What is a foreign key
A foreign key (FK) is one or more columns that are used to establish and strengthen a link between two table data. You can create a link between two tables by adding one or more columns that hold the primary key values in the table to another table. This column becomes the foreign key of the second table.
Why foreign keys are used.
Ensure referential integrity of data
It's not going to happen.
No, not much. If a robust system, the data in the database must have goo

In this case, the terrain is actually a series of grids with different heights, so that the index values of each element in the array can be used to locate unused grids (x, y ), the stored value is the grid height (z ). It is precisely because of this simple ing relationship that the

Dynamic AllocationIn your problem, you create objects in two ways. The main difference between the two approaches is the storage time of the object. When executing object MyObject, this code is created as an automatic variable, which means that the object is automatically destroyed when it is scoped. When you use new object () This way, the memory that the object has is allocated dynamically, which means that the object is not destroyed until you call
