How to create UML diagrams in MS Visio?

 UML diagrams are used to represent how actors are related in a system, just like an application for a computer program. Actor may be a person, an Organization, or any system. These diagrams demonstrate the Framework's behaviour. It is not mandatory that tin the order of display they are performed they will appear. This sets out what needs to be considered depending on the device capacity. Depending on the boundaries of the structure it decides what needs to be considered outside or inside the framework. An object can play a few parts and is thus portrayed by a couple of actors. Association outlines the actor's role within the use case. A use case represents a set of events that occur when an individual uses a program to finish an operation. A use case is typically a fairly extensive process, and not a single stage or transaction.

 Follow the steps below to build UML diagrams,

Once you open the MS Visio application, in the file tab, select New.

Just Input UML in the Search box and select appropriate from the results.

Choose a blank template or an appropriate template.

Choose a metric unit or US unit at that point.

Choose the option of Create, Drawing screen will open.

You can see the Shapes window; a UML case stencil is opened.

Include appropriate shape(s) to the Drawing page.

Add a subsystem which will represent an entire structure or an important component.

Add a case diagram with a subsystem.

Add Actors to the Diagram

Add Connectors to the shapes as per the Process flow.

There are different connectors available. They are,

Association- Denotes the actor's connection with a case.

Dependency-Denotes the dependency involved with other cases.

Generalization-It demonstrates that use cases can be a specific way of achieving common use objectives.

Include — Denotes how an application case breaks in small steps.

Extend-Denotes the usage of case adds to functionality.
