A reporting system publishes reports on a website where users log in and retrieve them on demand. What report delivery mode is this? Select the single best answer.

Introduction / Context:
Report delivery models determine how information reaches consumers. Two common patterns are “push” and “pull.” Understanding them helps design reporting workflows that fit user needs and system load.

Given Data / Assumptions:

• Reports are hosted on a site.
• Users initiate access by browsing or clicking links.
• No automatic emailing or broadcasting is described.

Concept / Approach:

In a pull model, users request reports when needed (self-service portals, dashboards). In a push model, the system delivers reports proactively (scheduled emails, subscriptions, alerts). RFM and OLAP are analytics concepts, not delivery modes.

Step-by-Step Solution:

Verification / Alternative check:

Examples: logging into a portal or dashboard is pull; receiving a scheduled email report is push.

Why Other Options Are Wrong:

Push: system-initiated delivery. RFM: segmentation technique. OLAP: analytical approach, not a delivery mode.

Common Pitfalls:

Confusing “publish” with “push.” Publishing makes content available; it does not imply proactive distribution.

Final Answer:

Pull
