Agenda • Motivation –Why DVO ? • Introduction – DVO • DVO Architecture • Features supported in DVO • Key pointers on DVO • Reports Generation • Demo • Questions?
Motivation- Why DVO • Huge amount of data .What should I do ?? • Large volumes of data in heterogeneous environments • Manual Vs Automation • Regression Test • Test Results (Reporting) • Data Completeness and Accuracy
Introduction – DVO • Data validation Option is an Automated ETL Testing tool which comes along with power center and enables to test and validate data • Helps in verifying the completeness and accuracy of data after data migration • Reads table definitions from Power Center metadata repositories
Features supported in DVO • Table Pair • Single Table Constraints • SQL Views • Lookup Views • Join Views • Aggregate Views • Import and Export of Test • XML and Flat File Test • Aggregate Test and Expression • Report generation
What can’t be Tested vs What can be Tested What can’t be Tested ? • Mappings and Workflows can’t be tested • It doesn’t attempt to identify Bug in ETL process • Can’t Identify the source of inconsistencies What can be Tested ? • Only data validation can be done • DVO only reads table definition from PowerCenter Metadata repositories ,and checks the data at either end of the process • Can identify inconsistency in data
DVO POC Demo • Table Pair (2 Different database through SQL View) • Table Pair ( 2 Different database through Table Pair) • Single Table (Aggregates and Constraint Check through SQL View) • Single Table (Aggregates and Constraint Check through Table Pair) • Flat File (Through SQL View) • Fat File(Through Table Pair) • Table Pair ( 2 homogenous database through Join View)
Power center Steps: Launch Informatica Power centerdesigner and connect to INFAPCD1 Repository
Right Click on AJAY_PGI_DEST_POC folder and Add Single Table Test.Browse to locate Table and Provide connection detail for table. Specify one primary key
Add Test case to Single Table Test and add constraints for testing
