Measuring Data Quality for Ongoing Improvement: A Data Quality Assessment Framework: The Morgan Kaufmann Series on Business Intelligence

Autor Laura Sebastian-Coleman
en Limba Engleză Paperback – 20 feb 2013

Publicul țintă principal al acestui volum este format din ingineri și manageri de date, analiști de conformitate și profesioniști în Business Intelligence, care primesc un instrumentar metodologic pentru transformarea datelor în active de încredere. Descoperim aici o abordare pragmatică a guvernanței, centrată pe cadrul DQAF (Data Quality Assessment Framework), menit să pună în acord limbajul tehnic al departamentelor IT cu prioritățile strategice de business. Notăm cu interes faptul că Laura Sebastian-Coleman nu tratează calitatea datelor ca pe un proiect cu termen de finalizare, ci ca pe un proces de îmbunătățire continuă, integrat în fluxul operațional.

Subliniem structura riguroasă a celor șase secțiuni, care ghidează cititorul de la definiții conceptuale și modele de metadate, până la scenarii complexe de evaluare și strategii de implementare. În comparație cu Data Quality de Carlo Batini, care oferă o perspectivă teoretică și sistematică asupra reglementărilor internaționale, lucrarea de față este mult mai orientată spre practică, oferind peste trei duzini de tipuri de măsurători specifice pentru dimensiuni precum integritatea și validitatea. De asemenea, dacă The Practitioner's Guide to Data Quality Improvement de David Loshin se concentrează pe socializarea și planificarea programelor de date, Measuring Data Quality for Ongoing Improvement merge în profunzime cu algoritmi de calcul și comparații pentru detectarea anomaliilor.

Această lucrare consolidează expertiza autoarei, fiind o continuare firească a temelor explorate în Navigating the Labyrinth și Meeting the Challenges of Data Quality Management. În timp ce lucrările anterioare puneau accent pe comunicarea cu liderii organizațiilor, volumul de față oferă detaliile tehnice și logice necesare pentru execuția propriu-zisă a strategiei de date.

Descriere scurtă

The Data Quality Assessment Framework shows you how to measure and monitor data quality, ensuring quality over time. You’ll start with general concepts of measurement and work your way through a detailed framework of more than three dozen measurement types related to five objective dimensions of quality: completeness, timeliness, consistency, validity, and integrity. Ongoing measurement, rather than one time activities will help your organization reach a new level of data quality. This plain-language approach to measuring data can be understood by both business and IT and provides practical guidance on how to apply the DQAF within any organization enabling you to prioritize measurements and effectively report on results. Strategies for using data measurement to govern and improve the quality of data and guidelines for applying the framework within a data asset are included. You’ll come away able to prioritize which measurement types to implement, knowing where to place them in a data flow and how frequently to measure. Common conceptual models for defining and storing of data quality results for purposes of trend analysis are also included as well as generic business requirements for ongoing measuring and monitoring including calculations and comparisons that make the measurements meaningful and help understand trends and detect anomalies.


  • Demonstrates how to leverage a technology independent data quality measurement framework for your specific business priorities and data quality challenges
  • Enables discussions between business and IT with a non-technical vocabulary for data quality measurement
  • Describes how to measure data quality on an ongoing basis with generic measurement types that can be applied to any situation
