== Preface
Working with both Object-Oriented software and Relational Databases can be cumbersome and time-consuming.
Development costs are significantly higher due to a paradigm mismatch between how data is represented in objects
Development costs are significantly higher due to a number of "paradigm mismatches" between how data is represented in objects
versus relational databases. Hibernate is an Object/Relational Mapping (ORM) solution for Java environments. The
term Object/Relational Mapping refers to the technique of mapping data between an object model representation to
a relational data model representation. See http://en.wikipedia.org/wiki/Object-relational_mapping for a good

Although having a strong background in SQL is not required to use Hibernate, having a basic understanding of the
concepts can help you understand Hibernate more quickly and fully. An understanding of data modeling principles
is especially important. Both http://www.agiledata.org/essays/dataModeling101.html and

Hibernate takes care of the mapping from Java classes to database tables, and from Java data types to SQL data
types. In addition, it provides data query and retrieval facilities. It can significantly reduce development
