What is the benefit of using an InfoSource in a data flow? (1)

Question

Options

• AProvide an interface for extracting data a query
• BPersist htermediate results
• CAvoid using a DataSource
• DConnect multiple sequential transformations

Explanation

An InfoSource functions as an intermediary layer in a data flow that enables chaining multiple transformations in sequence - data flows through one transformation, lands at the InfoSource, then continues into the next. This is its primary architectural benefit: it acts as a logical connector between transformation steps, allowing complex, multi-stage processing pipelines to be structured cleanly.

Why the distractors are wrong:

• A is wrong because extracting data via a query is the role of a DataSource, not an InfoSource.
• B is wrong because persisting intermediate results is the job of a Persistent Staging Area (PSA) or staging table, not an InfoSource.
• C is wrong because InfoSources work alongside DataSources - they don't replace them; data still originates from a DataSource.

Memory tip: Think of an InfoSource as a pipeline junction - just as a road junction links multiple road segments, an InfoSource links multiple transformation segments in a data flow sequence. If you remember "InfoSource = connection point between steps," option D will always stand out.
