Spring JDBC CRUD operations

Spring Boot JDBC CRUD operations refer to the basic Create, Read, Update, and Delete operations performed on a database using the Spring Boot framework in conjunction with JDBC (Java Database Connectivity).

Here's a brief overview of each operation:

1. **Create (C)**: This operation involves inserting new records (rows) into a database table. In Spring Boot, you would typically use JDBC to execute an SQL INSERT statement to add data to the database.

2. **Read (R)**: This operation involves retrieving data from a database table. You can use JDBC to execute SELECT queries to fetch data from the database. Spring Boot provides mechanisms to map the retrieved data into Java objects for easy handling.

3. **Update (U)**: Updating data in the database is done using SQL UPDATE statements. In a Spring Boot application, you can use JDBC to execute these statements, typically after fetching and modifying the data.

4. **Delete (D)**: Deleting records from a database is achieved using SQL DELETE statements. Spring Boot, in conjunction with JDBC, allows you to execute these statements to remove data from the database.

To perform these operations in a Spring Boot application, you'll typically follow these steps:

1. Set up your data source configuration in the application.properties or application.yml file.

2. Create Data Access Objects (DAOs) or repositories that handle database interactions.

3. Define methods in these DAOs or repositories for each CRUD operation.

4. Implement the business logic in your service layer to utilize these methods.

5. Expose these operations as RESTful APIs if your application is a web service.

6. Use Spring Boot's dependency injection to manage the components involved in these operations.

By following these steps, you can create a Spring Boot application that performs CRUD operations on a database using JDBC for data access.
