular case. The domain model is essential to recognize all the domain classes needed in the new system. The domain representation is as well used in designing the database. The domain model class diagram and the use case diagram are the major models out of which others get information. The internal descriptions like preconditions, as well as post conditions in these domains, make use of information in the class diagram. These comprehensive depictions are also imperative for making the system sequence diagrams. Consequently, the activity diagrams, in depth descriptions and system sequence diagrams should all be constant regarding the steps of a given use case (Satzinger, Jackson & Burd, 2012). Architectural design is an extensive design of the overall system structure. It is also known as conceptual design or general design. On the other hand, Detail design is a low-level design that entails the design of the explicit program details (Satzinger, Jackson & Burd, 2012). The domain model; generated during systems analysis, is used to
