SurrealDB is an end-to-end cloud native database for web, mobile, serverless, jamstack, backend, and traditional applications. SurrealDB reduces the development time of modern applications by simplifying your database and API stack, removing the need for most server-side components, allowing you to build secure, performant apps quicker and cheaper. SurrealDB acts as both a database and a modern, realtime, collaborative API backend layer. SurrealDB can run as a single server or in a highly-available, highly-scalable distributed mode - with support for SQL querying from client devices, GraphQL, ACID transactions, WebSocket connections, structured and unstructured data, graph querying, full-text indexing, geospatial querying, and row-by-row permissions-based access

PostgreSQL also known as Postgres, is a free and open-source relational database management system (RDBMS) emphasizing extensibility and SQL compliance. PostgreSQL features transactions with atomicity, consistency, isolation, durability (ACID) properties, automatically updatable views, materialized views, triggers, foreign keys, and stored procedures. PostgreSQL은 확장성과 SQL 준수를 강조하는 무료 오픈 소스 관계형 데이터베이스 관리 시스템(RDBMS)입니다. PostgreSQL은 원자성, 일관성, 격리성, 내구성(ASID) 속성, 자동으로 업데이트 가능한 보기, 구체화된 보기, 트리거, 외부 키 및 저장 프로시저를 갖춘 트랜잭션을 특징으로 합니다.
