UnQLite 是一个嵌入式的软件库，实现了自容器、无服务端、跨平台、零配置和支持事务的 NoSQL 数据库引擎。UnQLite 是一个文档存储数据库，类似于 MongoDB, Redis, CouchDB 等。同时也是一个标准的 K/V 存储，类似 BerkeleyDB, LevelDB 等。采用C语言编写开发并在BSD协议下授权使用。
UnQLite is a in-process software library which implements a self-contained, serverless, zero-configuration, transactional NoSQL database engine. UnQLite is a document store database similar to MongoDB, Redis, CouchDB etc. as well a standard Key/Value store similar to BerkeleyDB, LevelDB, etc.
UnQLite is an embedded NoSQL (Key/Value store and Document-store) database engine. Unlike most other NoSQL databases, UnQLite does not have a separate server process. UnQLite reads and writes directly to ordinary disk files. A complete database with multiple collections, is contained in a single disk file. The database file format is cross-platform, you can freely copy a database between 32-bit and 64-bit systems or between big-endian and little-endian architectures.
