Thanks for all that. I made a lot of notes and screen prints and now I'm going to create my own database. I expect to re-watch some sections a few times but the series has given me a good insight into SQL. Thanks!
Amazing work guys! The way you made the whole loop, starting with the table schema in the low level and finishing the same schema in the hight level. Splendid! Thank you! I enjoyed the journey!
I am currently taking an intro to data analytics class for my masters and your tutorials have helped me so much! You are an amazing teacher for newbies like me.
Thank you very much for this videos! I have taken the codeacademy and the Alison courses before yours. I can say your videos were a way better, more simple and direct than theirs.
Hey Mike your tutorials have been very helpful to me especially this one. If you have time can you make a video about converting more complex er diagrams to schema. Like with n-nary relationships and multivalue attributes and such that would be so great because your reasoning is very good and you explain very well.
Hi Mike, really you are an excellent teacher, and perfect coder, your way is direct and extremely simple. if you please can you make a new series focused on practical and real projects. Many thanks . Ahmed
Hi Mike, Thanks for the great video which clearly explains the relationships and the keys. I would like to know more about the foreign keys in case of ternary relationships ? Do you have any write-up or video on this ?
Hi Mike, I watched your 4 hour long vides over the weekend - they are so helpful and easily to follow. Thank you very much. As an frequent Excel user, do you have a video on, or know where I can find good information on, the Excel-like calculations? For example, what should if I want to add a column to an existing table, and populate the column use the product of Existing_Column_1 and Existing_Column_2. Thank you in advance.
i have finished my homework because of this video after trying to find many videos Thank you so much. Better than my professor at uni who just read slides
each video in this serie but esspecially the last three videos are the best i ve ever seen regarding ER Modeling in TH-cam. can you recommend a intermediary - advanced book or resource for ER Modeling & DB Design? Thx indeed..
You're a great teacher, I really want to spend more of my time by watch and code along with your videos. Anyway, if you open a request, create Tableau tutorial would be amazing, I think. Okay that's all, keep it up the great work guys!
As a beginner, I can imagine that I can even set everything on one table... if you don't worry about how messy it is, the reason it separtes to different small talbles, coz it would be easier to read
What about in the case that I have multiple partial keys in my weak entity? For example, my ER Diagram has the weak entity "Section", it has 3 partial keys, "Semester" "Year" and "Section #". The owner of this weak entity has the primary key as "Course #" The relationship between them is "HAS" and it's a many-to-many relationship. What would I put as my keys for this "HAS" table? Would it be Course# and all the other partial keys from "Section"? Or just Course# and Section#? Sorry if this is confusing but I'm super lost here. Thank you in advance!
Hey Mike, awesome work! I really do appreciate your effort. How did you create those diagrams and tables? I mean how did you visualized it, is there any function at PopSQL to transform data into tables and diagrams? Thank you in advance for your help!
This video is 10x better than my university professors lecture :D
change your university and see dumbest one
Biggest facts i've ever seen written
Wow an entire week of lecture summarized in just 5 minutes of a video on 2.5x speed. Thanks a lot, great work!
Right? This video made so much more sense to me than any college professor I've come across.
how on earth did you get 2.5x on youtube?

My Workflow is as follows.
See what professor is supposed to teach
TH-cam it
Learn in 1/10th the time.
(0:39) STEP 1 : Mapping of Regular Entity Types
(1:41) STEP 2 : Mapping of Weak Entity Types
(2:49) STEP 3 : Mapping of Binary 1:1 Relationship Types
(4:22) STEP 4 : Mapping of Binary 1:N Relationship Types
(6:25) STEP 5 : Mapping of Binary M:N Relationship Types
(8:43) Define the relationships
(9:36) Create an actual database
Thanks for all that. I made a lot of notes and screen prints and now I'm going to create my own database. I expect to re-watch some sections a few times but the series has given me a good insight into SQL. Thanks!
Best explanation of these concepts I've ever heard and I've been trying to get it for a while. Thanks. Teaching is clearly your calling.
Thank you. After reading about entities and relations for two hours, this summed it all up perfectly!
Thank you, I attended all the course it was really helpful. World needs people like you thanks for your time and your great way of teaching.
Amazing work guys!
The way you made the whole loop, starting with the table schema in the low level and finishing the same schema in the hight level. Splendid!

Thanks for making SQL learning easy for us Mike
Thank you very much for this videos! I have taken the codeacademy and the Alison courses before yours. I can say your videos were a way better, more simple and direct than theirs.
U saved us bro. we had system diagram projects and this 100% made everything clearer
Thank you so much for making all videos!
You are legend.
This course got me introduced to SQL and I am starting a Project right away!
I am Taiwanese, your course is very good, thanks for teaching!
You are so clear in your explanation!
Thanks for summarising 2 lectures of 1 hour each in 10 mins, and way easier to grasp!!!

Amazing tutorial
You're so cool Mike!
That was great!
Nicely understand !!
This was great lesson. Thanks a lot.

Really help me to complete my assignment. Great explanation
Same to you got it.
great explanation thanks
Ziraff academy
thanks for the free mysql course mate
Awesome.
Thanks a lot
It really helped me
How much i hate this subject :D Anyways thanks for the video. It was much easier than reading 120 slides
Great video.
Excellent. Clearly understand what are you say. Please add ISA hyrachy mapping
Great help ✌️
it's really a great explaination
superb!! thanks
Yaw Mike am fan of you, watching from Maryland
really helpful thank you
Thanks for the video, I just use it to take my examination it is really really helpful.
Hey mike you are awesome,just you didn't mention multivalued attribute.
LIFE SAVER TY TY TY
Hi Mike can you explain derived attribute in this example
Thanks a lot!
This is gold
can you explain about the BCNF(Boyce-codd Nornal Form)?
What do you use to build database and table
Why do you have super_id in the employee table?
does anyone know how he drew the relational model? I mean the software used ???
As a beginner, I can imagine that I can even set everything on one table... if you don't worry about how messy it is, the reason it separtes to different small talbles, coz it would be easier to read
6:30 there are actually two m:n relations
prathi sahrudh the other one is a weak entity we mapped it already
In 3 videos i learned more than an entire semester….
no cap
you are amazing
Can you explain how to test database for my assignment I need that
thank you!
can you tell me what happen to age from Employee table and # of employees from Branch table. Those are derived attribute right?
Hi, Do you have how this created in MS SQL?
What about in the case that I have multiple partial keys in my weak entity?
For example, my ER Diagram has the weak entity "Section", it has 3 partial keys, "Semester" "Year" and "Section #".
The owner of this weak entity has the primary key as "Course #"
The relationship between them is "HAS" and it's a many-to-many relationship.
What would I put as my keys for this "HAS" table?
Would it be Course# and all the other partial keys from "Section"? Or just Course# and Section#?
Sorry if this is confusing but I'm super lost here. Thank you in advance!
What is if we have a terner relationship & not Binary? How to represent that?
Can you talk about generalization/specialization, aggregation and ternary relationship in your next video?
Hi, if you have a 1:N relation should an attribute on that relation eg. price be included in the relation schema? And where if it should?
Hey mate plz help me create a conceptual schema from a given tables for the database management 😢
Nomalisation part!?
Subd straight away
Nice Sir Thanks Sir.
Hey Mike, awesome work! I really do appreciate your effort. How did you create those diagrams and tables? I mean how did you visualized it, is there any function at PopSQL to transform data into tables and diagrams? Thank you in advance for your help!
