This software is good for people who want to jump right in drawing UML diagrams rather than spending tons of time trying to learn the software. You can create shapes with drag-and-drop, align and layout shapes precisely with alignment guide.
Programming languages may use operations and methods which are basically same, though vary by names and graphical notations. The UML language defines standards not only for operations and methods of programming languages, but also for their terminology.
So, using UML diagrams for visual modeling will help you to improve the final software products, simplify the process of its creation and meet the deadlines.
ConceptDraw DIAGRAM is a professional software product designed for creating detailed UML diagrams. A large number of libraries with ready-made objects for UML diagrams and task-oriented templates let you create UML diagrams of any complexity without effort.
To draw a diagram, just drag the required objects from the corresponding library onto the document page, then connect them with connectors appropriate for diagrams of this type.
There are 8 types of UML diagrams:
Use case diagram:
Diagrams of this type represent a list of operations performed by the system. Such diagrams are also called functional diagrams, as the list of the system's functions is created based on them, in accordance with the specified requirements.
Use case diagrams are used to describe business processes in automated applications and to define requirement for software to be developed. They depict objects from the system and application domain as well as the tasks performed by them.
Pic.1. UML use case diagram
To draw diagrams of this type, use the UML Use Case Diagram library in ConceptDraw DIAGRAM
- UML diagrams of this type serve to analyse the hardware used in system implementations, interaction between the processor and other components. As a rule, such diagrams are used in the beginning of designing to determine the hardware configuration of the system.
Pic.2. UML deployment diagram
Use the UML Deployment Diagram library to create such diagrams in ConceptDraw DIAGRAM
Statechart diagrams serve to model possible states of the objects in the system. They also depict the sequence of actions required for transition between the states.
Pic.3. UML statechart diagram
Use the UML Statechart Diagram library to create such diagrams in ConceptDraw DIAGRAMSame as Statechart diagrams, such diagrams show the states of objects in the system. The difference is that they can also depict forks for transitions from one state to another. These diagrams can be used to describe behavior algorithms of objects. You may also use them to create flow charts.
Pic.4. UML activity diagram
In ConceptDraw DIAGRAM such diagrams are represented in the UML Activity Diagram library.A type of interaction diagram. Sequence diagrams describe a sequence of interactions between objects.
Pic.5. UML sequence diagram
To draw such a diagram, use the UML Sequence Diagram library.A collaboration diagram is also a type of interaction diagram, but unlike sequence diagrams these diagrams instead of the sequence of interactions between objects describe all variants of such interactions, regardless the sequence.
Pic.6. UML collaboration diagram
- They help to create graphical logical models of a system, further used to create the source code for the classes represented on the diagram. UML class diagrams describe relationship between classes and interfaces.
We recommend to create class diagrams using the Booch OOD template from the ConceptDraw STORE.
Pic.7. UML class diagram
On diagrams of this type, also known as module diagrams, classes and objects are distributed by components or modules. This is very convenient for designing large systems which may count hundreds of components.
Pic.8. UML component diagram
Use the UML Component Diagram library for drawing diagrams of this type.All libraries for creating UML diagrams are available inside the ConceptDraw DIAGRAM Templates and samples are located in the Rapid UML section of ConceptDraw STORE.

Easy Uml Tool
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.
When you are trying to design a system or program, you will need a standard way to visualize it which can be used to specify, construct and document the artifacts. A UML modeling tools open source can be used for this purpose. If you require a general purpose development modeling language then you can simply download UML modeling tools from the internet as these free UML modeling tools are easy to use and available for free.
