TIBCO Data Virtualization 4

Question 1

In TIBCO Data Virtualization, what does 'data masking' accomplish for sensitive columns?

Accepted Answer

Replaces real sensitive values with obfuscated values for unauthorized users

Answer

Data masking in TDV substitutes real values (e.g., SSNs, credit card numbers) with masked equivalents for users who lack access to the raw data.

Question 2

What is the TDV 'Business Directory' used for?

Accepted Answer

Providing a searchable catalog of published data assets for business users

Answer

The Business Directory is a self-service catalog that lets business users discover and understand available published data resources.

Question 3

When TDV performs a federated join between an Oracle source and a Salesforce source, where does the join computation occur by default if neither source can handle the full query?

Accepted Answer

In TDV's in-memory execution engine on the server

Answer

When push-down is not fully possible, TDV retrieves partial result sets from each source and performs the join in its own in-memory engine.

Question 4

Which TDV configuration setting limits the maximum number of rows returned by a virtual view to prevent runaway queries?

Accepted Answer

Row Limit Governor

Answer

The Row Limit Governor in TDV caps the number of rows a query may return, protecting source systems and server memory from unbounded result sets.

Question 5

In TDV's SOAP web service publishing, what document defines the operations and data types exposed by a TDV service?

Accepted Answer

WSDL (Web Services Description Language)

Answer

TDV generates a WSDL document that describes the SOAP service interface, including input/output message schemas and operation names.
