UML Model Shapes
Activity in Unified Modeling Language (UML) is a major task that must take place in order to fulfill an operation contract.
State defines current condition of an event or activity. State diagram is ofen used to describe state changes triggered by events.
Decision activity were introduced in UML to support conditionals in activities. A decision activity is modeled as a diamond on a UML Activity diagram. Decision activity should reflect the previous activity.
Control flow in computer science refers to the order in which the individual statements, instructions or function calls of an imperative or a declarative program are executed or evaluated. Object flow is a path along which objects or data can pass.
Object flow is a path along which objects or data can pass.
Bars represent the start (split) or end (join) of concurrent activities.
Initial state shows the initial state of the workflow, meanwhile, final state displays the final state of the workflow.
Constraint is an extension mechanism that enables you to refine the semantics of a UML model element.
Classes and interfaces in UML shows architecture and features of the designed system.
Aggregation is a special type of association in which objects are assembled or configured together to create a more complex object. An aggregation describes a group of objects and how you interact with them.
Dependency relationship is a relationship in which one element, the client, uses or depends on another element, the supplier.
Association is a relationship between two classifiers, such as classes or use cases, that describes the reasons for the relationship and the rules that govern the relationship.
Package in the Unified Modeling Language is used "to group elements, and to provide a namespace for the grouped elements.
Objects are model elements that represent instances of a class or of classes.
Data flow is one kind of data driven architecture which explains how data is processed and transferred in a system.
Lifeline represents each instance in an interaction.
Message is an element that defines a specific kind of communication between instances in an interaction.
Actor specifies a role played by a user or any other system that interacts with the subject.
