Data Management and Analytics Flashcards

What is data governance, and what is its primary objective in an organization?

Answer: A framework of policies, roles, and processes that ensure data is accurate, available, and used appropriately

Data governance establishes accountability through policies, standards, and stewardship roles to ensure data assets are managed consistently, accurately, and in compliance with regulations.

What is Master Data Management (MDM) designed to solve?

Answer: Creating and maintaining a single authoritative source of key business entities like customers, products, and locations

MDM creates a 'single version of the truth' for critical business entities, eliminating inconsistencies that arise when the same data is stored differently across multiple systems.

What does data lineage track within a data management framework?

Answer: The history of data's origin, movement, transformations, and usage over time

Data lineage provides a traceable record of where data originated, how it was transformed, and where it moved, which is critical for debugging, auditing, and regulatory compliance.

Under the General Data Protection Regulation (GDPR), what right allows EU citizens to request that their personal data be permanently deleted?

Answer: Right to erasure (Right to be forgotten)

The GDPR's Right to Erasure (Article 17) allows individuals to request that organizations delete their personal data under certain conditions, such as when it is no longer necessary for its original purpose.

What is a data catalog, and how does it support data management?

Answer: An inventory of data assets with metadata that helps users discover, understand, and trust available data

A data catalog indexes organizational data assets along with their metadata (definitions, ownership, lineage, quality scores), enabling analysts to find and understand available data efficiently.

Which data management principle states that data should be collected and stored only to the extent necessary for its specified purpose?

Answer: Data minimization

Data minimization, a core principle in GDPR and modern privacy frameworks, requires organizations to limit personal data collection to what is strictly necessary for the defined purpose.

In big data architecture, what does the 'velocity' dimension of the three Vs refer to?

Answer: The speed at which new data is generated and must be processed

Velocity describes the rate at which data is generated and flows into the system, requiring technologies that can ingest and process streams in near real-time (e.g., Apache Kafka, Flink).
