Open Source Java Frameworks

Make AI-driven decisions using your data, in real-time. At any scale, with unbeatable performance. Vespa is a full-featured text search engine and supports both regular text search and fast approximate vector search (ANN). This makes it easy to create high-performing search applications at any scale, whether you want to use traditional techniques or a modern vector-based approach. You can even combine both approaches efficiently in the same query, something no other engine can do. Recommendation, personalization and targeting involves evaluating recommender models over content items to select the best ones. Vespa lets you build applications which does this online, typically combining fast vector search and filtering with evaluation of machine-learned models over the items. This makes it possible to make recommendations specifically for each user or situation, using completely up to date information.

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.

2 Java frameworks with transient and persistent object models based on nonstandard approach (less evident but faster development): an object is a set of named fields. 3 non-object libraries simplifying access to tables stored in RDB, text files, etc.

BackApps is an innovative service designed for smart phones applications developers that allows data sharing between application users.

Server-JEE is the server side functionality of BackApps service that serves the BackApps website.

BackApps Server-OSGi is the back end server of the BackApps service that supplies all the functionality of the mobile applications in the BackApps realm

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

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.

Persistence Framework for Java with no JDBC or SQL knowlege needed. An easy to use Administration GUI is provided to hook into almost any database. No XML configuration mapping files! Easiest Java Database layer out there period.

EmbedDB is a set of simple APIs for interacting with embedded databases in an intuitive fashion. It aims to implement each language binding in an identical way, enforcing binary compatibility, and leveraging the host language's standard structural types

FLEISS Frameworks is a set of programming, instrumental, application, and system frameworks to develop a free software system within an organization either non-commercial or commercial, but primarily scoping on business organizations.

Farrago is an extensible data management framework with a hybrid Java/C++/UML architecture. It is developed as a sub-project of The Eigenbase Project.

The Genomic Diversity and Phenotype Connection (GDPC) written in JAVA uses web services to make XML formatted data publicly available. The GDPC Browser (front-end GUI) can access these services, and other applications can use the API.

The JProgress project provides tools for connectivity with Java clients and the Progress database. JProgress provides an n-tier software architecture for database access for executing remote requests over WANs and the Internet.

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.

Java Object and Relation Persistence framework. No mapping configuration needed! Automatic mapping of object relations, inheritance, arrays ++. Also includes a DB-version migration framework. Powerful, yet easy to use.

Objective database abstraction layer (ODAL) is a high-performance database manipulation framework. Features include query API, O-R mapping, data validation/conversion, stored procedure support, code generation. Minimal dependencies. Short startup time.

Open-jACOB is a rapid application development tool base on Eclipse that enables the development of RichInternetApplications that are based entirely on Java. Open-jACOB application can be deployed as a stand alone app's in a Web container like Tomcat.

BaseMovil is a framework for fast development of J2ME applications: a powerful J2ME database engine, a scripting engine and an ui toolkit which is fully integrated with both and allows xml view definition. The framework handles device differences/bugs.

Salto Persistence is a object/relational persistence framework for a J2EE environment. It comes with Salto-db generator which uses a templates mechanism to generate Salto-db Dataobjects from any existing JDBC-supported Database.

Persistence framework.

The Eigenbase Project is an open-source platform for building advanced data management systems, and is backed by a non-profit organization which designs, develops, and promotes it.

Strong Typed HTML/XML Web framework and embedded database for Java.

The dotSesame project is a C# port of the Sesame project, which is originally written in Java. It is an open source RDF database with support for RDF Schema inferencing and querying. Full documentation of Sesame can be found at http://www.openrdf.org/
