Relational databases (SQL) store data in tables with rows and columns, linked by relationships and foreign keys. They are the default choice for structured, transactional data in backend applications.
Lire l'article →Module 7: NoSQL Databases for Backend
NoSQL databases use storage models other than traditional relational tables. Common types: document (e.g. MongoDB), key-value (e.g. Redis), wide-column (e.g. Cassandra), graph (e.g. Neo4j). This module focuses on documen
