  1. 1. built by the automated Data Testing solution QuerySurge™
  2. 2. Where QuerySurge™ fits in your data strategy built by QuerySurge™
  3. 3. Business Intelligence (BI) software CxOs are using Business Intelligence & Analytics to make critical business decisions – with the assumption that the underlying data is fine. “The average organization loses $8.2 million annually through poor Data Quality.” - Gartner ETL Data Architecture The Executive Office and Critical Data potential problem areas
  4. 4. Current Business Case for Data Testing built by QuerySurge™ “46% of companies cite data quality as a barrier for adopting Business Intelligence products” - InformationWeek “On average, U.S. organizations believe 32% of their data is inaccurate” – Experian Data Quality research report “Poor data quality is a primary reason for 40% of all business initiatives failing to achieve their targeted benefits” - analyst firm Gartner “90% percent of U.S. companies have some sort of data quality solution in place today” – Experian Data Quality research report Data quality solutions are not enough!
  5. 5. o Profiling o Parsing and standardization o Generalized Cleansing o Matching o Monitoring o Enrichment o Subject-area-specific support o Metadata management o Configuration environment Data Quality tools vs. Data Testing tool built by QuerySurge™  Data Completeness  Data Transformation  Regression Testing Primary Characteristics of Data Quality tools courtesy of Gartner’s “Magic Quadrant for Data Quality Tools” Data Verification & Validation? Primary Characteristics of Data Testing tools Courtesy of the book "Testing the Data Warehouse Practicum" Data Verification & Validation?
  6. 6. Definitive Data Testing Book built by QuerySurge™
  7. 7. DataTesting Compare methods built by 1) Sampling (also known as “Stare & Compare” ) 2) Minus Queries
  8. 8. Method #1: Stare & Compare built by QuerySurge™ • Review Business Rules (i.e. Mapping Document: data flow mapping, data movement requirements) • Write Tests in SQL editor • Execute 2 Tests: 1 at Source & 1 at Target • Dump results to 2 Excel files • Compare results by eye (‘Stare & Compare’ or ‘sampling’) Issue with Stare & Compare: Impossible to visually compare billions of data sets. Result: usually less than 1% of data is compared Example: Current QuerySurge customer has: • a single test with 100 million rows & 200 columns • = 20 billion data sets • the client has > 7,000 total tests
  9. 9. built by QuerySurge™ MINUS QUERIES subtract one result set from another result set to show difference Comment: MINUS QUERIES need to be executed 2x (Source MINUS Target; Target MINUS Source) Result sets may not be accurate when dealing with duplicate rows of data No historical data from past testing – audit and regulatory issues Processing of minus queries puts pressure on the servers Double execution means 2x testing time and resource utilization Method #2: Minus Queries Minus Query #1: Table_1 MINUS Table_2 Minus Query #2: Table_2 MINUS Table_1 Result Set #1 Result Set #2 ISSUES with MINUS QUERIES Write 2 MINUS queries in SQL editor Execute MINUS queries 2x
  10. 10. DataTesting Compare Methods: 2 issues built by QuerySurge™ 1) There is a fundamental issue with both current methods: The assumption that all team members can write SQL/HQL code 2) Neither method fully satisfies any of the conditions below: Data Completeness Data Transformation Regression Testing
