The advantages of JPA are given below :
* The burden of interacting with the database reduces significantly by using JPA.
* The user programming becomes easy by concealing the O/R mapping and database access processing.
* The cost of creating the definition file is reduced by using annotations.
* We can merge the applications used with other JPA providers.
* Using different implementations can add the features to the standard Implementation which can later be the part of JPA specification.
