Open Source Java Object-Relational Mapping (ORM) Software

Hibernate is an Object/Relational Mapper tool. It's very popular among Java applications and implements the Java Persistence API. Hibernate ORM enables developers to more easily write applications whose data outlives the application process. As an Object/Relational Mapping (ORM) framework, Hibernate is concerned with data persistence as it applies to relational databases (via JDBC).

DataNucleus provides Java data persistence to a range of datastores using JDO/JPA/REST APIs. *** Note that code development is no longer on SourceForge (code on SourceForge is for versions up to 3.3.5 only) ***

POJava is a simple, light-weight Java-based API for data processing and development. It includes an immutable DateTime object capable of parsing free-form dates in multiple languages and formats, and a variety of utilities for data transformation.

QueryObjectFactory (QOF) is a lightweight runtime JDBC byte-code generator providing support for CRUD (create, retrieve, update and delete) operations and stored procedure calls. It uses Java annotations to define mappings and is fully OSGi ready.

A powerful 100% JAVA flat file processing ORM framework. Giving the ability to abstract the processing of flat files from business logic, using Hibernate style mapping constructs. Supports fixed length and delimited (e.g CSV) file formats.

Criteria2JPQL API is an adaptation of the powerful Hibernate Criteria API to standard JPA API enabling the compatibility with any orm tool. Against the native SQL queries created by Hibernate Criteria, Criteria2JPQL outputs standard JPQL queries.

This is android library to simplify Android SQlite Database It become very tedious to write large Android SQLite Open helper for simple database usage. So I developed this library to create android databases very easily using straight forward functions.

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

Simple (Easy) Object Relational Mapping for Java Sormula is a Java library that moves data between Java objects and relational database tables. * Easy to Use * Simple to Understand * Minimal Configuration * Portable It provides select, insert, update, and delete, and many other common operations. One-to-one and one-to-many cascading for unlimited levels. Simplified IN operator parameter as java.util.Collection. Custom conversions between any Java class/type and column type. * Works with any relational database. Tested with H2, HSQLDB, Derby, SQLiteJDBC, MySQL, MariaDB, Firebird, DB2, Oracle 11g, PostgreSQL. * Performs as fast as plain JDBC. Performs faster than plain JDBC when caching is enabled. * Zero-configuration, zero-annotation use is possible. * Active record pattern may be used but is not required.
