## What it is
Chloe is a lightweight, high-performance Object/Relational Mapping (ORM) library for .NET written in C#. It provides a LINQ-like query interface supporting joins, group and aggregate queries, inserts, batch updates/deletes, and sharding across multiple databases.

## Use cases
- query databases with LINQ-style lambda expressions in .NET
- map C# entities to relational database tables
- perform join and group queries without writing raw SQL
- batch update and delete rows efficiently
- support multiple databases like SqlServer, MySQL, PostgreSQL, Oracle, SQLite
- work with Chinese databases like Dameng and KingbaseES

## When to choose
- you need a lightweight, fast ORM for .NET with LINQ-like syntax
- you need to support multiple database providers including Chinese databases
- you want fine control over generated SQL without a heavy framework

## When to avoid
- you need a full-featured ORM ecosystem with migrations and change tracking like EF Core
- your team prefers widely documented mainstream ORMs
- you rely on non-relational or NoSQL data stores

## Facets
- artifact type: library
- maturity: active
- function: orm, database, database-driver
- domain: databases, backend, developer-tools
- platform: dotnet, cross-platform
- tags: linq-queries, multi-database, lambda-expressions, c-sharp
