Layers

Java Application ↓ JDBC API (java.sql, javax.sql) ↓ JDBC Driver Manager ↓ JDBC Driver (Database specific) ↓ Database (MySQL, Oracle, PostgreSQL)

JDBC Driver Types

Type	Name	Description
Type 1	JDBC-ODBC Bridge	ODBC driver use karta hai (deprecated)
Type 2	Native API	Native C/C++ library
Type 3	Network Protocol	Middleware server
Type 4	Thin Driver	Pure Java, most common

Type 4 (Pure Java / Thin Driver) most common aur recommended hai.

Key JDBC Interfaces

Interface	Purpose
`Driver`	Driver register karna
`Connection`	DB se connection
`Statement`	Simple SQL execute
`PreparedStatement`	Parameterized SQL
`CallableStatement`	Stored procedures
`ResultSet`	Query results
`DatabaseMetaData`	DB information
`ResultSetMetaData`	ResultSet column info

Connection URL Format

jdbc	mysql://hostname:port/database?parameters
jdbc	mysql://localhost:3306/mydb
jdbc	mysql://localhost:3306/mydb?useSSL=false&serverTimezone=UTC
jdbc	postgresql://localhost:5432/mydb
jdbc	oracle:thin:@localhost:1521:xe
