Design and Implementation of an Operational Backend System Using ETL, Metadata, and Business Object Model

The paper outlines the three‑generation evolution of a video‑platform operational backend—from Apollo to Eight—meeting cross‑business integration, low‑cost development, and user experience goals by employing a metadata‑driven ETL layer, a unified business‑object model, and a componentized UI within a micro‑kernel, plugin‑based architecture, delivering decoupling, rapid configuration, data safety, and dynamically generated pages, while future work expands UI components, source support, deep‑operation features, and PaaS/open‑source release.
