📖 1. Purpose of Data Access

🔑 Key Concepts & Definitions

• Purpose (see introduction): The business objective for which data is accessed and used. It specifies why the data is being used, such as CRM campaign management, marketing targeting, analytics, or reporting. AUTHOR (date): "Purpose represents the business objective for which the data will be used."

• Business Objective for Data Usage: The specific goal or reason behind accessing data, aligned with organizational needs and compliance requirements. It guides the permissible scope of data use and helps prevent misuse. AUTHOR (date): "The purpose is the intended use of data that aligns with business objectives."

• Difference between who accesses data and why data is accessed: The distinction emphasizes that access control (who can access) is separate from the reason for access (why they need it). Knowing who accesses data does not imply understanding why they need it, which is critical for proper data governance. AUTHOR (date): "Today, data access only considers who can access what, but not why the data is accessed."

📝 Essential Points
