UML Diagram Types List

Types of UML Diagrams

Unified Modeling Language (UML) is a language of graphic description for object modeling in the field of software engineering. UML was created for definition, visualization, designing of software systems. UML is an open standard that uses graphic notations for creating visual models of object-oriented software systems.

Two types of diagrams are used in UML: Structure Diagrams and Behavior Diagrams. Behavior Diagrams represent the processes proceeding in a modeled environment. Structure Diagrams represent the elements that compose the system.

There are seven types of Structure Diagrams that must be present in any modeled system:

The Behavior Diagrams group includes:

The subgroup of Interaction Diagrams controls the flow of control and data, and includes:

Class Diagrams

UML Class Diagram is a type of Structure Diagrams that shows the classes of a system, attributes, operations, and the relationships between them.


Package Diagrams

UML Package Diagram is a type of Structure Diagrams that represents the packages of the model and dependencies between them.


Object Diagrams

UML Object Diagram is a type of Structure Diagrams that shows the objects of the system and attributes, and relations between the objects at a certain moment of time.


Use Case Diagrams

UML Use Case Diagram is a type of Behavior Diagrams that displays the dependencies between the actors and use cases. UML Use Case Diagram displays the system on the conceptual level.

Sequence Diagrams

UML Sequence Diagram is a type of Interaction Diagrams that describes the interactions between objects and classes that are involved in the scenario and the sequence of messages exchanged between them.


Collaboration Diagrams

UML Communication Diagram in UML 2.0 (Collaboration Diagram in UML 1.x) is a type of Interaction Diagrams that displays the interactions of objects using the sequenced messages.


Activity Diagrams

UML Activity Diagram is a type of Behavior Diagrams that graphically describes decomposition of the some activity on the components.


Component Diagrams

UML Component Diagram is a type of Structure Diagrams that shows how components are connected to larger components or software systems, and shows the dependencies among these components.


Deployment Diagrams

UML Deployment Diagram is a type of Structure Diagrams that shows the physical deployment of information generated by the software programs.


State Machine Diagrams

UML State Machine Diagram is a type of Behavior Diagrams that displays the finite state machine with states and state transitions.


Timing Diagrams

UML Timing Diagram in the UML 2.0 is a specific type of Interaction Diagrams that describes the timing constraints. UML Timing Diagrams describes the behaviors of the objects during a certain period of time.


Interaction Overview Diagrams

UML Interaction Overview Diagram is a type of Interaction Diagrams that describes an overview in which the nodes represent interaction diagrams.


Composite Structure Diagrams

UML Composite Structure Diagram is a type of Structure Diagrams that shows the internal structure of a class and the interactions of elements of the internal structure of the class.

Basic Flowchart Symbols and Meaning →

While creating flowcharts and process flow diagrams, you should use special objects to define different statements, so anyone aware of flowcharts can get your scheme right. There is a short and an extended list of basic flowchart symbols and their meaning. Basic flowchart symbols include terminator objects, rectangles for describing steps of a process, diamonds representing appearing conditions and questions and parallelograms to show incoming data. This diagram gives a general review of the standard symbols that are used when creating flowcharts and process flow diagrams. The practice of using a set of standard flowchart symbols was admitted in order to make flowcharts and other process flow diagrams created by any person properly understandable by other people. The flowchart symbols depict different kinds of actions and phases in a process. The sequence of the actions, and the relationships between them are shown by special lines and arrows. There are a large number of flowchart symbols. Which of them can be used in the particular diagram depends on its type. For instance, some symbols used in data flow diagrams usually are not used in the process flowcharts. Business process system use exactly these flowchart symbols.Basic Flowchart Symbols and Meaning

Process Flowchart →

When trying to figure out the nature of the problems occurring within a project, there are many ways to develop such understanding. One of the most common ways to document processes for further improvement is to draw a process flowchart, which depicts the activities of the process arranged in sequential order — this is business process management. ConceptDraw DIAGRAM is business process mapping software with impressive range of productivity features for business process management and classic project management. This business process management software is helpful for many purposes from different payment processes, or manufacturing processes to chemical processes. Business process mapping flowcharts helps clarify the actual workflow of different people engaged in the same process. This samples were made with ConceptDraw DIAGRAM — business process mapping software for flowcharting and used as classic visio alternative because its briefly named "visio for mac" and for windows, this sort of software named the business process management tools. This flowchart diagram shows a process flow of project management. The diagram that is presented here depicts the project life cycle that is basic for the most of project management methods. Breaking a project into phases allows to track it in the proper manner. Through separation on phases, the total workflow of a project is divided into some foreseeable components, thus making it easier to follow the project status. A project life cycle commonly includes: initiation, definition, design, development and implementation phases. Distinguished method to show parallel and interdependent processes, as well as project life cycle relationships. A flowchart diagram is often used as visual guide to project. For instance, it used by marketing project management software for visualizing stages of marketing activities or as project management workflow tools. Created with ConceptDraw DIAGRAM — business process mapping software which is flowcharting visio alternative or shortly its visio for mac, this sort of software platform often named the business process management tools.Process Flowchart

UML Notation →

There are many ways to track the system in a critical situation. To model a system behavior, uml notation is widely used. Usually, an UML diagram consists of elements such as actor and a case. This diagram represents the structure of UML notations. Unified Modeling Language (UML) is used in software engineering to depict graphically the software modeling process. UM Language uses graphic notations for developing models of object-oriented systems. These notations displays requirements, sub-systems, logical and physical elements, etc. We created this diagram using ConceptDraw DIAGRAM reinforced with Rapid UML solution. It can be helpful for students on software engineering, when learning UML.UML Notation *

Components of ER Diagram →

It is easy to recreate any informational system structure using diagrams. There are three main components of any ER diagram: entity, attribute and relationship. Basing on these three components, one can define other, less used elements, such as weak entity or relationship, derived attribute, recursive relationship etc. This is the set of graphic elements of ERD Chen's notation. This ERD notation is used to represent an entity–relationship models. It involves the set of geometric forms: rectangles - depicting entities, ovals - representing attributes and diamonds depicting relationships assigned for first-class objects, that can have relationships and attributes of their own. Connections are displayed with arrowed lines. It is known that the Chen's ERD notation is used to show a detailed view of entities and relationships. ConceptDraw Entity-Relationship Diagram solution from the Software Development section of Solution Park provides the ability to create ERD of database structure for software development purposes using the Chen’s notation elements.Components of ER Diagram *

Data Flow Diagram →

There are many ways to define the flow of information within a system. Structured-systems analysis method often uses data flow diagrams to show data flow, data storages and data processing visualization. These diagrams are easy to develop and quite useful. Here is a dataflow diagram presenting an example of the manufacturing process flow. The oval process shapes represent a process that controls data within the current system. The process may produce data or make some action based on data. Data flows are represented by lines. They show the movement of information through the system. The direction of the data flow is depicted by the arrow. The external entities are shown by rectangles. They represent the external entities interacting with the system. The data store objects (unclosed rectangles) are used to show data bases participating in a process flow.Data Flow Diagram *
