Oracle Database Cloud Service Implementation Essentials — Question 1

If a customer is planning on building a data warehouse, how would you describe data warehousing to the customer?

Answer options

• A. The data in the data warehouse describes events and statuses of business processes, products and services, goals and organizational units, and generally mirrors every aspect of the structure and behavior of the organization.
• B. Data warehouses can only be based on multidimensional data modeling.
• C. Application based data warehouses can be bought off the shelf and used without any tweaking.
• D. Data warehouse projects are usually implemented within two weeks.

Correct answer:

Explanation

The correct answer is A because it accurately captures the comprehensive nature of data warehousing, reflecting the organization's structure and operations. Option B is incorrect as data warehouses can utilize various modeling techniques, not just multidimensional. Option C is misleading since off-the-shelf solutions typically require customization to fit specific business needs, while option D is unrealistic given the complexity of data warehouse implementations.
