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

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

Fast and simple bulk insert (retain client populated Ids or return db generated Ids), bulk update, bulk delete, bulk merge and bulk match for SQL Server.

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

Slonik is a type-safe PostgreSQL client for Node.js that uses tagged template literals to ensure parameters are bound and protected against injection attacks. It provides a framework for connecting applications to PostgreSQL with automatic type checking for queries and database schemas. The project distinguishes itself through a specialized SQL query linter that detects invalid columns and type mismatches by verifying code against a live database schema during the development process. It also includes a high-performance binary bulk data inserter for loading large datasets using native binary

Mongoose is an object data modeling library and framework for Node.js that maps application objects to MongoDB documents. It functions as a document mapper and schema validator, ensuring consistent data types and validation rules for records stored in MongoDB. The project provides a system for defining structured schemas to model application data, including the ability to create hierarchical data structures through nested schema composition. It implements a middleware-based hook system that allows for the interception and modification of data states during the lifecycle of database operations
