Redundancy
The degree to which logically identical data are stored more than once.
- •Reduced data storage costs and streamlined data management.
- •Improved data consistency as updates only need to be made in one place (if mastered).
- •Simplified data landscapes and reduced complexity.
- •Lower risk of inconsistencies arising from multiple, out-of-sync copies of data.
- •Increased storage costs and inefficient use of resources.
- •Higher risk of data inconsistencies if redundant copies are not synchronized perfectly.
- •Increased complexity in data management, updates, and reconciliation.
- •Wasted effort in maintaining and validating multiple instances of the same data.
Number
Logistics: Customer address is stored once in a central Customer Master Data system, and all other systems reference this single source of truth.
HR: Employee data is mastered in the HRIS, and other systems requiring employee information access it via integration or replication from this authoritative source.
Product Management: Product Information Management (PIM) system acts as the central repository for all product data, which is then syndicated to other channels.
Logistics: Customer address information is stored redundantly in the sales system, billing system, and shipping system, leading to inconsistencies when an address changes and isn't updated in all places.
HR: Employee emergency contact details are captured in the HRIS, a separate departmental spreadsheet, and a local manager's contact list.
Product Management: The same product specifications (e.g., dimensions, weight) are manually entered and stored in the ERP, the e-commerce platform, and the marketing collateral database.
