  • Complex Data Mappings: Aligning disparate data fields and formats to ensure consistency. This may involve transforming data types, normalizing values, and standardizing formats.

2. Data Consolidation

Consolidation combines data from various sources, eliminating duplicates and resolving discrepancies:

  • Deduplication Algorithms: Utilizing techniques like fuzzy matching to identify duplicate records that are not identical but represent the same entity.
  • Creation of Golden Records: Establishing a consolidated master record that represents the most accurate and complete data about a specific entity, such as a customer or product.

3. Data Synchronization

Synchronization maintains the consistency of master data across all organizational systems:

  • Real-Time or Near-Real-Time Synchronization Protocols: Using technologies like Enterprise Service Buses (ESB) and API management platforms to propagate updates immediately.
  • Publish/Subscribe Mechanisms: Systems that automatically notify subscribing applications when changes occur in master data.

4. Data Governance

Establishing robust policies and procedures to ensure data quality, integrity, and security:

  • Defining Roles and Responsibilities: Appointing data stewards responsible for monitoring and maintaining quality standards.
