ITPEC FE Subject A October 2024 Question 18
ITPEC FE Subject A October 2024 — Question 18 of 60
Relational Database — a database design using linked tables with rows and columns.
A relational database organizes data into tables (relations), where each table has rows (records) and columns (attributes). Tables are linked through matching data (foreign keys).
Why not others:
- (a) Hierarchical database — tree structure with parent-child relationships
- (b) Network database — graph structure where a child can have multiple parents
- (c) Object-oriented database — stores data as objects (like in OOP)
Key rule: "Multiple tables + rows/columns + linked through matching data" = relational database.
