QuerySurge - the automated Data Testing solution
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.

- 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

Editor's Notes
- #12 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.
- #14 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.
- #15 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.
- #16 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.
- #25 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.
