Master Microservices with Spring Boot and Spring Cloud - Step 2 – World Before JPA – JDBC, Spring JDBC, and myBatis

The video tutorial introduces pre-JPA approaches like JDBC, Spring JDBC, and MyBatis, explaining how each handles database queries and parameters. JDBC requires manual query handling, while Spring JDBC simplifies this with a JDBC template. MyBatis uses XML and annotations for mapping. The video highlights the challenges of maintaining complex queries, setting the stage for JPA's introduction in the next video.

Describe the process of mapping results from a query to Java objects in JDBC.
