EFCore.BulkExtensions is a library for executing high-performance batch insert, update, and delete operations within the Entity Framework Core ecosystem. It functions as a database batch processing toolkit and a wrapper for native SQL Bulk Copy to enable faster data ingestion and synchronization across multiple database providers. The library provides specialized capabilities for relational data synchronization, allowing users to align database tables with local entity lists through bulk upserts and conditional synchronization. It also supports relational data graph insertions, which enable t

HikariCP is a high-concurrency JDBC connection pooling library for Java applications. It provides a reusable set of database connections to reduce the overhead of creating new connections for every request, enabling low-latency database access for applications handling large volumes of simultaneous requests. The project utilizes lock-free connection pooling and non-blocking data structures to ensure high performance. It includes specialized optimizations such as bytecode-optimized statement caching on the driver side to reduce SQL parsing overhead and proxy-based connection wrapping to track

Official PetaPoco, A tiny ORM-ish thing for your POCO's

Strongly typed exceptions for Entity Framework Core. Supports SQLServer, PostgreSQL, SQLite, Oracle and MySql.

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

Gorp is a lightweight object-relational mapper for Go that binds structs to relational database tables. It functions as a relational data mapper and SQL dialect abstraction layer, automating the translation between application data and relational rows. The project provides a translation layer that generates vendor-specific SQL for PostgreSQL, MySQL, SQLite, Oracle, and SQL Server. It distinguishes itself by implementing optimistic locking via version columns to prevent concurrent update conflicts and providing a database schema generator to create tables and indexes from object definitions.

A better ORM for Go, based on non-empty interfaces and code generation.

A Tasty Treat For All Your Database Needs

Provides a simple API to fluently map POCO properties to database columns when using Dapper.

CRUD operations with Dapper made simple.

Hibernate ORM is a Java object-relational mapper and a full implementation of the Jakarta Persistence API. It serves as a SQL database abstraction layer that translates Java object models into relational database schemas to manage data persistence and lifecycles. The framework distinguishes itself with a multi-tenant data isolation framework for separating customer data within a single database instance. It also features a database schema generator that automatically produces and updates relational structures based on entity mappings. The system covers broad capability areas including transa

A flexible and powerful SQL string builder library plus a zero-config ORM.

The Jdbi library provides convenient, idiomatic access to relational databases in Java and other JVM technologies such as Kotlin, Clojure or Scala.

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
