Many of the most common causes of software project failures are focused on poor communication or lack of communication between "project key stakeholders". When there is a lack of alliances between development agencies and business advocates, it is even more critical. Business people may know that they have a problem to solve, but the development leader receives only a general description of the business requirements and some specific requirements.In the UML modeling language, a "use
Creating a use case diagram is only the basic and simplest step to complete case modeling. The core of case modeling is to write case documents, also known as case conventions or case descriptions. As the name suggests, the use

The UML use case diagram contains three relationships: (include), (extend), and (generalization ).
Overview
The Use Case attempts to summarize the relationship between roles and systems in the use case, and describes the functional requirements of the system, the interaction between roles and systems, and the system response.

If statements process two branches, the if-else-if structure must be used when processing multiple branches. However, if there are many branches, the more nested if statement layers, the program is not only huge but also difficult to understand. therefore, the C language provides a condition selection statement specifically used to process multi-branch structures, called a switch statement or a switch sta
