Wrap-up
1. Wrap-up
You made it - congratulations! We've mastered the essential skills to interact with PostgreSQL databases using Java!2. Connecting Java to PostgreSQL
We started by setting up JDBC, executing queries, and managing connections with try-with-resources and connection pooling. These are the foundations of production-grade database access.3. Advanced Query Techniques
Next, we explored prepared statements to protect against SQL injection, filtering and sorting data, and working with joins and subqueries to pull insights from multiple tables.4. Advanced Data Retrieval and Management
Finally, we learned aggregations and grouping, transactions and batch processing for efficient updates, and how to handle large objects like images and text files using BLOBs and CLOBs.5. Congrats!
We've covered everything you need to build Java applications that are secure, efficient, and ready to handle real-world data challenges. Keep practicing and exploring!Create Your Free Account
