ITPEC FE Subject A October 2025 Question 20
ITPEC FE Subject A October 2025 — Question 20 of 60
Distributed Database — data is split across multiple physical locations with distributed processing.
A distributed database stores different parts of data in different locations (nodes), and query processing is distributed across those nodes. To the user, it appears as a single logical database.
Why not others:
- (a) — describes shared access to a single server, not distributed architecture
- (b) — describes open data distribution to researchers, not a database architecture concept
- (c) — NoSQL is a data model choice, not the same as distributed; relational databases can also be distributed
Key rule: "Distributed" = data physically split across locations + processing spread across nodes.
