Wrap-up

Advanced Data Retrieval and Management

Learn how Java applications work with PostgreSQL databases using JDBC. You will begin by setting up database connections and running queries, then proceed to creating secure, parameterized queries with prepared statements to avoid SQL injection. The course covers techniques like filtering, sorting, and pagination, followed by multi-table queries with joins and subqueries. You will also explore aggregations and grouping operations, implement transaction management to ensure data consistency, and utilize batch processing to efficiently handle multiple operations.
