ORM-Object/Relation Mapping
For more information, see baike.baidu.com/view/197951.htm.

Generally speaking, this type of framework is used to map class objects and relationships, and establish an intermediate layer between application programs and database IO, in a program, you only need to directly operate on objects (adding, deleting, modifying, and querying objects in the database), instead of worrying about columns and relationships in tables in the database.

For example:
I used to eat at home by myself. I had to buy rice for food, and then I did it myself. I had to clean up after I had done it. I felt very troublesome, but I had to do it too. I couldn't help it. I was a single man --
This is equivalent to the traditional operational relationship (not using ORM );
One day, I found it very convenient to eat at a restaurant. I don't have to worry about buying food or anything, and I have to pick up a lot of food after I finish eating it, you just need to pay for your food and leave the house.-anyone else can cook and cook food. you don't have to worry about how people do it --
This restaurant is equivalent to an ORM ing framework. it handles tedious and boring things for you and only takes the most important part-eat-for you to do it.
Ordering is equivalent to configuring ORM ing. if you tell the restaurant what you want to eat, the restaurant prepares food according to your needs. once you have prepared the food, it will be sent to you!
