OpenJPA
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. History Kodo, a Java Data Objects implementation, was originally developed by SolarMetric, Inc in 2001. BEA Systems acquired SolarMetric in 2005, where Kodo was expanded to be an implementation of both the JDO (JSR 12) and JPA (JSR 220) specifications. In 2006, BEA donated a large part of the Kodo source code to the Apache Software Foundation under the name OpenJPA. The donated source code will be the core persistence engine of BEA Weblogic Server, IBM WebSphere, and the Geronimo Application Server. In May 2007, OpenJPA graduated from the incubator to a top-level project and also passed Sun's Technology Compatibility Kit compliant with the Java Persistence API.

Java Persistence API
Jakarta Persistence, also known as JPA (abbreviated from the former name Java Persistence API) is a Jakarta EE application programming interface specification that describes the management of relational data in enterprise Java applications. Persistence in this context covers three areas: * The API itself, defined in the package ( for Jakarta EE 8 and below) * The Jakarta Persistence Query Language (JPQL; formerly Java Persistence Query Language) * Object/relational metadata History The final release date of the JPA 1.0 specification was 11 May 2006 as part of Java Community Process JSR 220. The JPA 2.0 specification was released 10 December 2009 (the Java EE 6 platform requires JPA 2.0). The JPA 2.1 specification was released 22 April 2013 (the Java EE 7 platform requires JPA 2.1). The JPA 2.2 specification was released in the summer of 2017. The reference implementation for JPA 1 and 2 was EclipseLink. Jakarta Persistence 3.1 was released in the spring of 2022 as part of ...

Apache Geronimo
Apache Geronimo is an open source application server developed by the Apache Software Foundation and distributed under the Apache license. Geronimo 3, the current version, is compatible with the Java Enterprise Edition (Java EE) 6 specification and therefore supports technologies such as JMS, Enterprise JavaBeans, Connectors, servlets, JSP, JSF, Unified Expression Language and JavaMail. This allows developers to create enterprise applications that are portable and scalable, and that integrate with legacy technologies. The older Geronimo 2 is compatible with Java EE 5. IBM has in the past provided considerable support to the project through marketing, code contributions, and the funding of several project committers. In October 2005, IBM announced a free edition of its WebSphere application server named Websphere Application Server Community Edition (WASCE), which is actually a distribution of Geronimo and despite its name not related to the commercial WebSphere server.

Apache Software Foundation
The Apache Software Foundation ( ; ASF) is an American nonprofit corporation (classified as a 501(c)(3) organization in the United States) to support a number of open-source software projects. The ASF was formed from a group of developers of the Apache HTTP Server, and incorporated on March 25, 1999. it includes approximately 1000 members. The Apache Software Foundation is a decentralized open source community of developers. The software they produce is distributed under the terms of the Apache License, a permissive open-source license for free and open-source software (FOSS). The Apache projects are characterized by a collaborative, consensus-based development process and an open and pragmatic software license, which is to say that it allows developers, who receive the software freely, to redistribute it under non-free terms. Each project is managed by a self-selected team of technical experts who are active contributors to the project. The ASF is a meritocracy, implying tha ...

Apache Software Foundation Projects
The Apache ( ) are several Southern Athabaskan language-speaking peoples of the Southwest, the Southern Plains and Northern Mexico. They are linguistically related to the Navajo. They migrated from the Athabascan homelands in the north into the Southwest between 1000 and 1500 CE. Apache bands include the Chiricahua, Jicarilla, Lipan, Mescalero, Mimbreño, Salinero, Plains, and Western Apache ( Aravaipa, Pinaleño, Coyotero, and Tonto). Today, Apache tribes and reservations are headquartered in Arizona, New Mexico, Texas, and Oklahoma, while in Mexico the Apache are settled in Sonora, Chihuahua, Coahuila and areas of Tamaulipas. Each tribe is politically autonomous. Historically, the Apache homelands have consisted of high mountains, sheltered and watered valleys, deep canyons, deserts, and the southern Great Plains, including areas in what is now Eastern Arizona, Northern Mexico (Sonora and Chihuahua) and New Mexico, West Texas, and Southern Colorado. These ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NoSQL
NoSQL (originally meaning "Not only SQL" or "non-relational") refers to a type of database design that stores and retrieves data differently from the traditional table-based structure of relational databases. Unlike relational databases, which organize data into rows and columns like a spreadsheet, NoSQL databases use a single data structure—such as key–value pairs, wide columns, graphs, or documents—to hold information. Since this non-relational design does not require a fixed schema, it scales easily to manage large, often unstructured datasets. NoSQL systems are sometimes called ''"Not only SQL"'' because they can support SQL-like query languages or work alongside SQL databases in polyglot-persistent setups, where multiple database types are combined. Non-relational databases date back to the late 1960s, but the term "NoSQL" emerged in the early 2000s, spurred by the needs of Web 2.0 companies like social media platforms. NoSQL databases are popular in big data ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hibernate (framework)
Hibernate ORM (or simply Hibernate) 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. Hibernate is free software that is distributed under the Apache License. Versions prior to 7.0.0.Beta4 were distributed under the GNU Lesser General Public License 2.1. Hibernate's primary feature is mapping from Java classes to database tables, and mapping from Java data types to SQL data types. Hibernate also provides data query and retrieval facilities. It generates SQL calls and relieves the developer from the manual handling and object conversion of the result set. Mapping The mapping of Java classes to database tables is implemented by the configuration of an XML file or by using Java Annotations. When using ...

EclipseLink
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: * Jakarta Persistence (JPA) *Jakarta XML Binding (JAXB) * Jakarta Connectors (JCA) * Service Data Objects (SDO) EclipseLink is based on the TopLink product from which Oracle contributed the source code to create the EclipseLink project. 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 ...

Persistence (computer Science)
In computer science, persistence refers to the characteristic of State (computer science), state of a system that outlives (persists for longer than) the Process (computing), process that created it. This is achieved in practice by storing the state as data in computer data storage. Programs have to transfer data to and from storage devices and have to provide mappings from the native Programming language, programming-language Data structure, data structures to the storage device data structures. Picture editing programs or Word processor, word processors, for example, achieve State (computer science), state persistence by saving their documents to computer file, files. Orthogonal or transparent persistence Persistence is said to be "Orthogonality#Computer science, orthogonal" or "transparent" when it is implemented as an intrinsic property of the execution environment of a program. An orthogonal persistence environment does not require any specific actions by programs running i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Technology Compatibility Kit
A Technology Compatibility Kit (TCK) is a suite of tests that at least nominally checks a particular alleged implementation of a Java Specification Request (JSR) for compliance. It is one of the three required pieces for a ratified JSR in the Java Community Process, which are: *the JSR specification *the JSR reference implementation *the Technology Compatibility Kit (TCK) Contents and architecture TCKs tend to be obtained from the Specification Lead of a given JSR. They usually (but not always) consist of a graphical host application which communicates over TCP/IP with the device or Java virtual machine that is under test. Tests are typically obtained by the device over HTTP, and results are posted back to the host application in a similar way. This decoupling enables TCKs to be used to test virtual machines on devices such as CLDC mobile phones which do not have the power to run the full TCK host application. The tests contained in the JSR are supposedly derived from the statements ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BEA Systems
BEA Systems, Inc. was a company that specialized in enterprise infrastructure software products, which was wholly acquired by Oracle Corporation on April 29, 2008. History BEA began as a software company, founded in 1995 and headquartered in San Jose, California. It grew to have 78 offices worldwide at the time of its acquisition by Oracle. The company's name is an initialism of the first names of the company's three founders: Bill Coleman, Ed Scott, and Alfred Chuang. All were former employees of Sun Microsystems, and launched the business in 1995 by acquiring Information Management and Independence Technologies. These firms were the largest resellers of '' Tuxedo'', a distributed transaction management system sold by Novell. BEA soon acquired the Tuxedo product itself, and went on to acquire other middleware companies and products. In 1998, BEA acquired the San Francisco start-up WebLogic, which had built the first standards-based Java application server. WebLogic's app ...
