In Talend, when multiple components need to share the same database connection, thetDBConnectioncomponent is used.
tDBConnection (Correct Answer - Option D):
This component establishes a database connection that can bereused by multiple database components(such as tDBInput, tDBOutput, and tDBRow) within the same Job.
Reduces redundant connection creation,improving performance and efficiency.
To use it, other database components must set"Use an existing connection"in their configuration.
Why not other options?
tDBOutput (Option A):Used for writing data to a database but does not manage shared connections.
tDBRun (Option B):Used to execute a subJob but does not handle database connections.
tDBCommit (Option C):Used for committing transactions, but it requires a shared connection (which tDBConnection provides).
