Most applications require some sort of data persistence. Developers traditionally have built applications with a specific data store and source in mind, using data store-specific APIs. This approach becomes troublesome and resource-intensive when trying to support and certify an application on numerous persistent data stores. Corticon has chosen the Java Data Objects (JDO) standard to standardize the way in which external data is accessed by Studio and Server.
The JDO specification defines a set of Java APIs that exposes a consistent model to programmers interacting with disparate data sources. More information on JDO is available at http://java.sun.com/products/jdo/.
