LiteDB

No database server needed; runs embedded within the application with zero configuration, ideal for local storage and small web apps as highlighted in the philosophy.

All data is stored in one portable file, similar to SQLite, making deployment, backup, and sharing straightforward, as emphasized in the key features.

Ensures data integrity with full transaction support and write-ahead logging for recovery after write failures, providing robustness for small-scale applications.

Supports both LINQ for C# developers and a SQL-like syntax with indexing, allowing flexible querying as demonstrated in the code examples and new v5 features.
