Aesthetic improvement of the model's appearance

Ensuring response times below three seconds

Proper arrangement of table rows in storage

Striving to keep response times within a few minutes

Discuss

Answer: (c).Proper arrangement of table rows in storage Explanation:A part of the "Ease of Administration" objective in the physical design of a data warehouse includes proper arrangement of table rows in storage to avoid frequent reorganization.

Q23.

What does "Design for Flexibility" imply in the context of physical design for a data warehouse?

Striving to keep response times within a few minutes

Keeping the design open to facilitate changes to the data model

Coping with the supergrowth period

Achieving scalability by managing storage space efficiently

Discuss

Answer: (b).Keeping the design open to facilitate changes to the data model Explanation:"Design for Flexibility" in the context of physical design for a data warehouse implies keeping the design open to facilitate changes to the data model.

Q24.

What is the primary goal of transforming a logical model into a physical model in a data warehouse?

Enhancing communication with users

Reflecting information content closer to the hardware

Improving data access patterns

Simplifying the data structure

Discuss

Answer: (b).Reflecting information content closer to the hardware Explanation:The primary goal of transforming a logical model into a physical model in a data warehouse is to reflect information content closer to the hardware.

Q25.

What are some major components of the physical model in a data warehouse?

Tables, attributes, primary keys, and relationships

File sizes, field lengths, data types, primary keys, and foreign keys

Logical model versions, physical model versions, and user communication

Naming conventions, object names, and delineators

Discuss

Answer: (b).File sizes, field lengths, data types, primary keys, and foreign keys Explanation:Major components of the physical model in a data warehouse include file sizes, field lengths, data types, primary keys, and foreign keys.

Q26.

Why are standards for naming objects in a data warehouse environment significant?

To simplify the data structure

To enhance communication among project members

To improve data access patterns

To reduce the need for delineators

Discuss

Answer: (b).To enhance communication among project members Explanation:Standards for naming objects in a data warehouse environment are significant to enhance communication among project members.

Q27.

How does the naming convention contribute to effective communication in a data warehouse project?

By simplifying the data structure

By adopting specific delineators

By conveying the meaning and description of the object

By eliminating the need for naming standards

Discuss

Answer: (c).By conveying the meaning and description of the object Explanation:The naming convention contributes to effective communication in a data warehouse project by conveying the meaning and description of the object.

Q28.

Why is it important to have consistent object names in both logical and physical models?

To improve data access patterns

To simplify the data structure

To enhance communication with IT professionals

To facilitate communication with users

Discuss

Answer: (d).To facilitate communication with users Explanation:It is important to have consistent object names in both logical and physical models to facilitate communication with users, as users refer to the physical model for data retrieval.

Q29.

What is the primary purpose of adopting effective standards for naming data structures in the staging area of a data warehouse?

To simplify the data structure

To avoid confusion and track files effectively

To improve data access patterns

To eliminate the need for naming standards

Discuss

Answer: (b).To avoid confusion and track files effectively Explanation:The primary purpose of adopting effective standards for naming data structures in the staging area is to avoid confusion and track files effectively.
