This lesson develops Business Model and Mapping Layer Design within Oracle BI 12c: Build Repositories Ed 1.
The work is anchored to a BI architecture team creating a reusable semantic model for finance, sales, and time-series reporting, so each decision is connected to a measurable operational result and an accountable owner.
The instructor models logical tables, logical columns, logical table sources, and content levels, then connects it to dimension hierarchies, levels, keys, drill paths, and aggregation grain. The demonstration captures the exact configuration, transaction, command, query, log, or screen evidence needed to prove intended behavior and the applicable control boundary.
Learners execute a guided lab focused on dimension hierarchies, levels, keys, drill paths, and aggregation grain and source mappings, transformations, fragmentation, and aggregate navigation. The exercise introduces a realistic exception related to consistency checking, ambiguous mappings, double counting, and model correction and requires a reversible correction supported by before-and-after evidence.
Acceptance requires accurate handling of source mappings, transformations, fragmentation, and aggregate navigation, traceable proof for logical tables, logical columns, logical table sources, and content levels, and a repeatable recovery path for consistency checking, ambiguous mappings, double counting, and model correction. Results must be understandable to both implementers and operational support teams.
Learners compare symptoms, logs, state, dependencies, and recent changes when consistency checking, ambiguous mappings, double counting, and model correction occurs. The final diagnosis must separate the immediate fix from the preventive control.
The completed output is a tested business model and mapping layer design implementation or analysis, with validation evidence, troubleshooting notes, rollback guidance, and a concise operational handover.
