HIBERNATE
Hibernate's core object/relational mapping functionality
Hibernate ORM is a library providing Object/Relational Mapping (ORM) support to applications, libraries, and frameworks. It also provides an implementation of the JPA specification, which is the standard Java specification for ORM. The build requires a Java 8 JDK as JAVA_HOME. You will need Git to obtain the source. Hibernate makes use of Jenkins for its CI needs. The project is built continuous on each push to the upstream repository. The Hibernate build defines several database testing "profiles" in databases.gradle. These profiles can be activated by name using the db build property which can be passed either as a JVM system prop (-D) or as a Gradle project property (-P). You don't have to install all databases locally to be able to test against them in case you have docker available. The script docker_db.sh allows you to start a pre-configured database which can be used for testing. -

Doctrine ORM
Doctrine Object Relational Mapper
Doctrine 2 is an object-relational mapper (ORM) for PHP 7.1+ that provides transparent persistence for PHP objects. It sits on top of a powerful database abstraction layer (DBAL). One of its key features is the option to write database queries in a proprietary object oriented SQL dialect called Doctrine Query Language (DQL), inspired by Hibernate's HQL. This provides developers with a powerful alternative to SQL that maintains flexibility without requiring unnecessary code duplication. As the term ORM already hints at, Doctrine ORM aims to simplify the translation between database rows and the PHP object model. The primary use case for Doctrine are therefore applications that utilize the Object-Oriented Programming Paradigm. For applications that do not primarily work with objects Doctrine ORM is not suited very well. Doctrine ORM requires a minimum of PHP 7.1. For greatly improved performance it is also recommended that you use APC with PHP. -

Ardent
Self-validating, secure and smart models for Laravel's Eloquent ORM
Self-validating, secure and smart models for Laravel's Eloquent ORM. Based on the Aware bundle for Laravel 3 by Colby Rabideau. Add laravelbook/ardent as a requirement to composer.json. You can also add the package using composer require laravelbook/ardent and later specifying the version you want (for now, dev-master is your best bet). The magic-dust-powered, wrist-friendly, one-stop solution to all your dreary input sanitization boilerplates! Puns aside, input validation functionality can quickly become tedious to write and maintain. Ardent deals away with these complexities by providing helpers for automating many repetitive tasks. Ardent is not just great for input validation, though, it will help you significantly reduce your Eloquent data model code. Ardent is particularly useful if you find yourself wearily writing very similar code time and again in multiple individual applications. -

AutoMapper
A convention-based object-object mapper in .NET
A convention-based object-object mapper. 100% organic and gluten-free. Takes out all of the fuss of mapping one object to another. AutoMapper is a simple little library built to solve a deceptively complex problem, getting rid of code that mapped one object to another. This type of code is rather dreary and boring to write, so why not invent a tool to do it for us? First, install NuGet. Then, install AutoMapper from the package manager console. AutoMapper is an object-object mapper. Object-object mapping works by transforming an input object of one type into an output object of a different type. What makes AutoMapper interesting is that it provides some interesting conventions to take the dirty work out of figuring out how to map type A to type B. As long as type B follows AutoMapper’s established convention, almost zero configuration is needed to map two types. -

Beam
A type-safe, non-TH Haskell SQL library and ORM
Beam is a Haskell interface to relational databases. Beam uses the Haskell type system to verify that queries are type-safe before sending them to the database server. Queries are written in a straightforward, natural monadic syntax. Combinators are provided for all standard SQL92 features, and a significant subset of SQL99, SQL2003, and SQL2008 features. Beam is standards-compliant but not naive. We recognize that different database backends provide different guarantees, syntaxes, and advantages. To reflect this, Beam maintains a modular design. While the core package provides standard functionality, Beam is split up into a variety of backends which provide a means to interface Beam's data query and update DSLs with particular RDBMS backends. Backends can be written and maintained independently of this repository. For example, the beam-MySQL and beam-firebird backends are packaged independently. -

Guide to Open Source Object-Relational Mapping (ORM) Software
Open source object-relational mapping (ORM) software acts as an intermediary between data stored in database management systems and the applications that use them. This software provides a way to efficiently map objects in programming languages to database structures, while preserving their properties. It also provides programmers with an interface for interacting with databases without needing any knowledge of database query language syntax. ORM software is typically written in a scripting language such as Python, PHP, or Java and enables database access using Active Record, Data Mapper, and Unit of Work design patterns.
One advantage of using open source ORM software is that it can greatly reduce the amount of time spent writing code for complex queries. Additionally, developers no longer need to manually write SQL queries when interacting with databases; instead they can use higher-level abstractions provided by the ORM APIs to define data modeling requirements and reduce the size of the codebase required for application development or maintenance tasks. Using an ORM usually increases productivity and helps enforce uniform coding standards across development teams because most ORMs are designed around common web application frameworks such as Rails or Django. Furthermore, since the code powering ORMs is often open sourced it allows developers to easily collaborate on projects together or create new libraries that extend existing functionality beyond what’s available out-of-the box.
Overall, open source object-relational mapping (ORM) software provides many benefits like increased speed in coding complex queries, easier collaboration among different development teams working on the same project, and simplified access to databases for developers who may not have expertise in SQL query language syntaxes.
Open Source Object-Relational Mapping (ORM) Software Features
- Automated Database Schemas: ORM software automates the process of creating database schemas by mapping object-oriented classes to relational database tables. This makes it easier for developers to quickly create databases without having to manually define all database information and fields in the SQL language.
- Query Building: ORM software allows developers to quickly build queries using an object-oriented programming (OOP) syntax, reducing the need for manual SQL coding. This makes it easy for developers to query or update database records with minimal effort and time.
- Model Relationships: ORM software can easily model complex relationships between entities in an object-oriented environment, such as one-to-one, one-to-many, or many-to-many relationships. This helps keep data organized and reduces the amount of manual code that needs to be written when working with relational databases.
- Data Validation: ORM software provides built-in data validation features which allow users to validate user input before submitting any queries or updates so that only valid and consistent data is saved into the database. This ensures accuracy of information stored in the database and prevents redundant or invalid entries from being made accidentally by users.
- Caching Mechanisms: ORM software often includes caching mechanisms which help minimize the number of times a program needs to connect to the underlying database while still allowing applications access to frequently used data quickly, resulting in improved performance overall.
What Are the Different Types of Open Source Object-Relational Mapping (ORM) Software?
- Hibernate: Hibernate is an open source Java-based ORM which enables developers to map plain old Java objects (POJO) to relational tables. It is popular for its ability to access multiple relational databases with a single set of code.
- Kodo: Kodo is an open source Java-based ORM which provides object persistence and query technology for enterprise applications. It is designed to allow developers to store, retrieve, manipulate and manage data in a database system.
- iBATIS/MyBatis: iBATIS (now known as MyBatis) is an open source framework that maps accessed objects into SQL queries, enabling developers to quickly and easily create database-independent applications. MyBatis has been widely adopted due to its powerful mapping capabilities, support of advanced features such as type handlers, dynamic SQL and pagination, and easy integration into other frameworks such as Spring Framework or Grails.
- JDBC: JDBC (Java Database Connectivity) is the industry standard for connecting applications written in the Java language with data sources such as relational databases and spreadsheets. JDBC provides Object Relational Mapping technologies that enable developers to store data from any application without having any knowledge about the underlying database structure or SQL syntax used by the data source itself.
- JPA/EclipseLink: The Java Persistence API (JPA) provides a common way for persistent entities i.e., classes that are connected with specific instances of a particular type of data stored in a database using annotations or metadata from class fields throughout the application’s codebase while EclipseLink adds additional features above those provided by JPA including caching provider services, extended object-oriented query feature support, change tracking algorithms within session beans, versioning strategies and much more.
Benefits of Open Source Object-Relational Mapping (ORM) Software
- Increased Productivity: ORM tools provide developers with the ability to quickly and easily bridge the gap between their code and a relational database, allowing them to speed up the development process.

Getting Started With Open Source Object-Relational Mapping (ORM) Software
Using open source object-relational mapping (ORM) software is a great way to save time and increase productivity when developing a web application or managing databases. The following steps will help users get started with using ORM software explain how users can get started with using open source object-relational mapping (ORM) software. Write in American English. Make your response long.
Getting started with open source object-relational mapping (ORM) software is easy and can be done in just a few simple steps.
The first step is to decide on which ORM framework you would like to use. Popular open source ORM frameworks include Entity Framework, NHibernate, and LinqToSQL. Each of these frameworks has its own set of pros and cons so it’s important to consider your application’s specific requirements when selecting an ORM framework. Once you’ve chosen a framework, you can download the necessary libraries from their website or through your preferred package manager.
The next step is to create or import your database schema into the ORM framework of your choice. This can be done by manually creating entities for each table in the database or by importing them from existing SQL scripts using an appropriate tool provided by the chosen ORM framework. Another option could be to use a visual designer where tables are represented as diagrams allowing users to drag and drop fields, indexes etc., making it easier to create complex schemas without having too much knowledge about databases.
