    What Are UML Diagrams?

    UML or Unified Modeling Language is a modeling technique used to document software. UML diagrams visually represent a system along with its main actors, roles, actions, artifacts or classes, in order to better understand, alter, maintain, or document information about the system.

    Things to Remember While Creating UML diagrams

    • When creating UML diagrams it is important to remember to create levels of abstractions that meet the need of your audience. Creating unnecessarily complex diagrams with too much information can confuse stakeholders. When creating UML diagrams with Creately’s UML diagram tool you can create multiple diagrams on different workspaces and link them together for better comprehension.
    • Avoid lines crossing over each other while creating UML diagrams. This allows your diagrams to be more readable and understandable. If two lines must cross, use a “bridge” to show that the lines do not intersect.
    • Try to make sure all lines go horizontally or vertically and create right angles with each other. When drawing connectors, having lines with multiple connectors make diagrams look messy and confusing.
    • When drawing generalization or realization hierarchies on a diagram always make sure the parent elements are higher than the child elements so the arrows always point upwards.
