⚡ NoSQL Databases
NoSQL databases are database systems that use flexible data models instead of traditional relational tables, often storing data in 
JSON or BSON formats.
They typically use document, key-value, wide-column, and graph storage models, and support horizontal scaling, distributed storage, schema flexibility, high write throughput, graph relationships, replication, and fault-tolerant architectures.
