The JdbcTemplate abstraction provides low-level access to database queries, allowing developers to write custom queries and perform CRUD operations in a flexible and efficient manner. By leveraging the JdbcTemplate abstraction, developers can create applications with a high degree of customization and control over database interactions. The tutorial demonstrates how to use JdbcTemplate to create a Spring Boot application that performs CRUD operations on a MySQL database, including adding, reading, updating, and deleting employees. The example code provides a comprehensive overview of the JdbcTemplate abstraction and its usage in a real-world scenario.
