ITPEC FE Morning April 2023 — Question 25 of 80
Relational Database Model — stores data as two-dimensional tables (rows and columns).
A relational database organizes data into tables (also called relations), where:
- Each row (tuple) is a record
- Each column (attribute) is a field
Why not others:
- (a) "parent-child with pointers" → hierarchical database model
- (c) "structure and meaning using tags" → XML / markup-based data
- (d) "data and procedures encapsulated" → object-oriented database model
Key rule: "Two-dimensional table" = relational database. This is the defining characteristic.
