SQL databases use a relational model and are vertically scalable, while NoSQL databases are non-relational, horizontally scalable, and support semi-structured or unstructured data. NoSQL databases provide eventual consistency and are easier for programmers to use compared to SQL databases, which support atomic transactions but can be more difficult for programmers. Common types of NoSQL databases include document, graph, key-value pair, and column-oriented databases.

• RDBMS
• SCALE UP/Vertically
Scalable
• Structured or Schema
• Atomic Transaction
• Difficult for programmer
• Eg. CAR Disassembled in
and reassembled when
required.
NOSQL
• NonRelational
• Scale OUT/Horizontally
Scalable
• Semi or unstructured data
• EVENTUAL CONSISTENCY
• Easy for Programmers
• Eg. Park a car in parking
