Data Modeling With Er Model - Study Mode

Explanation

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.
