Hibernate ..1 st level cashing....
In Hibernate, a popular Java ORM (Object-Relational Mapping) framework, caching plays a crucial role in improving performance by reducing the number of database queries and speeding up data retrieval. Hibernate provides several levels of caching, and "first-level caching" refers to the session-level cache.
First-level caching in Hibernate is associated with the Session object. When you load an entity using a Hibernate Session, that entity and its associated data are stored in the first-level cache. If you try to load the same entity again within the same session, Hibernate will return the cached instance instead of querying the database again. This helps to avoid unnecessary database queries and improve performance.
