GORM is a developer-focused object-relational mapping library for Go that provides a comprehensive data persistence framework. It serves as a database access layer, allowing developers to map application structures to database tables and perform CRUD operations using a fluent, type-safe query builder instead of writing raw SQL. The library distinguishes itself through its association-aware persistence, which automatically tracks and synchronizes complex entity relationships during database operations. It utilizes a driver-agnostic interface to maintain consistent behavior across various stora

MyBatis is a Java persistence framework that functions as a database query mapper and object-relational mapping tool. It decouples SQL statements from application code, allowing developers to manage database interactions by mapping Java objects to relational database records. The framework provides a centralized approach to SQL query management, enabling the use of either XML configuration files or annotations to define persistence logic. It automates the transformation of database result sets into structured objects, which eliminates the need for manual data conversion and reduces repetitive

Dapper is a high-performance micro-ORM and SQL object mapper for .NET. It functions as an ADO.NET extension library that adds data mapping capabilities directly to database connections, allowing SQL query results to be transformed into typed objects. The project prioritizes execution speed and low memory overhead by using intermediate language generation to map database columns to object properties. It further optimizes performance through the use of concurrent caching for mapping functions and literal value injection to improve database execution plans. The library covers a broad range of d
High-performance micro-ORM for mapping database results to objects.
EntityFramework is a .NET object-relational mapper that translates application objects into database tables and rows. It functions as a query engine that converts high-level expressions into optimized SQL commands for data retrieval. The project provides a mechanism for monitoring modifications to loaded objects to synchronize application state with the database. It also includes a system for synchronizing database structures with data models using versioned migration scripts. The framework supports multi-backend database integration through a plugin system, allowing a single application to
Standard data access framework with LINQ and POCO support.
greenDAO is an object-relational mapping library for Android that maps Java objects to SQLite databases. It provides infrastructure for high-performance data persistence by translating data objects into database records and vice versa. The library implements a type-safe query builder for retrieving records across multiple entities using joins and relationship chaining. It also includes a security layer that provides full-disk encryption for the SQLite database to prevent unauthorized access to stored information. The system utilizes compile-time code generation to create mapping classes, avo
Implements an object-relational mapping system to translate Java objects into SQLite database records.
jOOQ is a type-safe SQL query builder for Java that generates code from live database schemas, enabling compile-time validation of SQL syntax and data types. Its core identity is built around a fluent DSL that mirrors SQL structure, a code generator that maps tables, views, and routines to Java objects, and a multi-dialect engine that translates the same DSL into vendor-specific SQL for over 30 databases. The project also includes a SQL parser and transformer for refactoring or dialect conversion, reactive stream integration for non-blocking query execution, and a JDBC proxy diagnostics tool f
Type-safe SQL query construction and database integration.
Hibernate ORM este un mapper obiect-relațional pentru Java și o implementare completă a Jakarta Persistence API. Acționează ca un strat de abstractizare pentru baze de date SQL care traduce modelele de obiecte Java în scheme de baze de date relaționale pentru a gestiona persistența și ciclurile de viață ale datelor. Framework-ul se distinge printr-un sistem de izolare a datelor multi-tenant pentru separarea datelor clienților în cadrul unei singure instanțe de bază de date. De asemenea, dispune de un generator de scheme de baze de date care produce și actualizează automat structurile relaționale pe baza mapărilor de entități. Sistemul acoperă domenii vaste, inclusiv gestionarea tranzacțiilor, controlul concurenței prin blocare și urmărirea datelor temporale pentru audit. Oferă instrumente pentru optimizarea interogărilor prin strategii de tip entity-graph și suportă tipuri de date avansate, cum ar fi datele vectoriale și caracterele naționalizate. Proiectul include o suită cuprinzătoare de utilitare de testare pentru stratul de persistență, inclusiv filtrarea dialectelor de baze de date și testarea conformității cu specificațiile.
Core object-relational mapping functionality for Java.
pg is a PostgreSQL object-relational mapper (ORM) for Go that maps Go structs to database tables and provides a fluent query builder for constructing SQL statements programmatically. At its core, it automatically generates CREATE TABLE statements from Go struct definitions using struct tags and naming conventions, and builds queries through method chaining with placeholder-based parameter binding to prevent SQL injection. The library distinguishes itself through relation-aware join generation that automatically constructs JOIN clauses for has-one, has-many, many-to-many, and polymorphic assoc
PostgreSQL-focused ORM.
Querydsl este un framework pentru construcția de interogări type-safe. Utilizează un API fluent și generarea de cod bazată pe adnotări pentru a crea clase oglindă din modelele de domeniu, permițând validarea la compilare a interogărilor bazei de date și eliminând nevoia de concatenare manuală a șirurilor. Proiectul oferă o sintaxă de interogare unificată care se traduce în dialecte specifice pentru mai multe backend-uri, inclusiv SQL, MongoDB, Lucene și JDO. Suportă capabilități avansate de interogare, cum ar fi expresii tabelare comune, funcții de fereastră, operații geospațiale și subinterogări complexe imbricate. Dincolo de regăsirea datelor, framework-ul acoperă execuția DML type-safe pentru actualizări și ștergeri în masă, precum și maparea rezultatelor în Java Beans, constructori sau tuple. Include suport pentru interogarea colecțiilor în memorie și se integrează cu Spring Framework pentru gestionarea tranzacțiilor și a conexiunilor.
