FaunaDB is a strongly consistent OLTP database that utilizes a unique hybrid document-relational data model. Originally developed as a database-as-a-service, it is now an open-source project that provides a flexible yet structured approach to data management.

The main features of this tool include:

• Hybrid Data Modeling: FaunaDB combines the flexibility of document models with the structured nature of relational databases, allowing for complex data patterns within a single system.

• Strong Consistency: It is designed for Online Transaction Processing (OLTP), ensuring that data remains accurate and consistent across transactions.

• Custom Query Language (FQL): The database is accessed via the Fauna Query Language (FQL), a dedicated NoSQL language designed specifically for its hybrid model.

• Broad Language Support: The project provides official drivers for multiple programming environments, including JavaScript, Go, Python, JVM, and .NET.

• Integrated Toolset: The open-source offering includes the original service code along with a Command Line Interface (CLI) and various language drivers to streamline development.

• Comprehensive Documentation: Users can access detailed guides and technical information through a dedicated documentation portal at docs.faunadb.org.
