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) ***
Druid is a GUI tool for database build and management. Users can add/change/delete DB objects (tables, fields, etc). Druid generates for you: SQL scripts, docs in XHTML, PDF, DocBook, etc; code in C, C++ & Java Beans even for JDO and support Castor & OJB
WhiteBear is a set of foundation classes for database engines written in Java. It supports object and relational database, is highly portable and may be used in embedded or server environment. Project has been created from scratch and plan to includes storage engine, server, SQL interpreter, ODBC, JDBC and JDO interface
Cumulus4j is an encryption plug-in for DataNucleus. Applications can thus use JDO or JPA to persist their data into every common database. Using the Bouncy Castle cryptography libs, it provides strong encryption via AES, TwoFish or other algorithms.
New customers can spin up VMs, build with AI, and query data at no cost.
Put your $300 in credit toward real workloads, then keep building with free monthly usage for 20+ products. No commitment and no charge until you upgrade.
A trading platform including ERP, CRM, and accounting
JFire is a trading platform including ERP, CRM, accounting (full double-entry) and cross-organisation-trading written in Java based on J2EE, JDO and the Eclipse RCP. See http://www.jfire.net for more information.
TriActive JDO (TJDO) is an open source implementation of Sun's Java Data Objects (JDO) specification, designed to support transparent persistence using any JDBC-compliant database. It auto-generates DDL and auto-validates DB structure at runtime.
Gaea allows you to view/modify Object Databases with JDO standard. Operations on instances and class structures on the fly. A nigh-complete OQL library is embedded in the project and can easily be used by third-party software to attain OQL compatibility
JDO is a Java DeObfuscator that works on class files directly. JDO contains a simple and easy to use GUI that makes automatic deobfuscation of Java projects a one-click operation!
A simple SQL Query -> Java Object mapping layer. Simpler than Hibernate or JDO, and much lighter weight. Compatible with the JDBC 4, EoD API from Java 6 beta.
Deploy in 115+ regions with the modern database for every enterprise.
MongoDB Atlas gives you the freedom to build and run modern applications anywhere—across AWS, Azure, and Google Cloud. With global availability in over 115 regions, Atlas lets you deploy close to your users, meet compliance needs, and scale with confidence across any geography.
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.
Middlegen is a free general-purpose database-driven code generation engine based on JDBC, Velocity, Ant and XDoclet. If you already have a database, you can use Middlegen to generate EJB (CMP 2.0), Hibernate, JDO and JSP/Struts source code.
If your project demands you to persist java objects in any environment (J2EE etc), use standards but switch to any standards such as JDO, EJB, Hibernate anytime,
use default mapping for build from the scratch apps "EasyPersistence" is your solution
Object Relational Persistence and Object-Based SQL Query API. Similar to that of Hibernate or JDO but much better structured design. This API has several layers of abstraction to be useful for nearly any situation.
This project is a feature-preview tool for JDO with JDK5's annotation usage.
It removes away the step of writing metadata files or modifying them when the model classes are greatly changed. An Ant task is provided to automatically do this step for you.
This Eclipse plugin makes easy and fast to develop transaction applications in Java using JDO drivers. This tool integrates the JDO enhance command in JDT building process.
XORM is an extensible object-relational mapping layer for Java
applications. It provides interface-based persistence to RDBMSs using the Java Data Objects (JDO) API while allowing developers to focus on the object model, not the physical layer.
Java disk/CD/DVD/HD/whatever cataloguer designed to allow the storage and search of different types of data. Hibernate or JDO will be used for catalog storage and maybe some native functions for volume data retrieval (serial and label).
RDBS2J is a GUI based mapping tool from relational database schema to persistent java classes which use JDO as persistence mechanism. The mapping can be modified by the GUI. The current version is designed to create code for Apache-OJB.
AutoSQL provides a simple and easy to use framework meant to be a substitute for J2EE Entity beans and JDO. AutoSQL data objects give just the right abstraction from a writing SQL without being too far removed from the power of SQL.
The Castor Taglib allows you to execute OQL queries in your JSP page
(using Castor JD0). It also helps you to integrate Castor JDO with Java application servers like Tomcat, making use of JNDI and Tyrex for managed transactions. In future releases other
This project contains an component to building JDO applications with Castor (http://castor.exolab.org/). It's allow easy using of mappings with building OQL queries.
Given a set of classes, Struts-Genie generate a complete Object Oriented dynamic web application built with Java Struts, Tiles, JSP ... and Java Data Object (JDO) for object persistence management. Easy to use, to extend and to customize
JellyFish is a toolkit for persisting Java objects to LDAP. Its goals are similar to those of Java Data Objects(JDO), but it targets JNDI instead of JDBC. JellyFish has a built-in filesystem JNDI provider, so you do not need an LDAP server to try it.
