EclipseLink is the open source Eclipse Persistence Services Project from the Eclipse Foundation. The software provides an extensible framework that allows Java developers to interact with various data services, including databases, web services, Object XML mapping (OXM), and enterprise information systems (EIS). EclipseLink supports a number of persistence standards including:
EclipseLink is based on the TopLink product from which Oracle contributed the source code to create the EclipseLink project. [2] The original contribution was from TopLink's 11g code base, and the entire code-base/feature set was contributed, with only EJB 2 Container-Managed Persistence (CMP) and some minor Oracle Application Server specific integration removed. This differs from the TopLink Essentials GlassFish contribution, which did not include some key enterprise features. The package names were changed and some of the code and configuration was moved around.
The TopLink Mapping Workbench user interface has also been contributed to the project.
EclipseLink is the intended path forward for persistence for Oracle and TopLink. It is intended that the next major release of Oracle TopLink will include EclipseLink as well as the next major release of Oracle Application Server.
EclipseLink supports usage in an OSGi environment.
Sun Microsystems has selected the EclipseLink project to be the reference implementation for JPA 2.0., [3] Oracle did the same for JPA 2.1 and later JPA specifications. [4]
Jakarta Enterprise Beans is one of several Java APIs for modular construction of enterprise software. EJB is a server-side software component that encapsulates business logic of an application. An EJB web container provides a runtime environment for web related software components, including computer security, Java servlet lifecycle management, transaction processing, and other web services. The EJB specification is a subset of the Java EE specification.
Jakarta EE, formerly Java Platform, Enterprise Edition and Java 2 Platform, Enterprise Edition (J2EE), is a set of specifications, extending Java SE with specifications for enterprise features such as distributed computing and web services. Jakarta EE applications are run on reference runtimes, which can be microservices or application servers, which handle transactions, security, scalability, concurrency and management of the components they are deploying.
Java Data Objects (JDO) is a specification of Java object persistence. One of its features is a transparency of the persistence services to the domain model. JDO persistent objects are ordinary Java programming language classes (POJOs); there is no requirement for them to implement certain interfaces or extend from special classes. JDO 1.0 was developed under the Java Community Process as JSR 12. JDO 2.0 was developed under JSR 243 and was released on May 10, 2006. JDO 2.1 was completed in Feb 2008, developed by the Apache JDO project. JDO 2.2 was released in October 2008. JDO 3.0 was released in April 2010.
A web container is the component of a web server that interacts with Jakarta Servlets. A web container is responsible for managing the lifecycle of servlets, mapping a URL to a particular servlet and ensuring that the URL requester has the correct access-rights. A web container handles requests to servlets, Jakarta Server Pages (JSP) files, and other types of files that include server-side code. The Web container creates servlet instances, loads and unloads servlets, creates and manages request and response objects, and performs other servlet-management tasks. A web container implements the web component contract of the Jakarta EE architecture. This architecture specifies a runtime environment for additional web components, including security, concurrency, lifecycle management, transaction, deployment, and other services.
WebObjects is a discontinued Java web application server and a server-based web application framework originally developed by NeXT Software, Inc.
Jakarta XML Binding is a software framework that allows Java EE developers to map Java classes to XML representations. JAXB provides two main features: the ability to marshal Java objects into XML and the inverse, i.e. to unmarshal XML back into Java objects. In other words, JAXB allows storing and retrieving data in memory in any XML format, without the need to implement a specific set of XML loading and saving routines for the program's class structure. It is similar to xsd.exe
and XmlSerializer
in the .NET Framework.
In software, a data access object (DAO) is a pattern that provides an abstract interface to some type of database or other persistence mechanism. By mapping application calls to the persistence layer, the DAO provides data operations without exposing database details. This isolation supports the single responsibility principle. It separates the data access the application needs, in terms of domain-specific objects and data types, from how these needs can be satisfied with a specific DBMS.
Hibernate ORM is an object–relational mapping tool for the Java programming language. It provides a framework for mapping an object-oriented domain model to a relational database. Hibernate handles object–relational impedance mismatch problems by replacing direct, persistent database accesses with high-level object handling functions.
In computing, Oracle Application Development Framework, usually called Oracle ADF, provides a Java framework for building enterprise applications. It provides visual and declarative approaches to Java EE development. It supports rapid application development based on ready-to-use design patterns, metadata-driven and visual tools.
GlassFish is an open-source Jakarta EE platform application server project started by Sun Microsystems, then sponsored by Oracle Corporation, and now living at the Eclipse Foundation and supported by OmniFish, Fujitsu and Payara. The supported version under Oracle was called Oracle GlassFish Server. GlassFish is free software and was initially dual-licensed under two free software licences: the Common Development and Distribution License (CDDL) and the GNU General Public License (GPL) with the Classpath exception. After having been transferred to Eclipse, GlassFish remained dual-licensed, but the CDDL license was replaced by the Eclipse Public License (EPL).
The Spring Framework is an application framework and inversion of control container for the Java platform. The framework's core features can be used by any Java application, but there are extensions for building web applications on top of the Java EE platform. The framework does not impose any specific programming model.. The framework has become popular in the Java community as an addition to the Enterprise JavaBeans (EJB) model. The Spring Framework is free and open source software.
Jakarta Persistence, also known as JPA is a Jakarta EE application programming interface specification that describes the management of relational data in enterprise Java applications.
OpenJPA is an open source implementation of the Java Persistence API specification. It is an object-relational mapping (ORM) solution for the Java language, which simplifies storing objects in databases. It is open-source software distributed under the Apache License 2.0.
Configurable Network Computing or CNC is JD Edwards's (JDE) client–server proprietary architecture and methodology. Now a division of the Oracle Corporation, Oracle continues to sponsor the ongoing development of the JD Edwards Enterprise Resource Planning (ERP) system, While highly flexible, the CNC architecture is proprietary and, as such, it cannot be exported to any other systems. While the CNC architecture's chief 'Claim to fame', insulation of applications from the underlying database and operating systems, were largely superseded by modern web-based technology, nevertheless CNC technology continues to be at the heart of both JD Edwards' One World and Enterprise One architecture and is planned to play a significant role Oracle's developing fusion architecture initiative. While a proprietary architecture, CNC is neither an Oracle nor JDE product offering. The term CNC also refers to the systems analysts who install, maintain, manage and enhance this architecture. CNC's are also one of the three technical areas in the JD Edwards Enterprise Resource Planning ERP which include developer/report writer and functional/business analysts.
Apache ObJectRelationalBridge (OJB) is an Object/Relational mapping tool that allows transparent persistence for Java Objects against relational databases. It was released on April 6, 2005.
JBoss Developer Studio (JBDS) is a development environment created and currently developed by JBoss and Exadel.
DataNucleus is an open source project which provides software products around data management in Java. The DataNucleus project started in 2008.
Oracle TopLink is a mapping and persistence framework for Java developers. TopLink is produced by Oracle and is a part of Oracle's OracleAS, WebLogic, and OC4J servers. It is an object-persistence and object-transformation framework. TopLink provides development tools and run-time functionalities that ease the development process and help increase functionality. Persistent object-oriented data is stored in relational databases which helps build high-performance applications. Storing data in either XML or relational databases is made possible by transforming it from object-oriented data.
