Probably the most well-known diagrams of UML are the Use Case examples.

Look how easy it is to create a UML Use Case diagram using the Help.

  • Go to the Visual Designer.
  • Put some use cases, actors, and functions onto the default opened visualization canvas.
  • Enter some names for the use cases, actors, and functions, and save your UML use case diagram.
  • Click on the share link for the Viewer, paste it into your email, and email it to anyone to share it or add it to your ePortfolio.
  • You have successfully created and shared your first use case example on the Dragon1 software platform as your UML Creator.

But why is it smart to create a dynamic online UML diagram, to take decisions with UML diagrams, and how does creating diagrams in UML work on Dragon1?

Creating UML Diagrams has been made very easy to do on the Dragon1 platform. Even without any knowledge of the UML Language, you will be able to create a use case diagram or class diagram in no time.

Dragon1 is a specialized UML Tool online consisting of several web applications. One of them is the Visual Designer. This web application provides you with symbols and templates to quickly create UML Diagrams and store them manageable in a repository (database).

Dragon1 offers you various things when creating diagrams in UML. You can import-export files and regenerate an online UML diagram very quickly.

You can choose to diagram with modeling rules enforced or to do the diagram-type compliance checking afterward. You can choose what suits your way of modeling best.

Also, a unique aspect of Dragon1 is that you can generate different views of your UML Diagrams using different icons and images and different layouts and data filters.

Some stakeholders just need diagrams to use pictures, icons, and images they like or understand instead of the wireframe shapes of the UML standards. Also, some stakeholders are distracted if the wrong or topic data is shown, with a data filter you can tune the diagram for a stakeholder on a need-to-see basis. Dragon1 gives you this freedom.

Dragon1 is online Enterprise Architecture Software, that specializes in creating diagrams in UML, to increase your productivity. Read here more about Dragon1 Modeling Language.

One of the oldest and most complete diagrams from Euclid's Elements of Geometry is a fragment of papyrus. Around 300 A.D.

If a straight line is cut into equal and unequal segments, the rectangle contained by the unequal segments of the whole together with the square on the straight line between the points of the section is equal to the square on the half.

About UML

UML stands for Unified Modeling Language and is managed by OMG (Object Management Group) UML is a powerful language that can be used to model organizations, businesses, information systems, applications, software, and technology. All with some limitations and of course your knowledge about the topic you are modeling, to get the most out of UML.

There are a lot of UML Tools available in the world, but on the Dragon1 Enterprise Architecture platform with its specific UML Tool, you can create UML diagrams with popups, sounds, tracking, and tracing and you can click through to other interactive diagrams or project documentation. Purchase here your Dragon1 PRO user license and start with your first interactive UML diagram.

What is a Diagram?

A diagram is a symbolic representation of information according to a certain visualization technique.

A diagram is a formal representation as opposed to a drawing, which is an informal representation.

A diagram is a special type of drawing in the sense that it explains how a system is or should be built up or behaves. Therefore a diagram shows your relationships, interdependencies, and flows of information between the parts or elements of a system. The system in the context of a diagram can be anything, from an organization to a business process, software application, or even a human body.

Diagrams have been used since ancient times but became more prevalent during the Enlightenment. Read more on Wikipedia about the Unified Modeling Language. The words model and graph are often used as synonyms for diagrams.

Because diagrams are high-value and high-quality drawings, people rely on them, for instance in science with mathematical diagrams.

Why are UML Diagrams important for an Organization?

Not only diagramming but especially creating diagrams in UML is important for any organization. By creating UML Diagrams the stakeholders of the organization (investors, management, clients, and employees) get to know how solid and sound the current structures and solutions of the organization are. Where there might be an innovation-blocking aspect and how future structures and solutions must be built and constructed to enable business changes.

In short: with UML Diagrams you can do analyses and design business processes and software applications.

Because UML is the internal standard by huge numbers of people modeling processes and software with UML, it is a very wise investment for an organization. There are hundreds of thousands of people capable of creating UML diagrams and any diagram created in UML can be read and used by hundreds of thousands of people. Suppliers and Clients can collaborate very well via UML diagrams.

Maybe the biggest benefit of the UML diagram is that you can compare your situation from that with the situation in other organizations or with benchmarks. There are so many UML diagrams available in the world, that for any topic hundreds of UML reference diagrams and examples are available.

And Why for Business Professionals?

If you are a business professional you will significantly increase your chances of being a successful business process designer or software architect if you master the Unified Modeling Language.

For instance, in all the Fortune 500 companies UML is used by at least one person.

Creating UML Diagrams together with your colleagues also has benefits. The discussions you will have are more about the content of the diagram instead of discussing how to model it. In this way, UML as a standard not only makes your work more efficient but also makes the whole work much more efficient.
