LiteDB is a serverless NoSQL document store and embedded database engine for .NET applications. It persists unstructured documents and binary data into a single standalone disk file, allowing the database to run within the application process rather than as a separate server.
The system supports strongly typed queries through Language Integrated Query and allows the execution of standard SQL commands for data retrieval and transformation. It provides native mapping of plain classes into document formats and secures stored information via symmetric-key file encryption.
The engine includes capabilities for managing atomic transactions and indexing specific document fields to accelerate search performance. It also supports the storage and streaming of large binary files that exceed standard size limits.
