•
2 j'aime•51,337 vues
The document discusses QuerySurge, an automated data testing solution that helps verify data quality and find errors. It notes that traditional data quality tools focus on profiling, cleansing and monitoring data, while QuerySurge also enables data testing through easy-to-use query wizards and comparison of source and target data without SQL coding. QuerySurge allows collaborative testing across teams and platforms, integrates with development tools, and can significantly reduce testing time and improve data quality.

QuerySurge - the automated Data Testing solution
- 1. built by the automated Data Testing solution QuerySurge™
- 2. Where QuerySurge™ fits in your data strategy built by QuerySurge™
- 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. 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!

- 6. Definitive Data Testing Book built by QuerySurge™
- 7. DataTesting Compare methods built by 1) Sampling (also known as “Stare & Compare” ) 2) Minus Queries
- 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. 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

Notes de l'éditeur
- QuerySurge provides insight into the health of your data throughout your organization through BI dashboards and reporting at your fingertips. It is a collaborative tool that allows for distributed use of the tool throughout your organization and provides for a sharable, holistic view of your data’s health and your organization’s level of maturity of your data management.
- QuerySurge finds bad data by natively connecting to: any data source, whether it is any type of database, flat file or xml and can connect to any data target, whether it is a db, file, xml, data warehouse or hadoop implementation. QuerySurge pulls data from the source and the target and compares them very quickly (typically in a few minutes) and then produces reports that show every data difference, even if there are millions of rows and hundreds of columns in the test. These reports can be automatically emailed to your team. You can pick from a multitude of reports or export the results so that you can build your own reports.
- Your distributed team from around the world can use any of these web browsers: Internet Explorer, Chrome, Firefox and Safari. Installs on operating systems: Windows & Linux. QS connects to any JDBC-compliant data source. Even if it is not listed here.
- QuerySurge can utilized by active practitioners such as testers & developers to create and launch tests, or by managers, analysts and operations to view data test results and the overall health of the data. QuerySurge facilitates this by providing 2 types of licenses: (1) full user & (2) participant user. (1) Full User – This type of user has unlimited access to create QueryPairs, Suites, and Scenarios. This user can also schedule and run tests, see results, run and export reports, and export data. Perfect for anyone creating and/or running data tests while performing analysis of results. (2) Participant User – This user cannot create or run tests, but has access to all other information - including viewing all query pairs, results, and reports, receiving email notifications, and exporting test results and reports. Perfect for managers, analysts, architects, DBAs, developers, and operations users who need to know the health of their data.
- QuerySurge helps your team coordinate your data quality initiatives while speeding up your development and testing cycles and finding your bad data. Why risk having your team identify trends and develop strategic initiatives when the underlying data is incorrect? QuerySurge reduces this risk.
