Design Elements for UML Diagrams

“Unified Modelling Language” is known to be useful for applying in different spheres of business activity (e.g., internet technologies, finance, banking, aerospace healthcare, etc.), being an accepted standard for modelling any needed systems. There are a few notations you can use for making your “UML diagrams”, being made for visual representation of any needed requirements, subsystems, both logical and physical elements as well as structural and behavioural patterns. Being standardized as well as “general-purpose” language, Unified Modelling one is very popular, especially in software engineering, including a set of the graphic notation techniques to use them for creating different visual models of software-intensive as well as object-oriented systems. There are thirteen types of Unified Modelling Language diagrams, all of which you can create within ConceptDraw PRO software. Having it means being able to finish with a final result within only a few hours or minutes, getting a great as well as smart looking diagrams in the end. The mentioned types of UML diagrams, that can be always created with a use of ConceptDraw PRO as well as the solution from ConceptDraw STORE, are: “class” (also known as “package”), “sequence”, “collaboration”, “use case”, “object”, “component”, “activity”, “state machine”, “deployment”, “composite structure”, “timing” and “interaction overview” UML diagrams. Some of the described types of Unified Modelling Language will be described later in this article.

Thus, in software engineering a class diagram is quite often used within the Unified Modelling Language), being one of the types of static structure diagrams that describe the structure of a system in a way of showing the system's classes, their attributes, the relationships among objects as well as the operations. Such class diagrams are the main building blocks of object-oriented modelling, being used both for detailed modelling translating the models into the programming code and for general so called “conceptual modelling” of the systematics of any needed application to apply them to. These class diagrams can also be used for data modelling, having the “classes” representing both the main elements, the classes to be programmed as well as the interactions within the appropriate application.

In this type of diagram, classes are usually represented in a way of boxes containing three compartments: the name of the class, the attributes of the class and the operations the class can execute. Some classes can be identified as well as grouped together in a class diagram helping to determine the static relations between them. Being busy with detailed modelling, you can always split the classes of the conceptual design into a number of subclasses while creating any needed class diagram using ConceptDraw PRO software. UML state machine diagram can be also created with help of ConceptDraw PRO diagramming application, being also known as so called “UML state-chart”. It is simply an enhanced realization of the mathematical concept of a “finite automaton”, being a mathematical model of computation – an abstract machine, being one of a finite number of states at any given time, widely used in computer science applications within the UML notation. The main reason for using such kind of diagrams is to organize the way some computer program, device or other technical process works.

The goal for using the UML state machines is to overcome the main limitations of so called traditional “finite-state machines” while retaining their main benefits, as UML state-charts introduce the new concepts of orthogonal regions and hierarchically nested states, while extending the notion of actions, having the characteristics of both Moore machines and Mealy ones, supporting actions, which depend on both the triggering event and state of the system.

The term "UML state machine" can also be referred to two kinds of state machines, which are protocol state machines and behavioural state machines. The last mentioned can be used to model the behaviour of some individual entities, such as class instances, for example. At the same time protocol state machines are usually used for expressing usage protocols, being used for specifying the legal usage scenarios of classifiers, ports and interfaces.

It’s case it’s needed, you can always create any of the previously mentioned as well as described above “Unified Modelling Language diagrams” with help of ConceptDraw PRO software, using the application ConceptDraw STORE as it is the one where you can find the needed solutions, full of the pre-made examples of such UML diagrams and stencil libraries, where you can get the design symbols from. Downloading the ConceptDraw PRO application mean taking a first step towards getting a very smart and professional result, whether you need a diagram to be created or some other drawing, such as charts, flowcharts, map or scheme. It is also always beneficial to have ConceptDraw STORE application, as it was mentioned before, as this new product of “CS Odessa” allows all ConceptDraw PRO users to download any needed solution they need for making their flowcharts, maps, charts, schemes, plans, and diagrams, including the UML ones.

If you think of making a “class”, “sequence”, “use case”, “collaboration”, “object”, “component”, “state machine”, “activity”, “deployment”, “timing”, “interaction overview” or “composite structure” UML diagram, then you can always open ConceptDraw PRO application and using the “Rapid UML” solution from ConceptDraw STORE, which will enable you to make any of the Unified Modelling Language diagrams, described before. Having this solution means having an opportunity to use the pre-made samples and templates from it and so to simplify your work of creating great looking as well as simply professionally looking diagrams in ConceptDraw PRO software.


UML Diagrams — Design Elements


UML 2.4 diagrams represent two different views of a system model:

  • Static (or structural) view: emphasizes the static structure of the system using objects, attributes, operations and relationships. The structural view includes class diagrams, component diagrams, composite structure diagrams, deployment diagrams, object diagrams, package diagrams, profile diagrams.
  • Dynamic (or behavioral) view: emphasizes the dynamic behavior of the system by showing collaborations among objects and changes to the internal states of objects. This view includes activity diagrams, communication diagrams, interaction overview diagram, sequence diagrams, state machine diagrams, timing diagrams, use case diagrams.
    [Unified Modeling Language. Wikipedia]

The Rapid UML solution from Software Development area of ConceptDraw Solution Park includes 13 vector stencils libraries for drawing the UML 2.4 diagrams using ConceptDraw PRO diagramming and vector drawing software.


Component Diagrams

"In the Unified Modeling Language, a component diagram depicts how components are wired together to form larger components and or software systems. They are used to illustrate the structure of arbitrarily complex systems."
[Component diagram. Wikipedia]


Component Diagram


Activity Diagrams

"Activity diagrams are graphical representations of workflows of stepwise activities and actions with support for choice, iteration and concurrency. In the Unified Modeling Language, activity diagrams are intended to model both computational and organisational processes (i.e. workflows). Activity diagrams show the overall flow of control."
[Activity diagram. Wikipedia]


Activity Diagram


Use Case Diagrams

"A use case diagram at its simplest is a representation of a user's interaction with the system and depicting the specifications of a use case. A use case diagram can portray the different types of users of a system and the various ways that they interact with the system. This type of diagram is typically used in conjunction with the textual use case and will often be accompanied by other types of diagrams as well."
[Use Case Diagram. Wikipedia]


Use Case Diagram


Sequence Diagrams

"A sequence diagram is a interaction diagram that shows how processes operate with one another and in what order. It is a construct of a Message Sequence Chart. A sequence diagram shows object interactions arranged in time sequence. It depicts the objects and classes involved in the scenario and the sequence of messages exchanged between the objects needed to carry out the functionality of the scenario. Sequence diagrams are typically associated with use case realizations in the Logical View of the system under development. Sequence diagrams are sometimes called event diagrams, event scenarios.

A sequence diagram shows, as parallel vertical lines (lifelines), different processes or objects that live simultaneously, and, as horizontal arrows, the messages exchanged between them, in the order in which they occur. This allows the specification of simple runtime scenarios in a graphical manner."
[Sequence diagram. Wikipedia]

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

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 PRO 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 PRO — 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 PRO — 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.business process flowcharts, flowchart symbols, process flow diagram, workflow diagram, flowchart maker
