In previous examples we have used words like “sort” and “assign” to communicate the functionality of the modules. The specifications of a module are conveyeDEBT 发表于 2025-3-23 22:36:41

However, no technique is perfect, and it is expected that some of the errors of the earlier phases will finally manifest themselves in the code. This is particularly true because in the earlier phases most of the verification techniques繁重 发表于 2025-3-24 05:52:48
ominant trends are clearly discernible: focus on software processes and object-orientation. A lot more attention is now given to software processes because process improvement is con sidered one of the basic mechanisms for improving quality and productivity.

The system components that the SDM identifies are modules supporting functional abstraction.Condescending 发表于 2025-3-24 10:41:14

Detailed Design,vious examples we have used words like “sort” and “assign” to communicate the functionality of the modules. The specifications of a module are conveyed by our understanding of the phrases that label the modules. In a design document, a more detailed specification is given by explaining in natural language what a module is supposed to do.Commodious 发表于 2025-3-25 01:40:36
