SurrealDB Multi-Model

SurrealDB is a multi-model database that combines relational (SQL-like), document (JSON), graph (relationships), and vector (embeddings) data models in a single system. Instead of using PostgreSQL for relational data, MongoDB for documents, and Neo4j for graphs, SurrealDB is one database for all three. It's built in Rust, designed for modern applications, and supports edge deployment and browser-based WASM. The query language (SurrealQL) unifies SQL-like syntax with document and graph operations.
