Data Warehousing in Pharma: How to Find Bad Data while Meeting Regulatory Req...

In the U.S., pharmaceutical firms must meet electronic record-keeping regulations set by the Food and Drug Administration (FDA). The regulation is Title 21 CFR Part 11, commonly known as Part 11. Part 11 requires regulated firms to implement controls for software and systems involved in processing many forms of data as part of business operations and product development. Enterprise data warehouses are used by the pharmaceutical and medical device industries for storing data covered by Part 11. QuerySurge, the only test tool designed specifically for automating the testing of data warehouses and the ETL process, is the market leader in testing data warehouses used by Part 11-governed companies.

Data Warehouse Testing in the Pharmaceutical Industry

In the U.S., pharmaceutical firms and medical device manufacturers must meet electronic record-keeping regulations set by the Food and Drug Administration (FDA). The regulation is Title 21 CFR Part 11, commonly known as Part 11. Part 11 requires regulated firms to implement controls for software and systems involved in processing many forms of data as part of business operations and product development. Enterprise data warehouses are used by the pharmaceutical and medical device industries for storing data covered by Part 11 (for example, Safety Data and Clinical Study project data). QuerySurge, the only test tool designed specifically for automating the testing of data warehouses and the ETL process, has been effective in testing data warehouses used by Part 11-governed companies. The purpose of QuerySurge is to assure that your warehouse is not populated with bad data. In industry surveys, bad data has been found in every database and data warehouse studied and is estimated to cost firms on average $8.2 million annually, according to analyst firm Gartner. Most firms test far less than 10% of their data, leaving at risk the rest of the data they are using for critical audits and compliance reporting. QuerySurge can test up to 100% of your data and help assure your organization that this critical information is accurate. QuerySurge not only helps in eliminating bad data, but is also designed to support Part 11 compliance. Learn more at www.QuerySurge.com

DataTesting Strategy #1: Stare & Compare
built by
QuerySurge™
• Review Mapping Document (business rules, 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)
Difficulty with Stare & Compare:
Impossible to visually compare millions/billions of data sets visually.
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
Data Tester’s Current Process
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
Potential for false positives (bad data could exist on both sides of an ETL leg)
DataTesting Strategy #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

Whitepaper: Volume Testing Thick Clients and Databases

Even in the current age of cloud computing there are still endless benefits of developing thick client software: non-dependency on browser version, offline support, low hosting fees, and utilizing existing end user hardware, to name a few. It's more than likely that your organization is utilizing at least a few thick client applications. Now consider this: as your user base grows, does your think client's back-end server need to grow as well? How quickly? How do you ensure that you provide the correct amount of additional capacity without overstepping and unnecessarily eating into your profits? The answer is volume testing. Read how RTTS does this with IBM Rational Performance Tester.

Let’s face it: marketing is in a big data bubble. Everyone is talking about data: big data, data analytics, and big data analytics. At the root of all this data mania in marketing is the very real revolution that’s shaping more data-driven organizations. Big data is finally opening the door to the executive suite for a more hybrid creative-analytical method. The key question data raises is how do we use it to not only know more about our customers, but to directly grow our business in significant ways? Iron Mountain has the answer: broadly embrace testing and controlled experimentation as the new “operating system” of marketing. The answer to big data’s potential is big testing.

Test Automation for Data Warehouses

This document discusses challenges and opportunities in automating testing for data warehouses and BI systems. It notes that while BI projects have adopted agile methodologies, testing has not. Large and diverse data volumes make testing nearly infinite test cases difficult. It proposes a testing lifecycle and V-model for BI systems. Automating complex functional tests, SQL validation, reconciliation, and test data generation can help address challenges by shortening regression cycles and enabling continuous testing. Various automation tools are discussed, including how they can validate ETL processes and reporting integrity. Automation can help complete testing and ensure data quality, compliance, and performance.

This document presents a business case for adopting Real Application Testing (RAT) to test upgrades and patches for a large insurance company's data warehousing system. It estimates that using RAT could reduce testing labor hours by 41% and yield a payback period of less than 12 months due to savings in upgrade costs, monthly patching costs, and production support costs. Adopting RAT could potentially provide even greater savings if it was used to test all 53 applications in the system or reduce issues across all patch upgrades.

  • 2. built by QuerySurge™ About FACTS Founded: 1996 Locations: New York (HQ), Atlanta, Philadelphia, Phoenix Strategic Partners: IBM, Microsoft, HP, Oracle, Teradata, HortonWorks, Cloudera, Amazon Software: QuerySurge RTTS is the leading provider of software & data quality for critical business systems
  • 3. “70% of enterprises have either deployed or are planning to deploy big data projects and programs this year” – analyst firm IDG “46% of companies cite data quality as a barrier for adopting Business Intelligence products.” - InformationWeek “Poor data quality is a primary reason for 40% of all business initiatives failing to achieve their targeted benefits.” - analyst firm Gartner Data Quality Issues built by QuerySurge™
  • 4. 2 Prevalent DataTesting Strategies built by QuerySurge™ 1) Stare & Compare 2) Minus Queries
  • 5. DataTesting Strategy #1: Stare & Compare built by QuerySurge™ • Review Mapping Document (business rules, 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) Difficulty with Stare & Compare: Impossible to visually compare millions/billions of data sets visually. 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 Data Tester’s Current Process
  • 6. 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 Potential for false positives (bad data could exist on both sides of an ETL leg) DataTesting Strategy #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

Editor's Notes

  1. I typically read the quotes
  2. Talk through the process
  3. 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.
  4. 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.
  5. 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.
  6. 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.
  7. 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.
