LiteDB is an embedded NoSQL database for .NET applications. It stores BSON documents in a single database file and does not require a separate database server.
The database is designed for applications that need local persistent storage while retaining the querying and indexing capabilities of a document database. It provides an API similar in concept to MongoDB, allowing developers to work with collections containing BSON documents.
LiteDB can map application classes directly to database records. Developers can use ordinary .NET objects rather than manually constructing document structures for every database operation.
The database supports transactional updates and includes recovery mechanisms for interrupted write operations. Its storage engine allows multiple readers to access data while coordinating modifications to preserve consistency.
LiteDB also offers query facilities that integrate with .NET development practices. Applications can use expressions to select records or execute SQL-like queries for more complex retrieval operations.
It is particularly suitable for desktop applications, small services and tools that need a self-contained document database.
This is free and open source software.
