UML Use Case Diagram Example. Registration System

The use case diagram (behavior scenarios, precedents) is the initial conceptual representation of the system during its design and development. This diagram consists of actors, use cases and relationships between them. When constructing a diagram, common notation elements can also be used: notes and extension mechanisms.

This sample was created in ConceptDraw DIAGRAM diagramming and vector drawing software using the UML Use Case Diagram library of the Rapid UML Solution from the Software Development area of ConceptDraw Solution Park.
This sample shows the types of user’s interactions with the system and is used at the registration and working with the database system.

Data Flow Diagram Symbols. DFD Library

Data Flow Diagrams show information transfers and process steps of a system. The general concept is an approach of a depicting how occurs input in a system, further processes and what runs out. The aim of DFD is in accomplishing of understanding between developers and users. Data flow diagrams are maintained with other methods of structured systems analysis.

UML Class Diagrams. Diagramming Software for Design UML Diagrams

In software engineering, a UML Class Diagrams is a type of static structure diagram that is used both for general conceptual modeling of the systematics of the application, and for detailed modeling translating the models into programming code.
Use ConceptDraw DIAGRAM with UML class diagram templates, samples and stencil library from Rapid UML solution to show the classes of system, their attributes, operations or methods, and the relationships among the classes.

UML Use Case Diagram Example. Social Networking Sites Project

UML Diagrams Social Networking Sites Project. This sample was created in ConceptDraw DIAGRAM diagramming and vector drawing software using the UML Use Case Diagram library of the Rapid UML Solution from the Software Development area of ConceptDraw Solution Park.
This sample shows the Facebook Socio-health system and is used at the projection and creating of the social networking sites.

Financial Trade UML Use Case Diagram Example

This sample represents the actors, use cases and dependencies between them, and also the relationships between use cases. There are used dependency and use case generalization associations on this UML diagram. Use case generalization is used when you have two similar use cases, but one of them does more than another.
This sample shows the work of the Financial Trade sphere and can be used by trading companies, commercial organizations, traders, different exchanges.

UML Use Case Diagrams

ConceptDraw has several examples that help you to start using software for designing UML Use Case Diagrams.

Interaction Overview Diagram

UML Interaction Overview Diagram schematically shows a control flow with nodes and a sequence of activities that can contain interaction or sequence diagrams.

UML Class Diagram Generalization Example UML Diagrams

This sample was created in ConceptDraw DIAGRAM diagramming and vector drawing software using the UML Class Diagram library of the Rapid UML Solution from the Software Development area of ConceptDraw Solution Park.
This sample describes the use of the classes, the generalization associations between them, the multiplicity of associations and constraints. Provided UML diagram is one of the examples set that are part of Rapid UML solution.

UML Deployment Diagram Example - ATM System UML diagrams

This sample was created in ConceptDraw DIAGRAM diagramming and vector drawing software using the UML Deployment Diagram library of the Rapid UML Solution from the Software Development area of ConceptDraw Solution Park.
This sample shows the work of the ATM (Automated Teller Machine) banking system that is used for service and performing of the banking transactions using ATMs. System engineers can use comprehensive UML diagrams solution.

UML Use Case Diagram. Design Elements

UML Use Case Diagrams are used to illustrate the structure of arbitrarily complex systems and illustrates the service consumer - service provider relationship between components.
