Question
Which logical role in the NIST reference architecture is responsible for providing raw data for processing?
A. Data Consumer
B. Big Data Application Provider
C. Data Provider
D. System Orchestrator
Answer
C. Data Provider
Explanation
In the NIST Big Data Reference Architecture (NBDRA), the Data Provider is the logical role responsible for supplying raw data to the system for processing. This role introduces new data or information feeds, which are essential for downstream activities such as data analysis, storage, and integration. The Data Provider serves as the entry point for data into the Big Data ecosystem.
The NBDRA outlines five primary roles, each with distinct responsibilities:
- System Orchestrator: Oversees and manages the overall operation of the Big Data system, including defining requirements and ensuring that all components work together seamlessly.
- Data Provider: Supplies raw data to the system, which can originate from various sources such as sensors, databases, or external systems.
- Big Data Application Provider: Processes and analyzes the data to generate insights or value-added services.
- Big Data Framework Provider: Provides the infrastructure and tools required for data processing, storage, and management.
- Data Consumer: Utilizes the processed data outputs, such as reports or visualizations, for decision-making or further application.
Why is “Data Provider” Correct?
The Data Provider’s primary function is to introduce raw data into the system, making it available for subsequent stages of processing and analysis. Without this role, there would be no input for the Big Data pipeline to operate on. This aligns with its designation in NIST’s framework as a critical component for initiating data workflows.
Incorrect Options
A. Data Consumer: This role uses processed data rather than supplying raw data.
B. Big Data Application Provider: Focuses on analyzing and processing data, not providing it.
D. System Orchestrator: Manages system operations but does not directly supply raw data.
Understanding these roles is crucial for professionals aiming to implement or analyze Big Data systems effectively, especially when preparing for certifications like APMG International’s Certified Enterprise Big Data Professional (EBDP).
