Detailed Answer in Step-by-Step Solution:
Objective: Differentiate data scientist vs. data engineer roles. Define Roles:
Data Engineer: Builds pipelines, prepares data. Data Scientist: Analyzes data, builds models.
Evaluate Options:
A: Engineer preps, scientist analyzes—Correct division. B: Reverses roles—Incorrect.
C: Overlaps roles—Scientist doesn’t typically build pipelines. D: Misaligns—Analyst isn’t the focus.
Reasoning: A reflects standard role separation. Conclusion: A is correct.
OCI documentation notes: “Data engineers focus on collecting and preparing data through pipelines,
while data scientists analyze it to derive insights and build models.” A aligns, B inverts, C
overcomplicates, and D shifts focus—only A is accurate.
