Software applications are developed to model complex business processes. These diagrams are used to describe the physical components (hardware), their distribution, and association.ĭeployment diagrams can be visualized as the hardware components/nodes on which the software components reside. Where to Use Deployment Diagrams?ĭeployment diagrams are mainly used by system engineers. The following deployment diagram has been drawn considering all the points mentioned above. The control flows from the caching server to the clustered environment. The user connects to the application using the Internet. The application is assumed to be a web-based application, which is deployed in a clusteredĮnvironment using server 1, server 2, and server 3. An efficient deployment diagram is very important as it controls the following parameters −īefore drawing a deployment diagram, the following artifacts should be identified −įollowing is a sample deployment diagram to provide an idea of the deployment view of order management system. Nodes are nothing but physicalĭeployment diagrams are useful for system engineers. It is related to the component diagram because the components are deployed using the deployment diagrams. Visualize the hardware topology of a system.ĭescribe the hardware components used to deploy software components.ĭeployment diagram represents the deployment view of a system. The purpose of deployment diagrams can be described as − Deployment diagrams are used by the system engineers. Most of the UML diagrams are used to handle logical components but deployment diagrams are made to focus on the hardware topology of a system. However, these two diagrams are special diagrams used to focus on software and hardware components. UML is mainly designed to focus on the software artifacts of a system. Component diagrams and deployment diagrams are closely related.Ĭomponent diagrams are used to describe the components and deployment diagrams shows how they are deployed in hardware. Deployment diagrams are used for describing the hardware components, where software components are deployed. The term Deployment itself describes the purpose of the diagram. Deployment diagrams consist of nodes and their relationships. Just Select Association, Click on Admin, and Drag it to the Use Case which you need to connect.Īs I have explained the steps to draw a Use Case Diagram for Online Shopping in Star UML, by adding the Use Case Subject, Actors, Use Cases, And connecting the Actors with the Use Cases.Deployment diagrams are used to visualize the topology of the physical components of a system, where the software components are deployed.ĭeployment diagrams are used to describe the static deployment view of a system. User Will Register, View Item, Make Order, Make Payments, and change Password.Admin will Add Item, Add Category, Manage Item, Manage Order, Manage Registration.Admin will manage login as well as user will Use it.✦ Connect Admin and User with the Use Cases with Association: Last Use Case is Change Password, as the user can go to His/Her Account and Change its password if they want. The ninth Use Case is when the User Makes an Order, then He/She will Make Payments. After Viewing the Item, there comes the Eight Use Case which is Make Order. Seventh Use Case, View Item will be connected with User, as He/She will view the item and then proceed further to purchase. The Sixth Use Case is, Registration is part of a User because without signing up for an Online Shopping System User cannot do other activities. The fifth Use Case is Manage Order which is also managed by an Admin. The fourth Use Case is Manage Item, as adding items is the responsibility of an Admin so Managing Item is also part of Admin. The third Use Case is Add Category which will also be managed by the Admin. The second Use Case is to Add Itemthat will be done by the Admin that needs to be taken care of. So, Select Use Case from the left and add it inside the Use Case Subject. As User will First Login and then He/She can proceed to order something. The first use case that is important for an Online Shopping System is Login. You can also change the Actors Line Color by Right Click -> Line Color. On the left side, pick the Actor Use case and just click wherever you want to add and change its name. So For Online Shopping, There are basically two Actors: Just click on it and Then Make it on the White Side and Give it the name Online Shopping System. The first step to draw a Use Case Diagram for Online Shopping is to Add a Use Case Subject From the left. Step 3: Draw a Use Case Diagram ✦ Add Use Case Subject: You can see on the left side all the use cases of the Use Case Diagram is shown and a whiteboard on the right side. Now you need to add a Diagram from Models -> Add Diagram -> Use Case Diagram. After Downloading, open Star UML and you can see a Blank View.
