I've worked on thousands of databases, yet I watched both parts with laser focus. The quality of this content is simply incredible. I wish I had access to that when I started out.
The fact it can convert the diagram to code to create the tables! And to be able to do it in reverse from database to diagram! That is awesome and such a big time saver🙏🏾 thank you 😊
Please make more "lucid explains the internet" videos. Such as the snek and doggo videos. These are still being shared around social media to this day.
a great explanation, as always. one thing is missing for me - the relationship between entities(other than the quantitative you mentioned), and dependant entities and their notation. thanks alot!
THANK YOU SO MUCH! I always used the export button in the right panel (it is much more prominent) and I found it so annoying to have to export all tables one by one.
Best animation on the topic. I will recommend it to my students in Pakistan. Can you tell me the software in which you make these animations . They are so cool.
Hello, and thank you for the great video! Where should I store the meaning of each column? Is it possible to add a 4th column to each table in a second toggable layer? Or should I store the column meanings in a different document in Lucidchart? Or in a different software altogether? Thanks for your insight!
Is there any example of that csv file structure? I dont want to install DB in order to be able to import structure to Lucid. I have prepared the structures in excel. Why is it not possible just simly CTRL+C in my excel and CTRL+V in the entity from ERD in lucid... Can I do that? If not why? Is there some detailed guíde how to import structures to ERD in Lucid, because I can not find any...
I imported an existing SQL Server tables into the ER diagram using TSV export. CSV export is not doing the relationships, so did TSV. Great, it works! a) I placed each entity by clicking. Is there a way to add multiple tables at a single shot? (like ctrl select) b) I have over 80 tables and once placed very hard to find an entity. Is there a way to search the entity on the canvas/diagram? I see shapes pane and by clicking the name, it places one more entity in the canvas, which is not what I am looking for... c) Any techniques for senior data modelers? TIA
you guys should go back to your advertising from 4 years ago. it was kind of sad to discover this gem of a channel with the old ads, and then look and see that it's just a generic corporate channel now :( where snek?
question, for the composite key section, why don't we just add "customer_ID" as a foreign key? it can make it easier to identify the order like in the example of having 2 different items being shipped as two different packages? i am just asking to make sure if my idea is valid. trying to learn and get better at databases here.
So, could only be exported SQL database, how about no SQL database? though it's not a relationship database, however, actually ERD is convenient for get idea what the database structure.
When you sign up for door dash you will be a customer for them but you haven't ordered anything from doordash so you have zero orders whereas your friend may have ordered 5 orders so 0 to many is possible it depends on business requirement
I am student of BSCS so, I have to make a project assignment "Design Document" on "Online mobile showroom app" Can any body help me to make ERD?.................I tried myself but I am confused to draw relationship between entities..

I'm starting out now, technically I'm making my second database, but my first only needed one table, my next one, it won't be so simple. Love youtube!

The CSV to ER diagram functionality in Lucid Chart is huge! Such a simple yet useful idea.

besides the top quatity app and amazing explanation about ERD''s. This guy is a masterclass on how to explain in a way that captivates the audiance
insanely good video, even helped me for my data mining course just to revisit the basics
Make a full course It will be easy to follow in a structured way
I like this guy. He explains everything really well and he is a big dude named Bear. As a fellow big dude i appreciate his name lol.
Bear by name, bear by nature!
what a flippin legend this guy is!!
a great explanation, as always. one thing is missing for me - the relationship between entities(other than the quantitative you mentioned), and dependant entities and their notation. thanks alot!
We need more charts!!! We miss the charts :(
If you do any requests/suggestions: may I suggest more sneke videos?
Great explanation, thank you!
Please make the internet names ads again
THANK YOU SO MUCH!

You are fantastic sir. better than my PSU professor. Thank you so much! Is It possible to make a video about Weak/strong relationships too?

wish wgu used this software for our SQL course
I feel like I should point out that at 4:18, Customer_ID is not 'randomly assigned', it's sequentially assigned. ;-) /pedantMode

What happens if you only know customer name.. you need a composite key to bind the two entities.
hello , can i know where did u get the excel sheet or how do i get it
u can google free excel or csv example data
@@KarMa-ws3ll that specific one is in my lectures that is why i need it the source
We still need a bridge table for order and product, right?
The order table should be the bridging table for customer table and product table.
So, could only be exported SQL database, how about no SQL database? though it's not a relationship database, however, actually ERD is convenient for get idea what the database structure.
So a ssn can be considered a primary key...
Isn't the Shipment table a bridge table too?
Hmm.. maybe the composite table for linking all the info for customers product and supplier by having the keys to all the other tables?
great explanation, I feel composite primary key concept is total waste, instead we can create a primary key and keep it very simple.
Anyone reading this please answer, i dont have database in csv? how should i import database
i miss the sneks
your customer to order relationship is wrong , it should be one to many
Why is that?
When you sign up for door dash you will be a customer for them but you haven't ordered anything from doordash so you have zero orders whereas your friend may have ordered 5 orders so 0 to many is possible it depends on business requirement
But an order isn't generated unless there is at least one order...

Which tool is he using
Lucid
I miss your funny videos.
how do if it is an embedded documents.. like comment collection in post
🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏
Мне кажется, это не для новичков: вроде прикольно, но что делать если есть только 100$? Как их приумножить?
I did'nt get the bridge table
Order table bridges customer table and product table. You have to separate the many to many relationship or you can't link the two..
4:00 insta username can be changed?
Please fix this video to include the correct relationships. order to product is a many to one relationship.
Also the customer id is auto-incrementing NOT random
Wrong.. an order can have one or many products on it and the product can be on one or many orders!!!
So you started turning off comments? What is up with this train wreck of public engagement?
