NOSQL — definition?

Non-relational databases handling large-scale, distributed data.

Scaling — horizontal method?

Adding more servers/nodes to distribute workload.

Schema-less Data — advantage?

Allows flexible, dynamic data models.

CAP Theorem — properties?

Impossible to guarantee all three: consistency, availability, partition tolerance.

Horizontal Scalability — role?

Increases capacity by adding servers.

CAP Theorem — property?

Impossible to guarantee all three: Consistency, Availability, Partition Tolerance.

Eventual Consistency — meaning?

Data updates propagate asynchronously, eventual uniformity.

NOSQL DBMS types — examples?

Key-value, document, column, graph.

Graph Databases — purpose?

Model complex interrelationships and connections.
