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.

[@LGmediaGlobal]

Thank you for this. I was bumbling through it until this tutorial. What a difference!

[@Mark4Jesus]

This was very well presented! And helpful!

[@user-dc7zb8pw7o]

Thank you so much for this quick introduction! Very useful for me, to do my first drawing!

[@bunderbah]

I couldn't figure out how to add rows but now I know. Thank you for the tutorial.

[@ivobaar1761]

This is an amazing tutorial. Thanks a lot!

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

[@crashtest1012]

This was perfect, thank you!

[@rafsan2773]

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

[@liviasheilla3602]

thank you , this video really helped me

[@marylebens1307]

Thank you Dr. Soper! I'm including your video in the materials for my SQL course.

[@emilianogomez2071]

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

[@andrewwoan]

[@kamspal7643]

Thank you for the info. Easy to understand

[@rahi187]

super amazing video, cant resist to watch & like.

[@efoyawi4834]

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

[@djamalinfo2322]

What a fantastic explanation, thanks a lot👏💯

[@myriadpro1641]

this... is... a... LIFESAVER THANK YOU!

[@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).

[@user-nu9kp4jp5f]

its been 4 years but this video is still helpful!

[@homelander973]

Thank you for tutorial, it's really useful

Thank you, great tutorial

[@zafariqbal92]

Excellent! Thank You!

[@yaohongzhao3605]

Thank you very much for your video!

[@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??

[@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?

[@ismulazam7631]

thankyou sir for your bright explaination about erd

[@user-qe9cr4uk9g]

Yeah, very intuitive to add a row... Thanks!

[@coreysheerer8199]

Is it possible to fill in the table names and column names via a csv or excel upload?

@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

[@oliviayolosangweni2669]

So helpful, thank you so much, I

[@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?

[@HienNguyen-cb8ud]

Many thanks Sir!

TG for KZbin, amazing video

[@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

[@ayyeyo]

Thanks man.

[@miaoruibo3803]

Damn it's really helpful

[@JokerJax]

can we connect data and automatically create erd

[@fikirtezewdie6708]

Very useful

[@DavidLevy-rh2os]

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

[@_ifly]

how to add new line .

[@debapratimchanda8326]

thanx bro thanx bro'

[@phrjcf]

💯💯

[@JoseGejunVanBoy]

What app is this?

[@nelamminz1107]

Which app

[@manishadhikari7050]

Is it entity relations or crows foot

[@bugsqli9301]

👍

[@NostraDavid2]

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

[@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 ;-)

[@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.

[@ayalilichan2654]

nao achei em portugues, vai em ingles mesmo kkkkkk

[@josefinamagallanes8451]

is this free?

[@joannaliezl3844]

the sound is not good I am quite disappointed

[@Hector21211]

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

[@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

[@DaRyteJuan]

UGH! The music!!! 🤮
