JDBC (Java Database Connectivity) is a critical API for database interaction in Java applications. Here's a breakdown of its core components:
- Driver Manager
Acts as a mediator between the Java application and the JDBC Driver. It loads the appropriate driver based on the database URL.
- JDBC Driver
A vendor-specific implementation that translates JDBC calls into database-specific protocols (e.g., MySQL, PostgreSQL).
- Connection
Establishes a connection to the database using DriverManager.getConnection(). It manages transactions and session context.
- Statement
Used to execute SQL queries. Includes Statement, PreparedStatement, and CallableStatement for different use cases.
- ResultSet
Stores the data retrieved from the database. It provides methods to navigate and retrieve results programmatically.
