Label:In modern program development, a lot of development is based on database, the connection of Java database is particularly important. JDBC provides a platform-agnostic standard Java API for executing SQL statements that facilitates uniform operation of multiple relational databases, consisting of a set of classes

Java database connection (JDBC) is composed of a group of classes and interfaces written in Java programming language. JDBC provides a standard API for tools/database developers to write database applications using pure Java APIs.

This article mainly describes the actual operation steps of connecting Java to the MYSQL database (taking MySQL as an example). We use related instances to introduce the actual operation process of connecting Java to the MYSQL database, the following describes the main content of the article. Of course, you must first

Overview: Most application performance management (APM) solutions only consider and analyze performance issues at one level of the Java application. This approach is not sufficient to address the performance problems of architecture-complex applications. A good APM tool should enable you to drill down from the Java EE layer into the database layer to ensure that

the occurrence of Phantom read.Both Phantom and non-repeatable reads read another transaction that has already been committed (this is different from the dirty Read), and the difference is that the non-repeatable read query is the same data item, and the Phantom Read is for a whole group of data (such as the number of data).Now look at the four isolation levels that the MySQL database provides to us:①serializable (serialization): Can avoid dirty read
