== Getting Startedanchor:Getting_Started[]
+
+Using JDO requires several components that work together:
+
+* a database that stores your data persistently
+* an application that operates through the JDO layers on the database
+* a JDO implementation that provides the implementation of the JDO APIs
+* Java classes (object model) that provide the application view of the data
+
+A good place to start is to define your object model. This is the collection
+of Java classes that you use to represent the persistent data in your
+database. Some JDO implementations allow you to create your database schema
+from your object model. Or you might already have a database and database
+schema that you can use to derive the object model.
+
+You will also need to define Java classes that implement the application
+that operates on the object model. The application is responsible for
+using the JDO implementation classes to define the application view of
+PersistenceManagerFactory and PersistenceManager.
+
+Next, choose a JDO implementation. You can get information
+on JDO implementations here. Some factors to consider when choosing
+a JDO implementation is what databases they support, what Java version
+they support, and whether they provide tools to create database schema from
+an object model or create an object model from the database schema.
+
+Some JDO implementations also package the JDO interfaces as a separate
+jar file, so there may be no need to download the JDO interfaces from this
+site.
+
+More information on how to proceed can be found on your JDO implementation
site.
