multithreading technology provides implementation possibilities, and thread creation and destruction may be time-consuming, like using an object pool, we must use a thread pool to optimize multi-thread parallel computing. Using the thread pool and Object pool, each time a client request occurs, a thread is borrowed from the thread pool. After processing the request, the thread is returned to the thread poo

Ado|connection| object What is a connection object? A Connection object describes the physical connection to the data source. You can also use OLE DB to connect to a data source using ODBC.

We must consider this from a scalable perspective.Task 4: manage database objects.Managing database objects is the most basic and important task of using databases. These objects include tables, indexes, views, stored procedures, functions, triggers, synonyms, and so on. To manage database objects, DBAs should be able to answer the following questions well.What data should the system c

So, to go deeper, the implementation of AOP is actually a dynamic proxy for Java.The second question is, first of all, about the transactions in the database, and then how spring handles the transactions in the database. In layman's words, a database transaction is a one-time commit when you need to inser
