When comparing MongoDB and SQL databases, it's essential to understand their fundamental differences, use cases, and advantages.
Definition and Data Storage
MongoDB is an open-source NoSQL database developed by MongoDB, Inc. It stores data in JSON-like documents that can vary in structure, making it highly flexible and scalable. Each record in MongoDB is stored as a document within a collection.
SQL databases (e.g., MySQL, PostgreSQL) are relational databases that use Structured Query Language (SQL) for defining and manipulating data. Data is stored in rows within tables, and the schema is fixed. Each table consists of rows and columns, with predefined relationships between tables using foreign keys.
Schema and Flexibility
MongoDB offers a dynamic schema, allowing for the insertion of new fields without affecting existing documents. This flexibility makes it suitable for applications where the data structure may evolve over time.
