How many types of diagrams are there in uml

A conceptual model is made up of various concepts which are interrelated. It helps us to understand. A conceptual model is required in UML. You have to understand the entities and relationships between them before actually modeling the system. It is a pictorial representation of classes, objects, and relationships between them. UML diagram is a model that describes a part of a system.

It is used to define the functionality or a design of a system. A diagram must be clear and concise so that the viewer will readily understand it. Structural diagrams are used to represent a static view of a system.

It represents a part of a system that makes up the structure of a system. A structural diagram shows various objects within the system. Any real-world system can be represented in either a static form or a dynamic form. A system is said to be complete if it is expressed in both the static and dynamic ways. The behavioral diagram represents the functioning of a system. UML diagrams that deals with the static part of a system are called structural diagrams.

UML diagrams that deals with the moving or dynamic parts of the system are called behavioral diagrams. Interaction diagram is nothing but a subset of behavioral diagrams. It is used to visualize the flow between various use case elements of a system.

Interaction diagrams are used to show an interaction between two entities and how data flows within them. There are many tools available in the market to generate UML diagrams. Some are desktop based while others can be used online. Following is a curated list of tools which can be used for the creation of UML models:.

According to your PC specifications. These nodes are physical entities where the components are deployed. Deployment diagrams are used for visualizing the deployment view of a system.

This is generally used by the deployment team. Component diagrams are dependent upon the classes, interfaces, etc. Again, the deployment diagram is dependent upon the components, which are used to make component diagrams. Any system can have two aspects, static and dynamic. So, a model is considered as complete when both the aspects are fully covered. Behavioral diagrams basically capture the dynamic aspect of a system. Use case diagrams are a set of use cases, actors, and their relationships.

They represent the use case view of a system. A use case represents a particular functionality of a system. These controllers are known as actors.

A sequence diagram is an interaction diagram. From the name, it is clear that the diagram deals with some sequences, which are the sequence of messages flowing from one object to another. Interaction among the components of a system is very important from implementation and execution perspective. Sequence diagram is used to visualize the sequence of calls in a system to perform a specific functionality.

Collaboration diagram is another form of interaction diagram. Structural organization consists of objects and links. The purpose of collaboration diagram is similar to sequence diagram.

However, the specific purpose of collaboration diagram is to visualize the organization of objects and their interaction.

These events are responsible for state change of the system. Statechart diagram is used to represent the event driven state change of a system. It basically describes the state change of a class, interface, etc. This article also provides you with an image map for quickly visiting to a series of "What is UML Diagram"papers Just click the boxes of UML diagram in the image map above.
