Fast and easy. No Programming needed. The latest QuerySurge release introduces the new Query Wizards. The Wizards allow both novice and experienced team members to validate their organization's data quickly with no SQL programming required. The Wizards provide an immediate ROI through their ease-of-use and ensure that minimal time and effort are required for developing tests and obtaining results. Even novice testers are productive as soon as they start using the Wizards! According to a recent survey of Data Architects and other data experts on LinkedIn, approximately 80% of columns in a data warehouse have no transformations, meaning the Wizards can test all of these columns quickly & easily, (The columns with transformations can be tested using the QuerySurge Design library using custom SQL coding.) There are 3 Types of automated Data Comparisons: - Column-Level Comparison - Table-Level Comparison - Row Count Comparison There are also automated features for filtering (‘Where’ clause) and sorting (‘Order By’ clause). The Wizards provide both novices and non-technical team members with a fast & easy way to be productive immediately and speed up testing for team members skilled in SQL. Trial our software either as a download or in the cloud at www.QuerySurge.com. The trial comes with a built-in tutorial and sample data.

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

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

3 Types of Data Comparison Wizards:
The also provide you with automated features for:
o filtering (‘Where’ clause) and
o sorting (‘Order By’ clause)
Column-Level Comparison:
This is great for Big Data stores and Data Warehouses where tables will have some columns
containing transformations and some columns with no transformations. Many tables and
columns can be compared simultaneously and quickly.
Table-Level Comparison:
This comparator is great for Data Migrations and Database Upgrades with no
transformations at all. Many tables can be compared simultaneously and quickly.
Row Count Comparison:
Great for all - Big Data stores, Data Warehouses, Data Migrations and Database Upgrades.
Many tables and rows can be compared simultaneously and quickly.

18. Uses:
Tests the columns that have no
transformations, which means it tests
approximately 80% of your data store without
you writing any SQL code
Tests:
Big data, data warehouses
Value added:
novice or non-technical: no coding needed,
productive immediately
experienced user: saves time
