Logical operators in JPQL and in JPA criteria queries enable composition of complex JPQL boolean expressions out of simple JPQL boolean expressions. Logical Operators ObjectDB supports 2 sets of logical operators, as shown in the following table: Set 1 - JPQL / SQL Set 2 - Java / JDO AND && OR

Persistence fields can either be accessed by JPA directly (as fields) or indirectly (as properties and get/ set methods). JPA 2 provides an annotation and an enum for setting the access mode: More details are provided in chapter 2 of the ObjectDB manual.

Criteria Queries The CriteriaQuery interface provides methods for setting the ORDER BY clause ... (c. get ("population"))); Unlike other methods for setting criteria query clauses - the orderBy

A JPA Persistence Unit is a logical grouping of user defined persistable classes (entity classes, embeddable classes and mapped superclasses) with related settings . Defining a persistence unit is optional when using ObjectDB, but required by JPA. persistence.xml Persistence units are defined in

on a different physical device by setting the path attribute in the configuration . The recording

The JPA Criteria API interfaces in this group are used for setting the SELECT and ORDER BY clauses and for representing query results as tuples. SELECT Clause Elements The content of the SELECT clause in a criteria query is represented by Selection : Because Selection  is a super interface

JPA defines three types of persistable classes which are set by the following annotations: Chapter 2 of the ObjectDB manual explains these annotations in detail. Entity and mapped super classes can be further configured by annotations that specify cache preferences and lifecycle event listener

The way a field of a persistable class is managed by JPA can be set by the following annotations: Additional annotations (and enum) are designated for enum fields: Other additional annotations (and enum) are designated for date and calendar fields: Chapter 2 of the ObjectDB manual explains how to use all the above annotations.

The interfaces in this group are in use for setting a criteria query FROM clause. Criteria Query Variables The FROM clause  in JPA queries (as in SQL) defines the query variables. Query variables are represented in criteria queries by descendant interfaces of the From interface: Range

The way a field of a persistable class is managed by JDO can be set by the following annotations and enum types:

JDO supports two modes of persistable classes that can be set by the following annotations: Non persistable classes that should be enhanced (because of accessing persistent fields of other classes directly) can be marked with: The identity mode of persistence capable classes can be specified by using:
