Question

Quizplus · Accepted Answer

A data mart is a subset of a data warehouse that contains selected data focused on a specific business unit or department. It is designed for easy access to specific information and is usually smaller and more focused than the broader data warehouse. Data marts can help eliminate data duplication and provide standardized data formats, but their primary function is to provide quick and easy access to relevant data for specific business needs. They may include master data, but they also include transactional data and other types of data as needed to support the business unit or department they serve. Option A is more closely associated with data integration, Option C is not accurate, Option D describes a report rather than a data mart, and Option E is a benefit of data marts but not their primary purpose.
