UML Use Case Diagram Example. Social Networking Sites Project

In the early stages of a development project, use case diagrams are used to describe real-world activities and motivations. A use case diagram (use case: In a use case diagram, a representation of a set of events that occurs when an actor uses a system to complete a process. Normally, a use case is a relatively large process, not an individual step or transaction.) is a dynamic or behavior diagram in UML.

Use case diagrams are valuable for visualizing the functional requirements of a system that will translate into design choices and development priorities. You can refine the diagrams in later stages to reflect user interface and design details.

They also help identify any internal or external factors that may influence the system and should be taken into consideration.

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.

NINE RELATED HOW TO's:

Workflow Diagram →

Sometimes it's difficult to find a path in work processes or to understand the requirements, especially when you are a newcomer. To get your thoughts straight, create a workflow diagram, and put everything on it. This will not only help you to get into the workflow, but also show it’s weaknesses. This illustration captures the workflow process of payment an invoice for the electricity consumed by certain enterprise. It was drawn in ConceptDraw DIAGRAM using its solution for Workflow Diagrams. Making a workflow charts means that you need to depict consistently all processes engaged to the workflow process. Then, you should connect them with symbols meaning study and analysis. Next, add symbols of decisions. A work flow diagram made precisely and correctly can help to clarify your work flow to any person.Workflow Diagram *

Data Flow Diagram Model →

Developing a software project supposes architecture first. To make it proper, you can use data flow diagram model in your current project. The data flow diagram represents the Model of small traditional production enterprise that is made using Yourdon and Coad notation. It shows how the data is transfered through a process. According to the notation of Yourdon and Coad a process is represented by circles and data stores are drawn using parallel lines. This DFD was created using the ConceptDraw Data Flow Diagrams solution. Using this solution one can visualize data flow accordingly to the rules of two basic notations used for data flow modeling.Data Flow Diagram Model *
