Preface

JDO provides transparent persistence of your Java object models in transactional datastores. It allows you to define your object model using all the capabilities provided in Java and it handles the mapping of that data to a variety of underlying datastores. You do not need to learn and understand a different data-modeling language like SQL. You will discover that JDO is very easy to use. Many development organizations are discovering the significant development productivity advantages that can be realized by using JDO.
