Make a tutorial about uses of one to one, one to many, many to many relationships. What I mean is the practical uses of this feature.
AssadUllahCh (3 months ago)
you are welcome.

Understood.MayAllah blesses you with more precious knowledge. Thanks a lot.

If you watch those tutorials carefully, you will understand the concept of how to apply those relationships to your database as per your needs. Take this example: What would be the relationship between a shopping order and a customer? I think our common sense automatically answers this question if we understand relationships already. One customer can create as zero or more orders. (It gives us the clue that a customer has one to many relationship with orders) Take this case: A specific customer orders a Coke and he makes the payment. The same customer places another order for ice cream and makes the payment. How many orders were placed by this customer? Obviously 2. I just explained the relationship between Customers towards orders. Now it's time to check the relationship in reverse. One order can only belong to one customer. This is also pretty normal. (it's one to one relationship from orders to customers) Suppose your brother bought some juices from a mall and then you bought sneakers from the same mall. How would you differentiate your purchase with your brother? Obviously, the bills you and your brother got would be different having a unique order number as well. IF YOU WATCH MY TUTORIALS RELATED TO RELATIONSHIPS VERY CAREFULLY, YOU WOULD NOT GET CONFUSE.

Yes, I already watched. But those tutorials was to make relationships with tables. I am suggesting to make tutorials about the uses of relationships in the work field(Where to use). If my question is annoying then I seek an apology.
