MongoDB and relational database: a comprehensive comparison
Apr 08, 2025 pm 06:30 PM
MongoDB and relational database: In-depth comparison This article will explore in-depth the differences between NoSQL database MongoDB and traditional relational databases (such as MySQL and SQLServer). Relational databases use table structures of rows and columns to organize data, while MongoDB uses flexible document-oriented models to better suit the needs of modern applications. Mainly differentiates data structures: Relational databases use predefined schema tables to store data, and relationships between tables are established through primary keys and foreign keys; MongoDB uses JSON-like BSON documents to store them in a collection, and each document structure can be independently changed to achieve pattern-free design. Architectural design: Relational databases need to pre-defined fixed schema; MongoDB supports
