Rule Library

Start data quality monitoring with a proven rule foundation.

The Perfect Data Rule Library provides a curated starting point for data quality monitoring across industries, regulatory regimes, and reporting domains—so teams don’t have to start from a blank page.

Industry-aware Regulation-informed Repeatable patterns Faster onboarding
Why the library exists

Most data quality programs stall because teams must invent rules, definitions, and expectations from scratch. The Rule Library accelerates adoption by capturing common patterns seen across real-world programs.

Key idea
Use the library as a starting point—not a ceiling. Rules are designed to be adapted to your data, definitions, and risk tolerance.

What the Rule Library contains

The library is organized around common data quality failure modes rather than one-off checks. This makes it easier to apply rules across different systems and architectures.

  • Completeness patterns for required and critical fields
  • Validity and format checks aligned to business expectations
  • Referential and relational integrity concepts
  • Timeliness and freshness expectations
  • Cross-field and cross-table consistency patterns

Industry and regulatory focus

The Rule Library reflects monitoring needs seen across regulated and data-intensive industries.

  • Financial services (banking, lending, asset management)
  • Regulatory reporting and risk data programs
  • Operations and analytics data pipelines
  • Enterprise reporting and executive dashboards
  • Internal governance initiatives tied to audits and controls

How teams use the Rule Library

The library is designed to support different stages of program maturity.

Getting started

Teams select a subset of relevant rules to quickly establish baseline monitoring on critical reports and datasets.

Adapting to context

Rules are customized to reflect local definitions, thresholds, data models, and operational tolerance for defects.

Expanding coverage

As programs mature, teams extend the library with organization-specific rules while maintaining consistent patterns and naming.

Designed for governance
The Rule Library supports governance discussions by standardizing how quality expectations are expressed, reviewed, and evolved across teams.
