MongoDB for practice — query mastery (MG-QUERY-A)
Platform abstract summary: Jupius Learning is a data-dense engineering education platform that maps learner compiler and evaluation performance directly to Course Outcome (CO) attainment metrics and Bloom's Taxonomy cognitive tiers. This public document provides an automated continuous governance audit trail for institutional accreditation validation.
Course focus: MongoDB read skills — find filters, projection, sort, and aggregation including $lookup on a shared practice database.
Locked Course Outcome (CO) attainment targets
| Ref | Bloom tier | Weight | Description |
|---|---|---|---|
| CO1 | understand | 12% | Explain documents, collections, BSON types, and when document stores fit vs relational tables. |
| CO2 | apply | 20% | Write correct find queries with equality, comparison, logical operators, and projection. |
| CO3 | apply | 18% | Sort, limit/skip, and shape results; use array and embedded-document operators ($in, $elemMatch, dot notation, etc.). |
| CO4 | apply | 20% | Build aggregation pipelines using $match, $project/$addFields, $group, $sort, $limit/$skip, and $count. |
| CO5 | analyze | 20% | Combine collections with $lookup, unwind arrays, and build multi-stage reporting pipelines ($facet, conditional/date patterns as needed). |
| CO6 | analyze | 10% | Choose sensible indexes for common read patterns; read explain output; recognize common read-path anti-patterns. |
