Mirror of: https://github.com/osdldbt/ This Database Test Suite aims to create database workload test kits used to simulate heavy user loads for OLTP, Decision Support, and e-commerce database transactions. These test kits can also be used to gather performance results for Linux and other

C/C++/Java source code library and Build Environment. Contains code for threading, inter-thread communication (ITC), sockets, embedded database, parsing, fileio, etc. The majority of the library is designed for embedded development.

dbXML is a Native XML Database (NXD). NXDs are databases that store XML using an internalized format for faster overall processing. dbXML was developed using the Java 2 Standard Edition version 1.4.

JETHRO (Java Engine for Translating and Hiding Relational to Object) is a "bottom-up" persistence framework, designed in an "API+Provider" fashion. Based on the Data Transfer Object (DTO) concept, it offers a Transparent Query engine.

XML schema to specify relational database administration and operations. Uses XML, XSLT stylesheets and Java code to allow applications to use advance features of databases and have complex queries without being tied to a specific relational database.

The Adept Library contains a lightweight Java Object database for stand-alone applications. It is designed for simplicity of use, exposing a simple DTO - no need for copy logic or complex serialisation techniques. It is also a powerful general library.

Ashpool is a lightweight XML Database written in Java. It is designed to query table like XML documents and has a built in JDBC driver. (Saxon Inside)

Bodega is a distributed objects database framework for AJAX, RIA, REST, SOA, and Web Services.

Project MOVED to Codehaus New location is http://esper.codehaus.org The Esper project aims to provide a general-purpose event processing facility in Java for complex event processing of real-time, high throughput data streams.

A unique persistence layer for Java. CODO (Cursor Oriented Data Objects) maps generated Entity interfaces (suitable for DTOs) to a relational database via rendered SQL, reflection and JDBC Cursors where possible - avoiding associations.

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.

Cayenne is an object-relational mapping framework written in Java. This Cayenne project at SourceForge is dedicated to hosting a legacy 1.2 release. For up to date releases please visit the new home at Apache. http://cayenne.apache.org

The project has been renamed CrNiCKL (chronicle) and moved to http://crnickl.sourceforge.net. ChronoDB is a data manager written in Java. It supports time series of any type. With its simple and powerful schema subsystem it takes charge of very large heterogeneous data sets. The software consist of an API and a generic implementation layer running on top of an SQL or a NoSQL system. Applications can mix objects from multiple ChronoDB databases.

CodaServer is a database that makes building business applications easy. It uses a SQL-like language that lets you describe your workflow and business processes, and uses this information to enforce your business rules and guarantee data integrity.

A framework for building, deploying and managing well-described REST-ful Web services, including REST-ful Web Services realizations for RSS, XML Topic Maps, Structured Arguments, and Workflow.

Data-driven from a simple text file describing the fields you wish to use in your bug database. Perfect for small project teams. <a href="http://www.soft82.com/"><img src="soft82_award_50x81.gif" width="50" height="81" border="0" alt="Free download software"></a>

ConnFarm is a high-performance database connection pool. The feature-set includes idle connection management, timeout controls, connection leak debugging capabilities, and JMX monitoring.

CrNiCKL (pronounced "chronicle") is a data manager written in Java handling large sets of heterogeneous time series. A simple schema system allows to confiture value types and time domains. CrNiCKL runs on top of SQL or NoSQL databases. Drivers for JDBC and MongoDB are available.

DBManager aims to be an Abstraction Layer for JDBC Databases. It hides all Database interaction in the Superclass (DBManager) the Superclass useses the Java reflection framework to gather Informations of Tables and Columns.

Data Manipulator is a pure Java GUI interface for SQL databases. Not only an administrative tool, but one that allows a user to create forms and reports. Additionally A Java programmer can use code with Forms, reports a stand alone to manipulate the data

Datadog is an object persistence layer written in Java. Features include caching, transaction support, and much more using a rich and flexible API. Datadog is a dead project, and has not been updated since 2002. Use Hibernate if you must use Java.
