I am trying to represent a one to many relationship where 1 artist will have many albums and each album will have 1 artis.
This box will give you the options to "Add Multiplicities" or "Reverse Line Direction." You can use the multiplicities to indicate how many points you are making. I am very new to UML and am using Lucidchart to model some classes in java. You can also add multiplicities to an ERD diagram the same way you add them with UML shapes (see below for more details).Īfter you connect two shapes together with a line, you can click on the line and a dialogue box will appear. Just click on the line and then you'll see the top options bar will change to include two drop down menus, each referring to a different endpoint of the line. Once you connect two shapes, you can click on the line in the middle and change the endpoints to be an arrow, crows foot, or any of our other line endings. I've described the appropriate steps below, but I've also recorded this screencast to show you the steps: I'm not sure if you're asking about showing a one-to-many relationship in ERD or in UML, so I'll answer both. Thanks for your question! I actually work for Lucidchart, so I'm happy to help.
