EMBA vs LiteDB

EMBA has no write-up on Specifiction yet; its figures are above.

LiteDB is a free, open-source, serverless .NET NoSQL document database distributed as a single DLL. It stores data in one file and supports ACID transactions, with WAL mode for recovery from write failures. Queries can use SQL-like commands or LINQ, and query EXPLAIN plans are available. LiteDB maps POCO classes to BsonDocument and offers a fluent API for custom mapping. Its intended uses include mobile apps, desktop and local applications, application file formats, web applications, and per-user data stores. FileStorage can keep files and streams in the database, though each root BSON document has a documented 16 MB limit. LiteDB describes itself as thread-safe, with cross-collection transactions, no reader locks, and per-collection writer locks. Password-protected datafile encryption uses salted AES; the documentation specifies ECB mode and says changing or removing a password requires rebuilding the file. LiteDB is free for everyone, including commercial use, under the MIT License. It is installable through NuGet, and the project links to LiteDB.Studio as an administration tool.
