After registering new data sources, you must complete your Bill Presentment Architecture by creating database views. How many database views can you create for each data source?

Question

Options

• Aone
• Bnine
• Cthree
• Dunlimited

• A
  95% (21)
• B
  5% (1)

Explanation

In Bill Presentment Architecture (BPA), each data source maps to exactly one database view - a strict one-to-one relationship enforced by the architecture's design. This constraint ensures a clean, predictable data layer where each source has a single, well-defined view governing how its data is exposed for bill formatting and retrieval.

Why the distractors are wrong:

• B (nine) and C (three) are arbitrary numbers with no basis in the BPA specification - they exist to test whether you've memorized the actual constraint.
• D (unlimited) is the most tempting wrong answer, since databases generally allow many views per table, but BPA imposes its own application-level restriction on top of raw database capability.

Memory tip: Think "one source, one view" - the word source has the same number of syllables as one view, reinforcing the 1:1 pairing. If you remember that BPA is built around simplicity and determinism in its data mapping layer, "one view per source" follows naturally.
