πβ¨ JDBC Basics β A Hands-On Guide to Core JDBC Concepts!
Welcome to the JDBC Basics Project β your all-in-one Java-based playground to learn and implement the fundamentals of JDBC (Java Database Connectivity) like a pro! π»π
This project is perfect for beginners, students, and professionals looking to master JDBC through clean, modular, and industry-standard code.
π Whatβs Inside?
This repository includes all the essential JDBC operations that every backend developer must know π:
π CRUD Operations (Create, Read, Update, Delete)
- Perform basic database operations on sample data π
- Learn both
Statement
and PreparedStatement
implementations
π οΈ Industry-Standard Code Structure
- Clean code design π§Ό
- Proper DAO (Data Access Object) pattern π
- Separation of concerns for better maintainability βοΈ
β Inserting Multiple Records
- Learn how to insert data in bulk efficiently using JDBC π‘
π¬ Statement vs PreparedStatement
- Understand the difference between
Statement
(static SQL) and PreparedStatement
(dynamic SQL with placeholders) π―
- Prevent SQL injection attacks using best practices π
π¦ Batch Processing
- Execute multiple SQL queries in batches to optimize performance β‘
- Ideal for processing large data sets with minimum latency π
βοΈ Stored Procedure Execution
- Call stored procedures directly from Java to perform server-side logic πΎ
- Learn parameter handling for both IN and OUT types π₯π€
π§ Placeholders with Parameters
- Dynamic query construction with parameterized SQL for safer and more flexible execution ποΈ
πΌοΈ BLOB & CLOB Handling
- Work with Binary Large Objects (BLOB) β e.g., images, files π·
- Handle Character Large Objects (CLOB) β e.g., long text documents π
- Store and retrieve multimedia & documents with ease π
π§° Technologies Used
- π» Java (JDK 8+)
- π MySQL / Any RDBMS of choice
- π JDBC API
- π¦ Maven (Optional for build & dependencies)
π― Ideal For
β
Beginners learning JDBC for the first time
β
Students preparing for backend/database interviews
β
Developers needing a quick JDBC reference or boilerplate
β
Anyone who wants hands-on experience with real database interaction
