an interesting explanation of ERD, step by step in a simple, slow way that makes it easy to understand, thank you Mr. Dr. May Allah increase your knowledge
Thank you for this step-by-step demonstration of constructing an ERD. It is explained in a very simple way for beginners like me to understand and follow. Appreciate your tutorial.👍
This video isn't really about an ER diagram. It is talking about a "relational model". An entity/relationship should not be talking about primary key or a combination key and such relational database terms. E.g. "An employee works for a department" - there are two entities "Employee" and "Department" and the relationship is "works". So you should pick the 'entity' icon on the left (rectangle), and the relationship icon on the left (diamond shaped). Then you draw the cardinalities (one-one, one-many.. etc). Between the rectangles (entities) and the relatioship (diamond), you draw the cardinality lines (one, many, etc).
OK, and how do I create a composite PK which consists of 3 fields? Anything I try, it puts it in a different row that is divided by a horizontal line. I'm unable to put 3 PK's between two horizontal lines. Like the two PK's in the EmployeeSkill here, only I want a 3rd one in there too. How to do that??
I got an exam and it says: In this worksheet you will practise normalising data to produce an ERD from a paper-based record. So I have to do the same as you done or I need to uce access
This is not an ER diagram. It is a relational schema. ER diagrams are part of the conceptual database design and aren't related to a specific database type.
Thanks for a nice explanation of draw.io Please do not add 'music' in future videos as it is distracting a lot for hearing impaired people. If possible, remove in this one.

4:58 thank you! I was looking for this :)
same lol is there a way we can copy and paste attribute names into the rows?
Thank you for this, my teacher sort of threw us this program without explaining how it works at all. Very helpful!
Thank you. Very informative. I was struggling to use it. But now i'm confident enough to draw erd.
AMAZING tutorial, very concise and very well explained! I will have fun now creating tables for my PostgreSQL database!
Dr Soper, your presentation are ever on point!
Thank you so much.

thanks very much . very useful quick summary
Very nice and beginner friendly tutorial. Well done.
can you add more columns to the relationship table? or only rows?
OK, and how do I create a composite PK which consists of 3 fields? Anything I try, it puts it in a different row that is divided by a horizontal line. I'm unable to put 3 PK's between two horizontal lines. Like the two PK's in the EmployeeSkill here, only I want a 3rd one in there too. How to do that??
This was very well presented! And helpful!

Thank you Dr. Soper! I'm including your video in the materials for my SQL course.
Thank you so much. It helped me lot.
Thanku very much it was really helpful 👍😉🥀🥀❤️❤️
Thank you it has been really helpful for my assignment. For the lines though, why not just use "duplicate" instead of copy and paste?
Finally, can I save the design and copy it?
Is it possible to fill in the table names and column names via a csv or excel upload?
Thanks so much. it was a quick and very helpful tutorial.
I got an exam and it says: In this worksheet you will practise normalising data to produce an ERD from a paper-based record. So I have to do the same as you done or I need to uce access
Thankyou. This is so Clear tutorial
thank you this is very clear and got me up and working quickly

How to generate the SQL for the models?
Very useful video, thank you for your sharing!

HOW TO JOIN TWO LINES FROM DIFFERENT TABLES THAT POINT TO THE SAME PRIMARY KEY ON A TABLE WITH SAME CARDINALITY?
Thank you very much for your video!
Thank you! - this was simply perfect. ¿What do you use to dim part of the screen while explaining, so we focus our attention on the non dimmed part?
thank you , this video really helped me
One Question. In the Logical Model E-R, In the table i can put of type data???
I think you add the data type in your data dictionary
This is not an ER diagram. It is a relational schema. ER diagrams are part of the conceptual database design and aren't related to a specific database type.
