Open Source Object Oriented Software

db4o is the world's leading open source object database for Java and .NET. Leverage fast native object persistence, ACID transactions, query-by-example, S.O.D.A object query API, automatic class schema evolution, small size (http://developer.db4o.com)

JoSQL (Java Objects SQL) provides SQL capabilities for querying, ordering and grouping of collections of Java objects (POJOs). It allows a SQL statement to be applied to the collection of objects and the matching set returned, ordered and grouped.

A complete, fast, previously commercial, JDO 1.0.1 implementation for databases, opened by Versant in 2005 and then abandoned in early 2006. The design-time code is already in Eclipse Dali. This project is the original source drop, including the runtime.

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

JXmlSql is a Java database API ( MySql, Oracle, Access )that eliminates JDBC code. JXmlSql allows developers to define application and prepopulation SQL statements inside xml files. Options for query, insert, update, delete, report and prepopulation SQL.

JPOX was an Apache2 licensed standards-driven Java persistence implementation. It is replaced by DataNucleus http://www.datanucleus.org

PHPersistencia is a database persistence layer for PHP, offering Object Oriented interface to access the data, generating sql queries transparently for insert/update, selecting data as object collection and verifing data types without database access

Php Object Generator is an open source PHP code generator which generates clean & tested Object Oriented code for your PHP4/PHP5 application. By generating PHP objects with integrated CRUD methods, POG gives you a head start in any project.

Abstracts developers from SQL syntax, with methods that return Strings to pass on to JDBC, thus allowing compile-time checking for, many, otherwise run-time bugs. e.g. stmt.executeQuery(SqlWrapper.selectId(ordersTable, customerColumn, "John Smith")

A well designed and portable SQLite wrapper library for C++ You're welcome to make suggestions for design improvements. Feature requests are welcome too.

BizBlox is a simple to use Object Relational Mapper API for .Net. On top of the usual features you expect from an ORM it provides native support for web services using transfer objects and partial transfer objects.

Bridge To Babylon is a java object relational mapper (java ORM). It is intended to be lightweight and easy to use.

BuzzSQL is a thin layer over Java JDBC that manages automatic configuration of database connection setup, pooling, configuration, logging, and statement handling.

Catnap is a lightweight Java persistence layer which stores and retrieves objects from an Oracle database using PL/SQL packages.

.NET library (written in C#) for developers writing data access code that is less cumbersome than straight ADO.NET and is almost entirely database platform independent for most database platforms.

Data Access Objects for PHP5. A set of classes used for connecting to databases in PHP5. The goal is to provide PHP5 developers with a unified OO API to access databases.

That project aims at providing a framework for SOCI (http://soci.sourceforge.net), so as to ease the packaging and delivery processes, allowing to deliver packages for a great number of Linux distributions, as well as for other Unices and MS Windows.

The Harmoni PHP Project consists of three major components: 1) A PHP application framework and architecture, offering, e.g. authentication, DBC, file storage 2) PHP OKI OSID (service definitions) conversion system 3) PHP implementations of those OSIDs
