Introduction to Informatica Data Validation Option Training
Informatica Data Validation Option is the process of verifying the accuracy and completeness of data after a data migration, replication, integration or other similar movement or transformation exercise. Valid and accurate target data indicates that the data extraction, transformation and loading (ETL) processes are working as expected and are safe to use. DVO integrates with the Informatica PowerCenter Repository and Integration Services and enables developers and business analysts to create rules to test the data.

The DVO platform interoperates with the broadest possible range of disparate standards, systems and applications. This unbiased and universal view makes informatica unique in today’s market as a leader in the data integration platform. Informatica Power Center is a premium data integration solution available today. The reason it provides the best solution for the large enterprises is that its database is neutral and hence can communicate with any database and it is the most powerful data transformations tool and converts one application’s data to another format.
Informatica DVO and Power Center
DVO is tightly integrated with Informatica Power Center. Informatica Power Center and Informatica DVO are two different tools. Informatica Power Center is an ETL tool where as DVO is a data validation and testing tool. DVO and power center have a separate license. Without power center you cannot configure or use DVO.
Informatica DVO Architecture
DVO consists of a desktop client and its own combined metadata repository and warehouse. The metadata repository and the warehouse is a single database in which DVO metadata and the results of test cases are stored in predefined warehouse tables.
Informatica DVO Database
You have to create a separate database specific to DVO. The database will have all the DVO metadata tables, test definitions and test results are stored in the database. The database will also have predefined warehouse views on which all reporting occurs.
When you configure DVO, you need to define source power center repository and target power center repository.
Source Power center repository:
DVO uses the source power center repository to import the metadata that is source objects, target objects, folder list and connection objects from the power center.
For instance, let’s say you need to compare data between a flat file and relational table. In order to create the test cases in DVO on these objects, you need to first import the flat file and relational table in the source power center repository. Then, refresh the folder in DVO for you to see the objects in DVO. Any source, target or connection object cannot be imported in DVO directly. The objects can only be imported from the source power center repository.
Target Power center repository:
When you create test cases and execute in DVO, DVO automatically generates informatica mapping, session, workflow to compare and validate source and target data. The generated informatica objects are stored in the target power center repository. You can configure the same power center repository as source and target repository in DVO.
DVO connects to power center source repository and imports the required objects i.e., source, target, folder list and connection objects. You create test cases in DVO client and the metadata like the source, target, connection and the DVO test case details are stored in the DVO repository. The test case execution is handled by target power center repository. DVO will generate the mapping, session and workflow based on the DVO test case configuration defined in the DVO client. Power center will access the data being tested using the connection information which is specified in the DVO test case configuration and applies the DVO test case configuration to the data.
Test results like pass or fail, test details, error rows and data values are loaded by target power center repository into the DVO warehouse. Users can view test results in the DVO client and users can generate different reports which are generated from warehouse.
