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. -

Ebean
Ebean ORM
Ebean provides multiple levels of query abstraction ORM Queries, mixed with SQL, DTO Queries, SqlQuery and JDBC. Work at the highest level of abstraction and drop down levels as needed. Built in DB migration generation and running. Support for "rebase" migrations as well as repeatable, init and 'normal' migrations. Ebean produces SQL that you would hand craft yourself. Use great SQL, never generate SQL cartesian product, always honor relational limit/offset. For ORM queries Ebean can profile the object graph being used and either automatically tune the query. Docker test containers for all the supported databases. Get 100% test coverage on all the features of the database we use. We can build queries using type safe query beans. IDE auto-complete when writing queries, compile time checking and it's FUN. Optimize queries to only fetch what we need (partial objects). Automatically avoid N+1 via a smart load context. -

Orator
The Orator ORM provides a simple yet beautiful ActiveRecord implement.
The Orator ORM provides a simple yet beautiful ActiveRecord implementation. The Orator ORM is based on conventions to avoid the hassle of defining every single aspect of your models. It is inspired by the database part of the Laravel framework, but largely modified to be more pythonic. All you need to get you started is the configuration describing your database connections and passing it to a DatabaseManager instance. If you have multiple databases configured you can specify which one is the default. For MySQL and PostgreSQL, the connectors are configured to return unicode strings. If you want to use the previous behavior just set the use_unicode configuration option to False. Once you have configured your database connection, you can run queries. To run a set of operations within a database transaction, you can use the transaction method which is a context manager. -

node-orm2
Object Relational Mapping
Supported: 4.0 + If using Nodejs >= 14 & Postgres, you must use pg driver >= 8.1. v7 doesn't work correctly (tests time out). Tests are run on Travis CI If you want you can run tests locally. Create Models, sync, drop, bulk create, get, find, remove, count, aggregated functions. Create Model associations, find, check, create and remove. Define custom validations (several builtin validations, check instance properties before saving - see enforce for details). Model instance caching and integrity (table rows fetched twice are the same object, changes to one change all). Plugins: MySQL FTS , Pagination , Transaction, Timestamps, Migrations. A Model is an abstraction over one or more database tables. Models support associations. The name of the model is assumed to match the table name. Models can be in separate modules. Simply ensure that the module holding the models uses module.exports to publish a function that accepts the database connection, then load your models however you like. -

SSQML
A schema to describe ANSI/ISO SQL in XML and associated tools
SSQML: Standard Structured Query Markup Language This is an XML dialect that allows any valid SQL statement, clause, expression, predicate, or query to be expressed fully in XML based on an XML compliant schema. The schema is based on Backus Normal Form (BNF) representations of ANSI-ISO/IEC SQL Standards; ISO/IEC 9075 :2003, ISO/IEC 9075 :2006, ISO/IEC 9075 :2008, ISO/IEC 9075-14 :2013 XML-Related Specifications (SQL/XML) Does not include support for Embedded SQL Ada, C, COBOL, Fortran, MUMPS, Pascal, or PL/I programs. These may be added in future. This schema was generated by automation taking the SQL BNFs as input. It was then run through schema validators and manually modified further to result in a valid schema. The schema was designed such that if an instance document has its tags removed and the order of the content preserved, a valid SQL statement or fragment will be left. A JAXB library with javadocs that represent ssqml.xsd are checked into SVN -

EF Core
Object-database mapper for .NET
EF Core is a modern object-database mapper for .NET. It supports LINQ queries, change tracking, updates, and schema migrations. Entity Framework Core is a modern object-database mapper for .NET. It supports LINQ queries, change tracking, updates, and schema migrations. EF Core works with many databases, including SQL Database (on-premises and Azure), SQLite, MySQL, PostgreSQL, and Azure Cosmos DB. To install EF Core, you install the package for the EF Core database provider(s) you want to target. This tutorial uses SQLite because it runs on all platforms that .NET Core supports. This application intentionally keeps things simple for clarity. Connection strings should not be stored in the code for production applications. You may also want to split each C# class into its own file. Query and manage relational data in a .NET Core app with an Object-Relational Mapper (O/RM). -
