Boosting Database Performance in Java: A Guide to JPA Best Practices

Java Persistence API (JPA) is a Java specification that defines a standard way to manage relational databases. It provides a high-level, object-oriented view of data persistence, which simplifies the development of Java applications that need to interact with a database.

ORM is a technique that allows developers to map Java objects to relational database tables. This means that developers can interact with a database using Java objects, without having to write any SQL code

JPA provides a number of features that make it easier to manage data persistence, including:

• Entity mapping: JPA allows developers to map Java objects to relational database tables using annotations. This simplifies the process of creating and maintaining mappings between the two types of systems.
• Object-oriented queries: JPA provides a Java Persistence Query Language (JPQL), which is an object-oriented query language that can be used to query data from a database.
• Transaction management: JPA provides a transaction management API that allows developers to manage transactions in a database.
