Second: the Java Language Foundation
The more than 20-year-old Java language, with its cross-platform, object-oriented, distributed computing features, is widely used in Web sites, mobile devices, desktop applications, and has been in the forefront of Tobie programming languages for many years, and has recently topped the throne. It's important to know what's good and what's different in Java first.

2-11 Network Programming
Principles and application Scenarios of network communication protocols, socket programming, how Web servers work
2-11 JDK1.5, JDK1.6, JDK1.7, JDK1.8 What are the new features that each version adds to the previous version, and what improvements are made
Three: Database-related
In front of the data structure, the database is simply like an electronic filing cabinet, is to organize, store and manage data warehouse according to a certain data structure.
3-1 Theoretical basis
Database design principles and paradigms
Transactions (ACID, working principle, isolation level of transactions, locks, propagation mechanism of transactions)
3-2 various database advantages and disadvantages, usage scenario analysis

Triggers, stored procedures, transaction control
3-3 optimization
Index principle and application, large table query optimization, multi-table Connection query optimization, sub-query optimization, etc.
3-4 Library, sub-table, Backup, migration
Import, export, sub-Library, table, cold standby hot standby, master-slave backup, dual standby, vertical expansion, scale-out
3-5 JDBC
Use of different classes such as JDBC Connection, Statement, PreparedStatement, callablestatement, resultset, etc.
Connection pooling (configuration usage, implementation principle)
Orm,dao
