Open Source Java Object-Relational Mapping (ORM) Software

Now stored at https://github.com/gregorydgraham/DBvolution Available from Maven Central: nz.co.gregs.dbvolution Makes relational data easy and fast to use with semantic annotations and encapsulated datatypes. Simple declaration of a DB table: @DBTableName("mytable") public class MyTable extends DBRow { @DBColumn("numeric_code") @DBForeignKey(Code.class) private DBNumber numericCode = new DBNumber(); @DBColumn("uid_mytable") @DBPrimaryKey @DBAutoIncrement private DBNumber uidMyTable = new DBNumber(); } Easy Gets: List<MyTable> myRows = myDB.get(new MyTable()); MyTable row = myDB.getDBTable(new MyTable()).getByPrimaryKey(61176904); Natural and Outer Joins and Criteria: CarCo carCo = new CarCo(); carCo.name.isLiterally("GM"); List<DBQueryRow> results = myDB.get(carCo, new Marque()); dbQuery.addOptional(new CarModel()); Easy debugging: query.getSQLForQuery(); Simple processing: db.print(query.getAllRows()); List<Marque> marques = query.getAll

An XML DOM for Java, and for humans. Candor is a fork of XOM (http://xom.nu/), modifying it to support modern Java features.

Flexoodb stands for Flexible Object Oriented Database API. Using your choice of RDBMS, Flexoodb represents objects as XML, allows proprietary Serializable objects to be embedded within the XML representation and manipulation using extended classes.

MockSqlBuilder uses mock objects and method interception to build SQL queries in an OOP fashion. Instead of strings (like HQL or plain text), MockSqlBuilder uses the data object's and their methods to record and construct a query.

[NO LONGER UPDATED] The Simple Hibernate Data Handler implements a basic interface for CRUD, suportting HQL, Named Queries and SQL. Stupidly simple for Hibernate ORM 4. Extend a BasicCrud class and enjoy!
