You need to integrate customer data stored in separate marketing, sales, and support databases. These sources use varying formats and field names for similar attributes like customer name and contact information. What strategy will you use to create a unified dataset that eliminates inconsistencies and ensures accuracy across all sources?
Reformat individual fields without reconciling their differences
Develop a central framework with consistent attributes and map all source data to align with this structure
Secure sensitive data by anonymizing selected fields
Remove records that lack required fields or contain errors
Merging and harmonizing data from multiple sources into a standardized framework ensures consistency and dependability. Strategies that involve masking sensitive information or discarding incomplete rows address specific issues but do not establish a consistent data structure.
