This course is designed to help you gain a complete understanding of Java Database Connectivity (JDBC), the standard Java API used to interact with relational databases. It is ideal for Java developers who want to build database‑driven applications and understand how Java communicates with databases in real‑world scenarios.

The course begins with an introduction to JDBC, explaining its purpose, architecture, and role in Java applications. You will learn how to establish database connections using JDBC, including required drivers and connection objects.

You will then move on to executing DML commands such as insert, update, and delete operations, followed by executing SQL queries to retrieve data from databases. The course covers Prepared Statements, helping you write efficient, secure, and reusable SQL statements.

Advanced topics include Stored Procedures and Callable Statements, which allow Java applications to interact with database‑side logic. You will also learn batch execution, improving performance for bulk operations, and understand how to work with auto‑increment columns.

The course further explains how to handle binary data using BLOB columns, which is essential for working with images and files in databases. You will also gain a strong understanding of transaction management in JDBC, including commit, rollback, and maintaining data consistency.

A bonus lecture guides you on what to learn next after JDBC. Practice tests are included to reinforce concepts and validate your understanding of JDBC.
