In a survey of potential customers we asked:

What are your top

DWH testing challenges?

They need to automate the testing effort

Their Top 6 Responses

They need to speed up the testing cycle

built by

They need to be able to schedule test runs

They need to be able to test across different platforms

They need to share test results with their group

They need to verify more data than they currently do (typically <10%)

automates the testing effort the kickoff, the tests, the comparison, emailing the results

speeds up testing up to 1,000 times faster than manual testing

schedules test runs run now, every Tuesday at 11pm or right after ETL process

tests across different platformsany JDBC-compliant database, DWH, D-Mart, flat file, XML

views & shares results through automated emailing of reports

the QuerySurge solution…

verifies more data verifies upwards of 100% of all data

QuerySurge Value-Add

QuerySurge provides value by either:

in testing data coverage from < 10% to upwards of 100%

in testing time by as much as 1,000 x 

combination of in test coverage while in testing time

19built by

Return on Investment (ROI)

redeployment of head count by 75% because of an increase in coverage

a savings over manual testing (minus queries, manual compares, other)

an increase in better data due to shorter / more thorough testing cycle, saving $millions by preventing key decisions made on bad data.
