principle of caching is that when the CPU needs to read a piece of data, it first looks for it from the cache. if it finds it, it immediately reads it and sends it to the CPU for processing. If it does not, it reads data from the memory at a relatively slow speed and sends it to the CPU for processing. At the same time, it transfers the data block of the data to the cache, this allows you to read the entire block of data from the cache without calling the memory.
This reading mechanism makes t

What is level-2 cache?
The session of Nhibernate provides a level-1 cache. Each session loads the same ID twice and does not send two SQL statements to the database. However, once the session is closed, the first-level cache becomes invalid.
Compared with Session, sessionfactory also provides a caching mechanism.
1. Function IntroductionThis program simulates multi-level menu operation, the implementation of a menu item corresponding to the digital index into the sub-menu, press the B key back to the previous menu, press the Q key to exit the menu. A three-level menu test is performed with a simplified discipline catalog, which can be used in virtually any multilevel menu operation.
First, understand several concepts:
1. Reference a common variable to obtain a level-1 pointer. For example, if int A = 0; int * P = A, A is the first-level pointer. Because the value of A is the address of a and the value of P is also the address of a, then A and P are the first-level pointer variables (simple as pointers ), unreference A, int B = * A; t
. Each session has a data cache, which exists with the creation of the session and perish with the destruction of the session, it is also called session level cache.
