Types of UML Diagrams

UML or Unified Modelling Language can be at any time applied in different spheres of business activity, such as finance, internet technologies, banking, healthcare, aerospace and other business activities. This language is an accepted standard and this standard can be used for modelling any needed system. There are lots of notations you can use for making any needed UML diagrams. These notations can be made for visual representation of any needed subsystems, requirements, physical and logical elements, behavioural and structural patterns, as they are especially relevant to the systems built during using a so-called “object-oriented” style.

The Unified Modelling Language (UML) is a standardized and general-purpose language and it is very popular and quite widely used, especially in the field of software engineering in IT. This Unified Modelling Language includes a set of some graphic notation techniques for creating the visual models of object-oriented software-intensive systems. There are thirteen types of such UML diagrams and you can always create any of them in ConceptDraw DIAGRAM software. These types of UML diagrams are: “package” (or “class”), “collaboration”, “object”, “use case”, “sequence”, “component”, “activity”, “deployment” “state machine”, “timing”, “interaction overview” and “composite structure” UML diagrams. Each of the types of Unified Modelling Language will be described later in this article.

Thus, Unified Modelling Language “Class” diagrams are the static structure diagrams, with the help of which you can describe a structure of some system in a way of showing the system's methods, classes, attributes, operations as well as the relationships among the objects within this system. The so-called Unified Modelling Language “Package” diagram can be used in the Unified Modelling Language for a reason of depicting the dependencies between the packages that can make a particular model. The so-called Unified Modelling Language “Object” diagrams are popular for being used in the Unified Modelling Language (UML). Unified Modelling Language “Object” diagrams show a partial or a complete view of a system’s structure within some specific period of time. The so-called Unified Modelling Language “Use Case” diagrams can be the representations of a user's interaction with some system and with their aid you can depict some particular specifications of a use case. The so-called Unified Modelling Language “Sequence” diagrams are also known as interaction diagrams with the help of which it is simpler for you to show the way some particular processes operate with each other and in which order they do it. The UML “Communication” diagrams model the interactions between different parts in terms of sequenced messages. “Communication” diagrams represent the information from “Use Case”, “Class” and “Sequence” diagrams, describing the dynamic behaviour and the static structure of some system. The UML “Activity” diagrams are the representations of the workflows of the actions as well as the activities with an iteration, choice and concurrency. In the Unified Modelling Language “Activity” diagrams there are models of both organisational and computational processes (for example, workflows) represented and this type of UML diagrams in general represents the overall flow of the control. With UML “Component” diagram you can depict the way some system components are wired with each other and so to form the larger components of software systems or software systems themselves. These diagrams are used for illustrating the structure of arbitrarily complex systems. The UML “Deployment” diagrams can be used for modelling the physical deployment of the artifacts on nodes. The nodes with the artifacts appear in a way of boxes and the artifacts in each node appear in a way of the rectangles in these boxes. These nodes can also have sub-nodes and these sub-nodes can appear in a way of the nested boxes. One single node in the UML “Deployment” diagrams can represent a lot of different physical nodes. The UML “State Machine” diagrams can be used for enhancing the mathematical concept of some finite automaton once it is used in some computer science applications. The UML “Timing” diagrams are quite specific and still interaction diagrams. They are used for concentrating on the timing constraints. The UML “Timing” diagrams can be also used for exploring the behaviour of objects within some particular period of time. With the aid of the UML “Interaction Overview” diagram you can illustrate a control flow with nodes which contain the interaction diagrams. The UML “Interaction Overview” diagrams are identical to the “Activity” diagrams and they both visualize a sequence of some activities, although there is a slight difference between them. The UML “Composite Structure” diagrams are similar to the “Static Structure” diagrams and with their help you can show the internal structure of a class so the collaborations, which this structure makes possible. While creating the UML “Composite Structure” diagrams you can include the internal parts, with the help of which the parts of some system can interact with each other.

You can always create any of mentioned and described above Unified Modelling Language diagrams with the aid of ConceptDraw DIAGRAM software. Besides downloading the ConceptDraw DIAGRAM application, it is also beneficial to have ConceptDraw STORE one as well, as this another product of “CS Odessa” allows ConceptDraw DIAGRAM users to download any solution they need for making your charts, flowcharts, maps and diagrams, schemes and plans, as well as any of the mentioned above UML diagrams at any time you need to create them.

“Rapid UML” solution enables you to make any of the Unified Modelling Language diagrams, using so many different examples and templates from this solution for simplifying ConceptDraw DIAGRAM users' work of creating similar great looking diagrams.

UML Diagram

While developing software, it is very important to have a visual model, because it helps to represent the logic and the architecture of an application. Experienced engineers use UML diagrams to denote relationships between classes and their instances. UML is a general language for a set of diagrams like deployment diagrams, object diagrams or use case diagrams. This diagram represents UML class diagram used for a software system development using an object-oriented method. Class diagrams are categorized as static structure diagrams that depict the physical structure of a system. Class diagram divides a software system's structure into "classes". Classes are defined by the methods and variables of objects. UML Class diagram is used to depict relationships and source code dependencies between objects.UML Diagrams
