Primer CSS
The CSS design system that powers GitHub
Our goal is to create a system that enables us to build consistent user experiences with ease, yet with enough flexibility to support the broad spectrum of GitHub websites. This goal is embedded in our design and code decisions. Our approach to CSS is influenced by Object-Oriented CSS principles, functional CSS, and BEM architecture. Styles can be mixed and matched to achieve many different layouts, independent of their location. These styles fall into three categories. Single-purpose, immutable styles, that do one thing well. Abstracted patterns for frequently used visual styles. Primer CSS is built upon systems that form the foundation of our styles such as spacing, typography, and color. This systematic approach helps ensure our styles are consistent and interoperable with each other. The base-8 spacing scale is highly composable and works with the density of GitHub’s content. Margin and padding spacers bring consistency to vertical and horizontal rhythm. -

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. -

Laravel Doctrine ORM
A drop-in Doctrine ORM 2 implementation for Laravel 5+
Doctrine 2 is an object-relational mapper (ORM) for PHP that provides transparent persistence for PHP objects. It uses the Data Mapper pattern at the heart, aiming for a complete separation of your domain/business logic from the persistence in a relational database management system. The benefit of Doctrine for the programmer is the ability to focus on object-oriented business logic and worry about persistence only as a secondary problem. This doesn’t mean persistence is downplayed by Doctrine 2, however, it is our belief that there are considerable benefits for object-oriented programming if persistence and entities are kept separated. -

Sequelize
A promise-based multi SQL dialect Node.js ORM
Sequelize is a promise-based Node.js ORM for Postgres, MySQL, MariaDB, SQLite and Microsoft SQL Server. It features solid transaction support, relations, eager and lazy loading, read replication and more. Sequelize follows SEMVER. Supports Node v6 and above to use ES6 features. Sequelize v5 was released on March 13, 2019. Official TypeScript typings are now included. Sequelize can be used since the beginning in order to automate the creation of every table in your database. Models are the essence of Sequelize. A model is an abstraction that represents a table in your database. In Sequelize, it is a class that extends Model. The model tells Sequelize several things about the entity it represents, such as the name of the table in the database and which columns it has (and their data types). -

RepoDB
A hybrid ORM library for .NET.
RepoDB is an open-source .NET ORM library that bridges the gaps of micro-ORMs and full-ORMs. It helps you simplify the switch-over of when to use the BASIC and ADVANCE operations during the development. Like with any other ORMs, RepoDB does provide the preliminary methods needed for your basic operations. The good thing is, it also does provide the operations that are needed to cater your edge-cases like 2nd-Layer Cache, Tracing, Repositories, Property Handlers, and Batch/Bulk Operations. If you are to use RepoDB, your development experience is as simple as opening a connection and calling the advanced operations with a very minimal code. It is the reason that makes this library the simplest ORM to use. When you do the bulk operations, the generated value of the identity columns will be set back to the data models, just right after your execution. It is an important use-case that is/may needed by you and/or most developers. -

SQLBoiler
Generate a Go ORM tailored to your database schema
SQLBoiler is a tool to generate a Go ORM tailored to your database schema. It is a "database-first" ORM as opposed to "code-first" (like gorm/gorp). That means you must first create your database schema. Please use something like sql-migrate or some other migration tool to manage this part of the database's life-cycle. While attempting to migrate a legacy Rails database, we realized how much ActiveRecord benefited us in terms of development velocity. Coming over to the Go database/sql package after using ActiveRecord feels extremely repetitive, super long-winded and down-right boring. Being Go veterans we knew the state of ORMs was shaky, and after a quick review we found what our fears confirmed. Most packages out there are code-first, reflect-based and have a very weak story around relationships between models. Work with existing databases: Don't be the tool to define the schema, that's better left to other tools. -

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.
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.
- Reduced Maintenance Costs: By abstracting away many of the complexities associated with relational databases, ORM software significantly reduces the amount of time needed for maintenance tasks. This leads to lower long-term costs and fewer headaches for developers.
- Safer Code: ORM software offers a better way of keeping your code safe from SQL injection attacks. By creating queries programmatically and relying on parameterized stored procedures, it’s much easier to prevent malicious code from being injected into your application’s database.
- Improved Performance: Many ORMs offer features such as object caching and query optimization that can drastically improve application performance without requiring any manual tweaking from developers.
- Easier Customization: Because most ORMs are written in an open source environment, they can be easily customized and adjusted according to specific needs without having to rewrite large amounts of code. This makes it simpler for developers to add new features or apply customizations as required.
Who Uses Open Source Object-Relational Mapping (ORM) Software?
- Web Developers: Those who develop websites and web applications can use ORM software to quickly create databases and maintain relationships between objects.

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.
