The relationship between 8 sorts:
1, direct insertion sort
(1) Basic idea: In the set of numbers to be sorted, suppose that the front (n-1) [n>=2] number is already a row
In a good order, now you have to insert the nth number into the preceding ordered number so that the number of n
It's a good order, too. Repeat the loop until all the order is sorted.

is not suitable for addressable memory space. (We'll talk in the back to addressable memory.) This means that DB2 cannot start the database because a database must have at least one buffer pool. If the database does not start, you cannot connect to the database, and you cannot change the size of the buffer pool. For this reason, DB2 pre-allocated 4 such small buffer pools. This way, once the primary buffer
