⚡ SQL Databases

SQL databases are relational database management systems that store data in structured tables with defined relationships and use the Structured Query Language (SQL) to query and modify data.

They typically support ACID-compliant transactions, replication, stored procedures, concurrency control, full-text search, JSON and geospatial data handling, indexing, backup tools, and access control mechanisms for protecting data.
