Learn to Create a UML Diagram in 5 Simple Steps

A UML Diagram is a graphical illustration of any idea that tells you how a system will look in a static form. It helps business managers and programmers brainstorm ideas on how to make it better during the developmental stages of any product. 

A good UML diagram has detailed class structures, well-defined relationships, and visible information. However, creating such a thing can be an exhausting task. So, turning towards drawing tools seems just right. 

Although there are multiple options out there, the built-in template library and a wide range of symbols make EdrawMax an excellent option. Here is how you can create UML diagrams in just five steps on this design tool.

Read the UML Diagram

There is so much more that goes into UML diagrams apart from the visual appeal. Designers and programmers use UML diagrams to interpret their meaning and implement codes. Here is how to read a UML diagram, so you can make meaning out of it. 

Class Structure

A concept defined within a cell is known as class. A class consists of three primary things, name, attribute, and operations. Here is what each means. 




Class Name

First section of the cell

It is the name of the cell 

Class Attribute

Middle section of the cell.

It is the quality of a class. There can be more than one attribute, and each one is followed by a colon :

Class Operations

Last part of the cell.

The operation that is applied to the class attributes. It determines the behavior of the class, and each one is followed by a bracket ()

Class Visibility

Class symbols are used to determine the accessibility of the class attributes and operations.  Here is a little context of what these three symbols mean. 


Denotes Visibility


To the Public





Understanding the Relationship

Developers build relationships between the actors to interpret the diagram and implement coding. These connections are denoted by different types of arrows. Here is a breakdown of what each relationship between actors means in a UML diagram. 



Denoted By


An action resulted by the behavior of an object of one class

Solid black line


Child and parent relationship of two classes. For instance, Class 2 and Class 3 are subdivisions of Class 1. 

Solid black lines with closed arrows at the end, both meeting a parent class


The relationship between two classes (interface and implementation). For instance, Class 1 has the operation details, and Class 2 is responsible for carrying it out

Two dashed black lines meet a parent class with an open arrow at the end


One class depends on another. For instance, Class 2 is dependent on the Class 3

Dashed line with an open arrow at the end


Relationship between objects of classes. For instance, one class is part of another class. In this case, classes can exist independently of each other. 

Solid line with an unfilled diamond at the end


Type of aggregation. It determines the relationship between objects of classes that cannot exist independently. 

Solid line with a filled diamond at the end
