It dives into the Java Persistence API (JPA), use of the Entity Manager, Persistence Units, and mapping entities. Spring Data JPA This module introduces participants to Spring Data and Spring Data JPA. It covers configuration using property files, mapping tables and columns, and using primary keys. Key annotations like @Id and @GeneratedValue are introduced along with defining entity relationships such as One-to-One, One-to-Many, Many-to-One, and Many-to-Many. CRUD Operations This module focuses on implementing CRUD operations using JpaRepository and CrudRepository. Topics include Cascade Types, fetch strategies (EAGER vs LAZY), transaction behavior with @Transactional, and using the PagingAndSortingRepository. Querying Data Participants learn how to query data using method naming conventions like findBy and countBy. Both JPQL and native queries are covered. The module also includes the use of @Query and @Modifying annotations and building custom queries.
