Answer & Solution
Answer: Option A
Solution:
The answer is
A: True.
Here's why:
Think of building a house:
1. First, you decide
what rooms you need (entities) - like kitchen, bedroom, bathroom.
2. Then, you decide
what each room will have (attributes) - like kitchen has a sink, stove, refrigerator. Bedroom has a bed, wardrobe.
3. Finally, you decide
how the rooms connect (relationships) - like the kitchen is next to the dining room, the bedroom is upstairs.
Similarly, in database design:
*
Entities are like the main objects you want to store information about (e.g., Customer, Product, Order).
*
Attributes are the properties of those objects (e.g., Customer has Name, Address, Phone Number).
*
Relationships show how these objects relate to each other (e.g., a Customer places an Order).
So,
identifying entities, then attributes, then relationships is a fundamental and correct approach in database design using ER models.
