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
Before we talk about how to build a use case model, what should be paid attention to when building a use case model?
Problems to be noticed in building use case model
To give you a few common problems in building use case models and principles to follow:

Case management is a collaborative process that can define and evaluate cases, define activities, assign and perform work, and monitor execution. A case is an artificial process, a requirement or an interactive service; The human process is the definition, organization, and managemen

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.

1. Introduction to UML
UML (Unified Modeling Language) is a visual modeling language that is well defined, easy to express, powerful, and universally applicable. It integrates new ideas, new methods, and new technologies in the software engineering field. Its scope is not limited to supporting object-oriented analysis and design, but also supporting the entire process of software development starting from requirement analysis. In the system analysis phase, we generally use UML to draw many diagr

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
