Standardizing definitions through a centralized data governance framework ensures consistency. Collaborative workshops and working groups can help reconcile different perspectives and establish common definitions.

  3. Multiple Levels of Granularity Needed Different use cases require data at varying levels of granularity. Balancing the need for detailed, granular data with the requirements for aggregated, high-level data can be challenging. Implementing flexible data architecture that supports multiple views and aggregations can address this issue.

  4. Lack of Historical Data to Resolve Issues Historical data is crucial for trend analysis and resolving data quality issues. However, many organizations lack comprehensive historical records due to poor data retention policies. Establishing robust data archiving practices and leveraging technologies like data lakes can help preserve valuable historical data.

  5. Differences in Standards and Lack of Common Vocabularies Variations in standards and vocabularies across departments hinder data integration and interoperability. Adopting industry-standard data models and terminologies can mitigate these issues. Additionally, developing an enterprise-wide glossary and encouraging its use can promote consistency.


  1. Integrating MDM Tools and Processes into an Enterprise Architecture Seamlessly integrating MDM tools and processes into the existing enterprise architecture is a complex task. Legacy systems, disparate data sources, and evolving business requirements add to the complexity. A phased approach to integration, starting with high-priority areas and gradually extending to other parts of the organization, can be effective.

  2. Extending the MDM Framework with Additional Capabilities As business needs evolve, the MDM framework must be extended with new capabilities, such as advanced analytics, machine learning, and real-time data processing. Ensuring that the MDM infrastructure is scalable and flexible enough to accommodate these enhancements is critical. Investing in modular and adaptable technologies can facilitate such extensions.

  3. Inability of Technology to Automate All Curation Scenarios While technology can automate many aspects of data curation, certain scenarios still require human intervention. Complex data relationships, contextual understanding, and nuanced decision-making are areas where technology falls short. Building a collaborative environment where technology augments human expertise rather than replacing it is essential for effective data curation.

Effective data mastering is a multi-faceted endeavor that requires addressing challenges related to people, processes, information, and technology. By fostering alignment in data governance objectives, establishing robust processes, ensuring data quality and consistency, and leveraging adaptable technologies, organizations can overcome these challenges and achieve a cohesive and reliable master data management strategy.

Informatica MDM - SaaS - IDMC - Address Verifier Reference Data for Postal Verification

 Address reference data serves as an authoritative source for postal addresses within a country. In many instances, this data includes comprehensive details for every postal address in a country. When using a Verifier transformation in mapping processes, input address data is compared against these reference files to ensure accuracy.

How the Verification Process Works

The verification process involves the following steps:

  1. Comparison: Each element of the input address is individually and collectively compared against the reference data to confirm it matches a single, deliverable address.
  2. Results: The mapping results provide verified or corrected addresses along with any additional requested information.

Key Guidelines for Address Reference Data

Here are essential rules and guidelines to manage and use address reference data effectively:

  • File Download: The Secure Agent automatically downloads the current versions of the required files. If a current version already exists on the host machine, it won't be downloaded again.
  • File Verification: During downloads, hash files are also downloaded. These hash files are used to verify the reference data's current status during mapping operations.
  • File Integrity: Reference data files and hash files are read-only. They should not be moved or deleted.
  • Storage Location: The default storage location for these files is [Informatica_root_directory]/avdata. This location can be reviewed or updated in the Administrator service. If changed, the data is downloaded to the new location during the next mapping run.
  • Disk Space: Ensure ample disk space for these files. The required space varies based on the countries and number of files. A complete set of global reference data files needs approximately 18 GB of disk space.
  • Download Time: Large volumes of reference data might extend download times.
  • Licensing: Reference data files require a valid license. The verifier accesses license information from license files specified as a data property on the Secure Agent.
  • Geographical Restrictions:

    Address reference data enabling certified verification for United States addresses is licensed exclusively for use within the United States.

By adhering to these guidelines, the verification process ensures that address data is accurate, up-to-date, and complies with licensing requirements, thus facilitating efficient and reliable postal address management.
