Apache Cayenne
Apache Cayenne is an open source persistence framework licensed under the Apache License, providing object-relational mapping (ORM) and remoting services. Cayenne binds one or more database schemas directly to Java objects, managing atomic commit and rollbacks, SQL generation, joins, sequences, and more. With Cayenne's Remote Object Persistence, those Java objects can even be persisted out to clients via Web Services. Or, with native XML serialization, objects can be further persisted to non-Java clients—such as an Ajax-capable browser. Cayenne supports database reverse engineering and generation, as well as a Velocity-based class generation engine. All of these functions can be controlled directly through the CayenneModeler, a fully functional GUI tool. No XML- or annotation-based configuration is required. An entire database schema can be mapped directly to Java objects quickly, all from the comfort of the GUI-based CayenneModeler. These things together make Cayenne interesti ...

Eclipse Distribution License
An eclipse is an astronomical event which occurs when an astronomical object or spacecraft is temporarily obscured, by passing into the shadow of another body or by having another body pass between it and the viewer. This alignment of three celestial objects is known as a ''syzygy''. An eclipse is the result of either an ''occultation'' (completely hidden) or a ''transit'' (partially hidden). A "deep eclipse" (or "deep occultation") is when a small astronomical object is behind a bigger one. "What is a deep eclipse? The smaller star is behind the bigger star" The term ''eclipse'' is most often used to describe either a solar eclipse, when the Moon's shadow crosses the Earth's surface, or a lunar eclipse, when the Moon moves into the Earth's shadow. However, it can also refer to such events beyond the Earth–Moon system: for example, a planet moving into the shadow cast by one of its moons, a moon passing into the shadow cast by its host planet, or a moon passing into the s ...

SQLObject
SQLObject is a Python object-relational mapper between a SQL database and Python objects. It is experiencing community popularity, and forms a part of many applications (e.g., TurboGears). It is very similar to Ruby on Rails' ActiveRecord in operation in that it uses class definitions to form table schemas, and utilizes the language's reflection and dynamism to be useful. SQLObject supports a number of common database backends: included in the distribution are MariaDB, MySQL, PostgreSQL, SQLite, Sybase SQL Server, MaxDB, Microsoft SQL Server and Firebird. The first version of SQLObject was publicly released in October 2002. See also * TurboGears * SQLAlchemy * Storm A storm is any disturbed state of the natural environment or the atmosphere of an astronomical body. It may be marked by significant disruptions to normal conditions such as strong wind, tornadoes, hail, thunder and lightning (a thunderstor ...

SQLAlchemy
SQLAlchemy is an open-source Python library that provides an SQL toolkit (called "SQLAlchemy Core") and an object–relational mapper (ORM) for database interactions. It allows developers to work with databases using Python objects, enabling efficient and flexible database access. Description SQLAlchemy offers tools for database schema generation, querying, and object-relational mapping. Key features include: * A comprehensive embedded domain-specific language for SQL in Python called "SQLAlchemy Core" that provides means to construct and execute SQL queries. * A powerful ORM that allows the mapping of Python classes to database tables. * Support for database schema migrations. * Compatibility with multiple database backends. * Tools for database connection A database connection is a facility in computer science that allows client software to talk to database server software, whether on the same machine or not. A connection is required to send commands and receive answers, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Redbean (software)
RedBeanPHP is an independent, free, BSD licensed, open-source object–relational mapping (ORM) software written by Gabor de Mooij. It is a stand-alone library, not part of any framework. RedBeanPHP is an on-the-fly object–relational mapper, this means there is no upfront configuration. The system relies on conventions entirely and adapts the database schema to fit the needs of the program. This way, it strikes a balance between NoSQL and traditional RDBMS solutions. Features RedBeanPHP is different from other ORM systems because it requires no configuration in XML, YAML or JSON. It adapts the database schema based on the needs of the program. All tables and columns are created on-the-fly, without upfront configuration or mapping. It automatically adds columns to tables if necessary and changes the type of the column to match its content requirements. When the developer is done developing and no more schema changes are expected, the schema can be frozen for deployment to pro ...

NHibernate
NHibernate is a port of the Hibernate object–relational mapping (ORM) framework for the Microsoft .NET platform. It provides a framework for mapping an object-oriented domain model to a traditional relational database. It is used to map an object-oriented domain model to a relational database, aiming to reduce the amount of manual coding required for data persistence. NHibernate is free and open-source software, distributed under the GNU Lesser General Public License. Feature summary NHibernate's primary feature is mapping from .NET classes to database tables (and from CLR data types to SQL data types). NHibernate provides data query and retrieval tools. It generates the SQL commands and removes the need of manual data set handling and object conversion, keeping the application portable to most SQL databases, with database portability delivered at very little performance overhead. NHibernate provides transparent persistence for Plain Old CLR Objects (POCOs). The only s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Java Object Oriented Querying
jOOQ Object Oriented Querying, commonly known as jOOQ, is a light database-mapping software library in Java that implements the active record pattern. Its purpose is to be both relational and object oriented by providing a domain-specific language to construct queries from classes generated from a database schema. Paradigm jOOQ claims that SQL should come first in any database integration. Thus, it does not introduce a new textual query language, but rather allows for constructing plain SQL from jOOQ objects and code generated from a database schema. jOOQ uses JDBC to call the underlying SQL queries. While it provides abstraction on top of JDBC, jOOQ does not have as much functionality and complexity as standard object–relational mapping libraries such as EclipseLink or Hibernate. jOOQ's closeness to SQL has advantages over typical object–relational mapping libraries. SQL has many features that cannot be used in an object oriented programming paradigm; this set of di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cross-platform
Within computing, cross-platform software (also called multi-platform software, platform-agnostic software, or platform-independent software) is computer software that is designed to work in several Computing platform, computing platforms. Some cross-platform software requires a separate build for each platform, but some can be directly run on any platform without special preparation, being written in an interpreted language or compiled to portable bytecode for which the Interpreter (computing), interpreters or run-time packages are common or standard components of all supported platforms. For example, a cross-platform application software, application may run on Linux, macOS and Microsoft Windows. Cross-platform software may run on many platforms, or as few as two. Some frameworks for cross-platform development are Codename One, ArkUI-X, Kivy (framework), Kivy, Qt (software), Qt, GTK, Flutter (software), Flutter, NativeScript, Xamarin, Apache Cordova, Ionic (mobile app framework ...

IBATIS
iBATIS is a persistence framework which automates the mapping between SQL databases and objects in Java, .NET, and Ruby on Rails. In Java, the objects are POJOs (Plain Old Java Objects). The mappings are decoupled from the application logic by packaging the SQL statements in XML configuration files. The result is a significant reduction in the amount of code that a developer needs to access a relational database using lower level APIs like JDBC and ODBC. Other persistence frameworks such as Hibernate allow the creation of an object model (in Java, say) by the user, and create and maintain the relational database automatically. iBATIS takes the reverse approach: the developer starts with a SQL database and iBATIS automates the creation of the Java objects. Both approaches have advantages, and iBATIS is a good choice when the developer does not have full control over the SQL database schema. For example, an application may need to access an existing SQL database used by other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MyBatis
MyBatis is a Java persistence framework that couples objects with stored procedures or SQL statements using an XML descriptor or annotations. MyBatis is free software that is distributed under the Apache License 2.0. MyBatis is a fork of iBATIS 3.0 and is maintained by a team that includes the original creators of iBATIS. Feature summary Unlike ORM frameworks, MyBatis does not map Java objects to database tables but Java methods to SQL statements. MyBatis lets you use all your database functionality like stored procedures, views, queries of any complexity and vendor proprietary features. It is often a good choice for legacy or de-normalized databases or to obtain full control of SQL execution. It simplifies coding compared to JDBC. SQL statements are executed with a single line. MyBatis provides a mapping engine that maps SQL results to object trees in a declarative way. SQL statements can be built dynamically by using a built-in language with XML-like syntax or with Apach ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GNU Lesser General Public License
The GNU Lesser General Public License (LGPL) is a free-software license published by the Free Software Foundation (FSF). The license allows developers and companies to use and integrate a software component released under the LGPL into their own (even proprietary) software without being required by the terms of a strong copyleft license to release the source code of their own components. However, any developer who modifies an LGPL-covered component is required to make their modified version available under the same LGPL license. For proprietary software, code under the LGPL is usually used in the form of a shared library, so that there is a clear separation between the proprietary and LGPL components. The LGPL is primarily used for software libraries, although it is also used by some stand-alone applications. The LGPL was developed as a compromise between the strong copyleft of the GNU General Public License (GPL) and more permissive licenses such as the BSD licenses and the MI ...
