    Hibernate

    Hibernate

    An object relational-mapping (ORM) library for Java

    The Hibernate projects offer a suite of powerful Java libraries to work with data. It is best known for Hibernate ORM, which provides relational persistence for Java models and is an implementation of the Jakarta Persistence specification. Hibernate projects do not consistently release binaries or documentation to SourceForge anymore. For up-to-date information, refer to the Hibernate website: * Hibernate ORM: https://hibernate.org/orm/ * Hibernate Validator: https://hibernate.org/validator/ * Hibernate Search: https://hibernate.org/search/ That website will also be updated with newer projects, such as Hibernate Reactive.

    Prisma

    Prisma

    Next-generation ORM for Node.js and TypeScript

    Prisma helps app developers build faster and make fewer errors with an open source ORM for PostgreSQL, MySQL and SQLite. Central to Prisma is the schema, a declarative way to define your app's data models and their relations that's human-readable. And you don't have to painstakingly create it from scratch if you already have a database - prisma introspect takes care of that. Prisma Client is a query builder that composes the way you think and gets auto-generated from the Prisma schema with types tailored to your app. We designed the API to be intuitive for both SQL veterans and people brand new to databases. Auto-completion, linting, formatting and more help Prisma developers in VSCode stay confident without distractions. Prisma Client puts extra emphasis on extensive type safety for more productive development in TypeScript. Prisma is a server-side library that helps your app read and write data to the database in an intuitive and safe way.

    Doctrine ORM

    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.

    AutoMapper

    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.

    Diesel

    Diesel

    A safe, extensible ORM and Query Builder for Rust

    Diesel is the most productive way to interact with databases in Rust because of its safe and composable abstractions over queries. We don’t want to waste time tracking down runtime errors. We achieve this by having Diesel eliminate the possibility of incorrect database interactions at compile time. Diesel offers a high level query builder and lets you think about your problems in Rust, not SQL. Our focus on zero-cost abstractions allows Diesel to run your query and load your data even faster than C. Unlike Active Record and other ORMs, Diesel is designed to be abstracted over. Diesel enables you to write reusable code and think in terms of your problem domain and not SQL.

    greenDAO

    greenDAO

    Light ORM solution for Android that maps objects to SQLite databases

    Android ORM for your SQLite database. For new apps we recommend ObjectBox, a new object-oriented database that is much faster than SQLite and easier to use. For existing apps based on greenDAO we offer DaoCompat for an easy switch (see also the announcement). greenDAO is an open source Android ORM making development for SQLite databases fun again. It relieves developers from dealing with low-level database requirements while saving development time. SQLite is an awesome embedded relational database. Still, writing SQL and parsing query results are quite tedious and time-consuming tasks. greenDAO frees you from these by mapping Java objects to database tables (called ORM, “object/relational mapping”). This way you can store, update, delete, and query for Java objects using a simple object oriented API. We want to provide the fastest Android ORM.

    peewee

    peewee

    A small, expressive orm, which supports postgresql, mysql and sqlite

    Peewee is a simple and small ORM. It has few (but expressive) concepts, making it easy to learn and intuitive to use. Peewee will automatically infer the database table name from the name of the class. You can override the default name by specifying a table_name attribute in the inner “Meta” class (alongside the database attribute). To learn more about how Peewee generates table names, refer to the Table Names section. There are lots of field types suitable for storing various types of data. Peewee handles converting between pythonic values and those used by the database, so you can use Python types in your code without having to worry. The real strength of our database is in how it allows us to retrieve data through queries. Relational databases are excellent for making ad-hoc queries. Peewee provides a magical helper fn(), which can be used to call any SQL function.
