Re: How to add relationship lines?
Hello Steve! Apologies for not sharing what I found, I thought everyone on the list knows :) Basically, after dissecting the original .DIA file Hans linked me to, I figured out that the relationships like 1:1, 1:N etc, were defined as properties of the RELATIONSHIP objects! In my opinion, this is far from trivial, especially that it is not explained in the documentation. What I meant about cardinality, I have drawn in red color in the following picture, so you can see it without misunderstanding what I mean. https://www.dropbox.com/s/9asujpcd6o50nve/2013-05-06%2023.43.38.png Please note how this relationship relates to 3 entities - currently in Dia, I have not found a way to set more than 2. Finally a small (really small!) thing: When I double click an object to open its properties (usually only to write its name for start), it would make sense that hitting 'Enter' key, would press ok and close the properties window, without switching hand to mouse to do it - it will streamline the initial design phase :) I hope I've been clear, and provided some constructive ideas/questions :) Genadi.

Re: How to add relationship lines?
Genadi, The advantage of the properties box as it is now it is optional to shut down the properties box at all. If you call it up, you can set the properties, pick apply, dbl lmb a new entity and the properties are then applicable for the new entity. So you can save some mouse picks when you have a number of entities and properties to change. You do not have to hit close until you are done. You can leave the properties box open and it does not affect Diagramming. I hear that being able to select multiple entities and change their properties altogether is coming (good when you want all the properties to be alike among the group). Do not trust rumors however.

I'd never used Dia's ER tools, so thanks for filling me in. After viewing Hans's diagram, I understand what you mean.

Now I understand. I'm wondering whether the ternary relationship described on that page of your book (and thanks for that -- it explained everything, including things I never knew before), really does justice to the true relationship between departments, locations and employees. I see it's a shorthand, but any two can relate totally without the third. When I've coded database apps from database tables, my recollection is I had a single relationship for exactly two tables, and then more relationships for other tables. See this diagram: http://www.a3b3.com/stuff/tri_relationship.dia If I had to write code based on the diagram, I'd find the explicit relationships more explicit. But then again, I've never been trained in what you're doing. Until now, that is, and thank you for that. Thank you for teaching me this brand new capability of Dia. I've used Dia over ten years, and never knew this existed. Anyway, please let me know what you think about the explicit tri-relationship.

How to add relationship lines?
Hello! I've been trying Dia on Ubuntu 13.04 and it works great! I am doing ER Diagrams for various uni assignments in few courses. However, I cant figure out, nor find anything in the documentation about how to create relationships between objects such as 1:N, 1:* etc?
