Comments on annotations The Java Persistence API (JPA) defines several ways to access data: Through an entity manager, through JPA-QL, or through a native query. In JPA, annotations are used as a mechanism for mapping Java objects to the underlying database. You can also provide XML metadata as an overlay or an alternative mechanism for mapping annotations.

Summary Developers try to avoid tedious programming in a variety of ways. Some programming rules, such as inheritance, polymorphism, or design models, can help developers avoid generating unwanted code. However, because of the uncertainties in software development, these rules do not eliminate the need for code maintenance and rewriting. Maintenance is unavoidable in many cases, and only software that cannot be operated is never required to be maintained. However, this article describes the fun
