SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Quality teams need a compact, actionable reference to quickly gauge tabular data quality and guide remediation decisions.

Core Features & Use Cases

  • Concise quality-dimension guide covering completeness, uniqueness, validity, consistency, accuracy, and conformity.
  • Remediation decision tree to determine appropriate fixes across datasets and pipelines.
  • Use cases include profiling CSV/Parquet data, validating datasets for analytics, and guiding governance workflows.

Quick Start

To start, review the quality dimensions and use the remediation tree to identify the first corrective action.

FAQPage Schema
How do I assess data quality dimensions like completeness and uniqueness in tabular datasets?

Data quality assessment evaluates tabular datasets against six dimensions: completeness, uniqueness, validity, consistency, accuracy, and conformity. It applies a statistics-based framework to profile data and identify specific quality issues in analytics pipelines and warehouses.

What is the best way to remediate data quality issues found during data profiling?

Data quality remediation uses a structured decision tree to determine appropriate fixes for identified issues. This guides corrective actions across datasets and pipelines, moving directly from profiling discovery to a recommended remediation step.

Can I validate CSV and Parquet data for analytics pipelines without external dependencies?

Yes, CSV and Parquet datasets can be validated directly within analytics pipelines and data governance workflows. The process requires no external dependencies, applying a statistics-based evaluation framework to check conformity and validity.

How does a data quality remediation decision tree work for data warehouse governance?

A remediation decision tree maps identified quality failures to specific corrective actions for data warehouse governance. It evaluates the statistics-based profile of the dataset to recommend whether to fix, flag, or drop non-conforming records.

When should I use a statistics-based data quality framework instead of manual checks?

A statistics-based data quality framework should be used when profiling large tabular datasets for analytics pipelines where manual checks fail. It efficiently scales completeness, uniqueness, and consistency evaluations across entire data warehouses.
