To access relational databases using the Java Persistence API (JPA) you will need an Object Relational Mapping (ORM) tool, such as Hibernate, TopLink, EclipseLink, Open JPA or DataNucleus. The DataNucleus ORM implementation supports also the Java Data Objects (JDO) API. ObjectDB is a full featured

The Criteria API provides a factory for defining queries programmatically using Java objects

A named query is a statically defined query with a predefined, unchangeable query string. Using named queries instead of dynamic queries can improve code organization by separating JPQL query strings from Java code. This practice also enforces the use of query parameters instead of embedding

+ an optional variable ObjectDB supports using the java .lang.Object class in queries as an extension

Jakarta Persistence (JPA) provides a set of annotations to define and map native SQL queries when the standard Java Persistence Query Language (JPQL) is insufficient. While ObjectDB focuses on JPQL and ignores these annotations, they remain essential for applications interacting with relational

The best source for learning ObjectDB is the ObjectDB Manual , which contains all the necessary information for using ObjectDB. The only required background is a good understanding of the Java language. Reading the manual and getting started with ObjectDB could be easier for developers with prior

Working with the Java Persistence API (JPA) consists of using the following interfaces: Overview A connection to a database is represented by an EntityManager instance, which also provides methods for performing database operations. Many applications require multiple database connections
