UML Diagrams

The Unified Modeling Language (UML) is a modeling syntax helping you specify, visualize and model the software systems regarding the structure and design.c The latest version of UML is Version 2.0 which consists of thirteen UML diagrams for modeling purposes.

Visual Paradigm provides a suite of products which fully conform to UML 2.0 specification. There are references provided to you to learn more on how to create the UML diagrams with Visual Paradigm’s products.

Use case diagrams are a specialization of Class Diagrams such that the classifiers shown are restricted to being either Actors or Use Cases. Use case diagram is used to show the relationships among actors, systems and use cases.

• Use Case Diagram Notation
• Creating Condition for Extend Relationship
• Use Case Details
• Creating Parent Elements for Classes and Use Cases

Class diagram provides an overview of the target system by describing the objects and classs and their relationships inside the system. It prvoides a wide variety of usage from modeling the domain-specific data structure to detailed design of the target system.

With the support in model sharing, you can reuse the class models in the interaction diagram for modeling the detailed design of the dynamic behaviour.

• Drawing Class with Template Parameter
• Sharing Model between Class Diagram and Sequence Diagram
• Specifying Package Name for Class Diagram
• Using Mouse Gesture to Synchronize Class Diagrams and Entity Relationship Diagrams
• Creating Parent Elements for Classes and Use Cases

Sequence diagram is the most commonly used interaction diagram in UML. It focuses on the message interchange between elements exist in the system based on a time sequence. There are three types of sequence diagrams – System level sequence diagram, Sub-system level sequence diagram and Model-View-Controller (MVC) level sequence diagram. With the advanced visual modeling capability, you can create complex sequence diagram in few clicks.

• Drawing Sequence Diagram with Resource-Centric Interface
• Drawing Sequence Diagram with Real-time Layout
• Using Alternative Combined Fragments in Sequence Diagram
• Editing the Combined Fragment in Sequence Diagram
• Synchronization between Sequence Diagram and Communication Diagram
• Synchronization between System Level Sequence Diagram and Flow of Event
• Defining Guard Condition of a Combined Fragment

Communication diagram is another common used interaction diagram. It focuses on the collaboration of objects rather than the time sequencing. Visual Paradigm’s products support generating communication diagram from sequence diagram and vice versa.

• Synchronization between Sequence Diagram and Communication Diagram

State machine diagram is used to show the state of an entity in regard to various events.

Activity diagram helps to describe the flow of control of the target system, such as exploring the complex business rules and operations, describing the use case and also the business process. It shows the how the involved parties collaborate with each other to complete an operation.

• Creating Branches with Decision Node Using Resource-Centric Interface

Timing diagram shows the behaviour of the object(s) in a given period of time. Timing diagram focuses on the changes among lifelines with respective to time. Visual Paradigm’s products support two styles for presentation, including discrete timing and the general value lifeline style.
