visio use case diagram template

The use case diagram is used to describe the relationship between users, requirements, and system functional units. It shows a system function model diagram that can be observed by external users. [PURPOSE]: help the development team understand the functional requirements of the system in a visual manner. The

Defined system boundaries determine the boundaries between the inside and outside of the system. the protagonist represents the role played by the external object. An object can play several roles, so it can be represented by several protagonists. communication relationships are used to illustrate the participation of protagonists in use cases. A use case is a

During requirement analysis, complex requirements always make it difficult to find out the relationship before the use case. The generalize relationship is easier to find out, and the most confusing is include and extend. Many people on the Internet do not understand this, or even make mistakes. This article tells you how to determine whether to use include or ex

the extension use case adds new behavior to the base use case Diagram Description: Association: Depend on: Generalization: Contains: Extended: Two. Role: Describe the needs of the user (emphasizing the function, the performer of the function, the system in

ArticleDirectory (1) from the perspective of general users (2) From the operator's perspective (3) from the Administrator's perspective Drawing a use case diagram is the first step from the software requirement to the final implementation. Its correctness directly affects the user's satisfaction with the final product. In fact, we can also s

Recently has been learning the basic knowledge of UML, after watching the video, and did not have a good summary, in the process of drawing found a lot of problems, the following is the process of reading their own summary of the UML use case diagram of a little knowledge, share with you. First, the concept A use

control. Describes the performer "Customer" using the "withdraw" use case.The use of connectors (uses connector) can be selective at each endpoint with multiple values, such as showing that a client may only perform one withdrawal transaction at a time. But banks can perform many withdrawal transactions at the same time. The multiplicity setting is set separately on both ends of the purpose connector.Use

The previous blog summarized the use case diagram, in which the relationship between use cases is only included, because the relationship between use cases is not particularly profound. This is also because the UML use

Case modeling is a part of UML modeling and the most basic part of UML. The main function of case modeling is to express the functional requirements or behaviors of the system. To put it bluntly, it is to explain what the system is, so you don't have to worry about how to work. I think the use case chart is the best pi

As mentioned in the previous article on the relationship in the use case diagram, the use case diagram describes user requirements, describes system functions from the user's perspective, and points out the executors of various fu

, the general relationship can be expressed as follows: The above is an article I have referenced. I think the difference between the three relations is very clear. Based on this, I will combine my own system to explain the project (Online Shopping System) as a whole.**************************************** *************************(1) overall system use case diagram
