Patented ELV Architecture.
ETL Validator makes use of our patented ELV Architecture to automate ETL
Testing. It supports extraction of test data from multiple sources such as
relational databases, XML, Flat Files, BI and Hadoop. The test data is loaded into a workschema (Oracle or Postgresql database) so that validations can be run on it.
ELV (Extract, Load, Validate) Architecture consists of the following three steps:
Extract test data (and metadata) from heterogeneous data sources.
Load the test data into a workschema (oracle or postgresql database).
Validate test data by comparing it within the workschema.
