Use Case Diagram
It takes into account the requirements specification document, and taking as a starting point, it desired to create a global representation showing the functioning of a software system; it desired to include in such representation the interactions between the software system to develop and its actors (either people or external systems).
It takes into account with a UML-based standard that represents the full functionality of a software system satisfying the requirements SpecificationLMS, detailing how the system can be used and by identifying the interactions between the software system and its actors.
It desired to create a representation of functioning of a software system from the user's perspective. Within this representation is desired detail the different types of users and external systems that interact with the software system to be developed. The development group already has the requirements specification document.
- Type of Organization: SMEs, Large Companies.
- System Type: It applies to all types of systems.
- Programming Paradigm: OO (Object Oriented)
- Benefits of using this pattern
- A graphic description of how the software system works and how it will be used is provided.
- It is possible to describe the interactions between the system and its actors.
- It has a representation that is useful to show the client what will be the system's functionality and roles are involved.
- Definition of software requirements (functional and non-functional).
- Notions of UML, especially the technique of modeling of use cases.
