Creating Entity Relationship Diagrams using Draw.io

Dr. Soper demonstrates how to create entity-relationship diagrams (ERDs) using Draw.io. Topics covered include creating entities and attributes, defining primary and foreign keys, marking attributes as required, creating and modifying relationship lines, changing cardinalities, creating weak entities, and marking relationships as non-identifying.

[@rohitxess1955]

Thank you. Very informative. I was struggling to use it. But now i'm confident enough to draw erd.

[@loebys]

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

[@aaronzeka3196]

Dr Soper, your presentation are ever on point!
Thank you so much.

[@LGmediaGlobal]

This was very well presented! And helpful!

[@zappertxt]

[@danielmaserrat5060]

same lol is there a way we can copy and paste attribute names into the rows?

[@ivobaar1761]

This is an amazing tutorial. Thanks a lot!

[@blossomnature6257]

Thanks a lot for the tutorial. One of the best offline tools for database design well explained

[@garrydenewaldie7257]

[@user-nu9kp4jp5f]

its been 4 years but this video is still helpful!

[@emilianogomez2071]

I'm really thankful with you, I needed add a new attribute!!!

[@ibrahimozmen9668]

Thanks so much. it was a quick and very helpful tutorial.

[@RA-do6et]

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).

[@kamspal7643]

Thank you for the info. Easy to understand

[@liviasheilla3602]

[@ismulazam7631]

thankyou sir for your bright explaination about erd

[@orwakassab8326]

Thanks for this tutorial

[@efoyawi4834]

can you add more columns to the relationship table? or only rows?

[@vsp2022]

Great....Software...and also nice explanation

[@rafsan2773]

Hello, very helpful video and loved it, but how do you add more columns to the table to fit more attributes?

[@kiddosknowledgewizbyakshit9954]

very useful video....Thanks a lot

[@HienNguyen-cb8ud]

Many thanks Sir!

[@cleidsonsantana1401]

perfect, thanks !

[@oliviayolosangweni2669]

So helpful, thank you so much, I

[@tamask]

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??

[@md.robelahammed5137]

thanks a lot...it's helpful

[@huytrinh3823]

thank you Sir !

TG for CZcams, amazing video

[@shanabenjamin8945]

Thank you

[@jodyw8713]

Thank you it has been really helpful for my assignment. For the lines though, why not just use "duplicate" instead of copy and paste?

[@bezualemfisseha2119]

Thank you very much you save me

[@minirose4763]

[@miaoruibo3803]

Damn it's really helpful

How to generate the SQL for the models?

[@stevenhe3462]

Good vid!

[@JokerJax]

can we connect data and automatically create erd

[@roxinnjeru5837]

HOW TO JOIN TWO LINES FROM DIFFERENT TABLES THAT POINT TO THE SAME PRIMARY KEY ON A TABLE WITH SAME CARDINALITY?

[@nessacampbell142]

@Dr. Daniel Soper, Can you please make a physical entity diagram? I am kinda confused on how the logical and physical are different

[@ABC-333]

Yes please

[@bugsqli9301]

👍

[@fikirtezewdie6708]

Very useful

[@darkpekka1745]

hey really appreciated your sentiment analyser wanna talk a little more about can i get ur contact ?

[@cerfux]

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?

[@lys6009]

Cool!

[@fannypastor4942]

One Question. In the Logical Model E-R, In the table i can put of type data???

[@havelboumbidi440]

I think you add the data type in your data dictionary

[@makmo3gza]

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

[@debapratimchanda8326]

thanx bro
thanx bro'

[@_ifly]

how to add new line .

[@phrjcf]

💯💯

[@DavidLevy-rh2os]

Hi, can you export the model to a sql script?

[@NostraDavid2]

Arrange > Insert > Advanced > CSV
Then insert your SQL statement (there is an example) and you're halfway there.

[@nelamminz1107]

Which app

[@JoseGejunVanBoy]

What app is this?

[@manishadhikari7050]

Is it entity relations or crows foot

[@bugsqli9301]

👍

[@samsmith8691]

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.

[@bugsqli9301]

Ryt

[@ruggeddog3103]

soo GITMIND.COM OR DRAW.IO ???

[@drawioapp]

easy one ;-)

[@ayalilichan2654]

nao achei em portugues, vai em ingles mesmo kkkkkk

[@josefinamagallanes8451]

is this free?

[@HansvanDam1944]

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.

[@heatherstark5003]

Agree it would be better without music - very nice tutorial but I found the music distracting and annoying, entirely unnecessary.

[@joannaliezl3844]

the sound is not good I am quite disappointed

[@DaRyteJuan]

UGH! The music!!! 🤮

[@user-ti7me6yv7w]

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

[@techaddictdude]

lol

[@Hector21211]

jajaja wesbrok y lebrom juegan tan iguales que los dos engañan con numeros
