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
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).
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.👍
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.
My crapy teacher tells everyone to label the line, and don't make it looks like a process. What can I say, I just write all 'has' customer has payment detail, the bank has payment detail and team member has the payment detail, fuck

@Dr. Daniel Soper, Can you please make a physical entity diagram? I am kinda confused on how the logical and physical are different
Yes please
👍
super amazing video, cant resist to watch & like.
can you add more columns to the relationship table? or only rows?
Thank you, great tutorial
Hello, very helpful video and loved it, but how do you add more columns to the table to fit more attributes?
thank you this is very clear and got me up and working quickly
Thanks so much. it was a quick and very helpful tutorial.
Thank you for the info. Easy to understand
Arrange > Insert > Advanced > CSV
Then insert your SQL statement (there is an example) and you're halfway there.

Very well defined . Good Job
This is an amazing tutorial. Thanks a lot!
Very useful video, thank you for your sharing!

Thanku very much it was really helpful 👍😉🥀🥀❤️❤️
Thank you very much for your video!
This was perfect, thank you!
Thank you for tutorial, it's really useful
Thank you it has been really helpful for my assignment. For the lines though, why not just use "duplicate" instead of copy and paste?
