  • Standardizing universal codes across all states, counties and jurisdictions
  • Mining multiple databases to unlock hidden facts (e.g. ARM details)
  • Refining valuations with overlaid demographics, statistics, etc.

Don't become a casualty of "garbage in, garbage out" mentality. Count on our data integrity when making key business decisions.

Quantitative and qualitative analysis. The world of market research relies on these two vital information categories to gain effective insights.

This led us to pioneering “linkable data”―connecting unrelated pieces of information to produce a new generation of algorithmic analytics and predictive modeling.

About CoreLogic Data - Quality

In the world of data collection, order is everything. At CoreLogic, we begin by applying strict standardization to all incoming data. Because we gather data from a wide array of sources in numerous formats with all kinds of anomalies, we adhere to a rigorous governance program to create a structural foundation. Some features of our data assurance process include:

  • All data checked at aggregate level for inconsistent behaviors and greater-than-expected changes from prior reporting
  • All data run through automated edit checks to catch anomalies
  • Irregular data verified against outside sources—or removed

Business decisions depend on timely information. That's why every one of our databases is dynamically updated 24/7/365, continuously receiving and applying new information as it becomes available.

Data must make sense, fit your needs and meet specific regulatory standards. To meet those requirements, we normalize our databases by eliminating redundant information and ensuring that dependencies are logical and query efficient. Given the heavily regulated nature of much our data, our cleansing process includes making sure that information complies with appropriate regulatory and client standards.

Normalization & Compliance

We implement the following in our normalization and compliance process:

  • All data standardized to work with intended systems and applications
  • All data reviewed for compliance with legal, industry and client standards
  • Securitized loan tools confirmed to ensure no loans are included that shouldn't be
  • Securitized pools verified to confirm existing loan deals have legitimate terminations (payoff, liquidation, repurchase, etc.)

We protect our data with physical and digital security measures. Our data centers are built on base-isolator shock absorbers so that they can withstand temblors many times the magnitude of the 1906 San Francisco earthquake. In addition, advanced digital security protects against unauthorized access, use, disclosure, disruption or modification. Ongoing security procedures include security audits, regular system testing, rigorous staff training and continuously updated business-continuity planning.


Some features of our data security include:

  • Ongoing assessments to monitor risk and compliance
  • Access rights and data-use monitoring to find and fix vulnerabilities
  • Close monitoring of sensitive files to identify noncompliance arising from rule changes
  • Rigorous adherence to legal, industry and client standards
