How does What are Databases? - Definition & Meaning work technically?
Relational databases (PostgreSQL, MySQL) follow the ACID model with tables, relationships and SQL queries. NoSQL includes document stores (MongoDB), key-value (Redis), wide-column (Cassandra) and graph databases (Neo4j). Cloud databases (Supabase, PlanetScale) offer managed hosting. Choice depends on schema flexibility, scale and query patterns.
How does MG Software apply What are Databases? - Definition & Meaning in practice?
MG Software primarily uses PostgreSQL and Supabase for relational data. We choose Redis for caching and sessions. For large amounts of unstructured data or real-time sync we consider NoSQL. We always document database choice and design.
What are some examples of What are Databases? - Definition & Meaning?
