Which of the following actions is required when setting up drill-through to a relational database as a source system?

When establishing drill-through connectivity from Oracle Cloud EPM Data Integration to a relational database source, establishing connectivity parameters is mandatory. Configuring the database connection string (including JDBC URL, driver details, username, and password) enables the Data Integration engine or EPM Integration Agent to authenticate, connect, and execute SQL queries directly against the relational database tables or views. Without a properly configured connection string, the system cannot establish communication with the target external database or retrieve the required drill-through query results.

A. Manual data validation is an operational control step, not a technical setup requirement for database drill-through.

C. Financial report automation relates to reporting execution, independent of database drill-through setup.

D. Drill-through is an interactive, on-demand query triggered by users, not a scheduled batch job.
