Softwargon Engineering Exam - Essay ExampleThis is because the sub-system found here involves exchanging of data. The data sub is done where the shared data is stored in a central or repository which faecal matter be accessed by every sub-system. Additionally, each and every subsystem tends to maintain the database and passes the data to various sub-systems.a) the best temper pretending for word processing system is repository model this is because the model offers an efficient way of sharing gargantuan amount of information and data. Additionally, the sub system need not to be associated with the production of data since in that respect is security and back up. Consequently, the sharing model undergoes publication as a schema for repository.b) the appropriate control model for the real time system that control the safety system in a pulverization is abstract machine model. This is because the model will organize the system into a collection of layers with each providing a col lection of services. It also supports the rising development of the subsystems in various layers. When the layer interfaces change, the adjacent layers will be the one to be affected.3. Coupling how much a module in terms of package, class, or mode relies on the other modules. It is better to reduce coupling or minimize the amount that a qualify module will rely on others system modules. Cohesion is how closely the related parameters like the classes, methods, and functionality indoors the method of the module are to other members within the same module. It is better to raise the cohesion as that shows that the module has specific activity and does only that activity (Dorfman & Thayer, 97). Coupling between the modules arises for various reasons, some of which can be desired and others not. A ranked list comprising of the least to the most desirable include the native data coupling, global data coupling, parameter coupling, and subclass coupling. Cohesion can also be ranked from those that are least desirable to those that are most desirable
