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 JPA Criteria API provides type-safe interfaces for defining query result expressions and ordering, mirroring the SELECT and ORDER BY clauses in JPQL or SQL. These interfaces allow you to specify exactly what data is returned and how it is sorted within the result set. SELECT clause elements

Welcome to the ObjectDB for Java/JDO Developer's Guide. Here you can learn how to develop database applications using ObjectDB and JDO (Java Data Objects), the revolutionary database programming technology by Sun Microsystems. The main purpose of this guide is to familiarise you with ObjectDB

You can use ObjectDB with either the Java Persistence API (JPA) or the Java Data Objects (JDO) API. Both share similar architecture, design and abilities. When to prefer JPA JPA is more commonly used. Therefore, it might be the first choice for most new applications. You can use JPA as
