source : docs.oracle.com

Introduction:

Java, a programming language renowned for its versatility, provides developers with multiple tools for connecting applications to databases. Among the prominent technologies, JDBC (Java Database Connectivity) and JPA (Java Persistence API) stand out. In this comprehensive article, we will explore these technologies in-depth, elucidating each term and offering a thorough understanding of their functionalities. The discussion will remain straight to the point, accompanied by a plethora of practical Java code examples to solidify the concepts.

Java Database Connectivity (JDBC):

JDBC, an acronym for Java Database Connectivity, stands as the foundational technology for connecting Java applications to relational databases. As a low-level API, JDBC offers a standardized approach to establish connections, execute SQL queries, and process the ensuing results.

Connection Establishment:
To delve into the depths of JDBC, let’s start with connection establishment. This involves loading the JDBC driver, creating a connection URL, and using the DriverManager to establish a connection. The following code provides a simplified illustration:

import java.sql.Connection;
import java.sql.DriverManager;
